StocExpo Review

StocExpo, Europe’s largest international tank storage and future fuels event returned to Rotterdam in March. The event which attracts hundreds of thought leaders from across the world to discuss the future of the bulk storage industry provided the perfect opportunity to unveil Contrec’s new one arm preset load controller to the tank storage and distribution market. 

Accredited with full Exd and IECEx certification for hazardous areas LoadPro® provides a safe and accurate solution for fuel and chemical loading in smaller chemical distribution hubs and fuel depots.

As the world’s energy requirements change to more sustainable sources, the technology and control solutions must adapt to meet these demands. The ability to safely and accurately measure these varied products in the petrochemical industries, is becoming more critical. Alternative fuels are driving the industry forward, Contrec’s Sales Director Craig Naylor talks about how Contrec’s systems can adapt easily to these changing requirements.

“As the fuels and chemical industries adapt to sustainable production methods, cleaner more efficient processes and increased flexibility for storage and transportation, the role of loading and unloading products safely, accurately and with instant visibility has never been more important. Contrec have been manufacturing electronic preset controllers since the 1980’s when automation of legacy mechanical systems began gathering pace.  In those 40 years we’ve learned and adapted our solutions to meet the constant shifting in technology and customer demands.  The modern day preset controller doesn’t just need to count the flow, it needs to operate reliably in sites that rarely close or maybe unmanned, to be able to integrate with every aspect of the loading/unloading process including authorising competent users and monitoring safety systems, to then produce transport documents and transmit that data to remote supervisory software for report generation or invoicing.

LoadPro® covers all these requirements in a simple to operate, compact system.  Our in-built RFID reader will authorise operators ensuring theft/misuse is minimised by only allowing approved users to load/unload products.  For extra security, a second authorisation can be used or assigned to vehicles to help maintain audit trails.

New installation or upgrading an old mechanical system? No Problem.  LoadPro® is as happy working with existing Positive Displacement or Turbine flowmeters as it is with new technologies such as Coriolis and Ultrasonic flowmeters. 

What about control?  The traditional method in petroleum applications of Digital Valve Control (DCV) is catered for, however we also handle simple On/Off valves and for some chemical applications 4-20mA modulating valves are catered for.

Can I compensate for temperature/pressure/density?  The answer is yes, we have the API/ASTM tables for oil products built in, and for those with specialist fluids then a custom table can be entered into the device to correct against.

What safety features are included? Earth, Overfill and Vapour Return alarms are covered by our permissive inputs which can be configured to pause or abort the load if triggered.  Emergency Stop circuits will instantly terminate the load.  All alarms are reported as ‘exceptions’ on the loading dockets so that these incidents are highlighted to supervisors.

What else does can LoadPro do? Gantry isolation/pump control output.  Deadman operation which ensures the operator remains near the loading point during operation. LoadPro® keeps a log of all transactions (up to 1500) so in the event of communications going down, no loads are lost, the loading can continue and historical transactions can be printed/downloaded to the supervisory system once comms are re-established.

The push towards alternative renewable fuels such as HVO (Hydrotreated Vegetable Oil), SAF (Sustainable Aviation Fuel), along with Bio-Diesel and Gasohol/Ethanol throws up the requirements to blend, add to this marking fuels to help prevent fraud or adding performance and efficiency improving chemicals requires additives, Contrec have a range of solutions to handle these tasks simply and accurately.      

For Volumetric or Mass Frequency Flowmeters, the LoadPro™ Load Controller has a range of application packs tailored to the various requirements found in single arm loading systems. It is a simple to use numeric controller with the capabilities for Dual Stage Relay, Digital Valve Control or Analogue Valve/VSD drive for the reliable and accurate delivery of preset quantities of liquid products. The frequency flow input, from volumetric or mass flowmeters, can accept aquadrature signal for ISO 6551 level B pulse security along with pressure, temperature and/or density inputs can be used to provide volume correction to recognised national standards.

Easily integrated with Datamod™ Contrec’s simple to use reporting software or most commercial TAS systems.

Contrec staff raise over £3000 for the Alzheimers Society

Last Saturday Contrec’s Marketing Manager Lucy Wood took on the arduous 25 mile Yorkshire three peaks challenge to raise money for the Alzheimer’s Society, the UK’s leading dementia charity.  Despite the high winds and rain and hail on the day (and one injured party!) Lucy, Jo and Kim, climbed Ingleborough, Whernside and Pen Y Ghent in just less than 10 hours!  Raising just over £3000 for this amazing cause. Well done girls!

Coronavirus Update 07-09-20

Contrec have implemented many changes during these uncertain times to protect our colleagues, suppliers and visitors to our offices. Throughout the Covid-19 epidemic, we have maintained a manufacturing presence and distribution for the many essential manufacturers out there who were increasing production or shifting their operations in order to produce increased quantities of sanitizer, hand wash and other products essential in helping the fight against Coronavirus. Contrec instruments play a crucial role in chemical, pharmaceutical production in accurately monitoring and blending liquids.
Thank you to all our customers and suppliers through these difficult times, and we look forward to being of mutual service throughout 2020 and beyond.

DataMod & Contrec, both IoT ready, welcome to the new 1.3.000 software release.

Contrec’s DataMod software package continues to evolve, and like most of Contrec’s development over the years new features have initially been developed for specific customer projects before being added to a general release. The benefit of this is that you know the features have real and genuine purpose and you can have confidence that not only are they expertly engineered, but that they have already been properly field tested before being released to the wider market.

In this DataMod release 1.3.000, we offer a host of new features, such as:

• Continued Improved User Interface as we take on feedback and DataMod gets wider uses
• Email Alerts for Auto and Live data collection applications
• Delivery Numbers can now used to specify the range of data collection for Load & Batch applications
• Stored Configuration Records for easy load and re-use to allow data collections from multiple 515 field instruments to be made much faster   and simpler, including with clear feedback when changes are made
• Easy Creation and Management of Configuration Records that hold all the settings to suit each individual field instrument or type of report      required.
• Stored Locations Remembered for CSV files and report templates making file handling faster.
• Further IoT Support and Readiness with refined TCP/IP interface being easier to configure and store separate IP addresses, falling in line       with the release of the new 515 Ethernet option card.

Read below our DataMod Case Study which highlights the benefits of the new software release and shows DataMod and Contrec are both IoT ready.

In this case the real field application involves two 515-LC01 Loading stations on a site where there is no access to any communication networks, their head office is over 3000 km away and needs to get weekly reports of all delivery transactions. Each loading station does approximately 80 deliveries a week to up to 50 different customers. On a Monday each week DataMod which is installed at the head office is used to collect the previous week’s delivery records. DataMod has access to both 515 field instruments as a result of Contrec moving comfortably into the new world of IoT.

These communications are via a combination of a secure and encrypted Virtual Private Network (VPN) on a Contrec managed internet cloud server, through to the cellular network to a 4G field gateway module with its own dedicated IP address. The particular gateway used has an RS485 port to which both 515 instruments are connected with their own Modbus RTU address. A VPN client and certificate (issued by Contrec) is installed on the computer where DataMod software is also installed. DataMod with its built in Modbus TCP/IP protocol has a stored configuration record for each field instrument with all the communication and address settings and custom text etc, specific to each instrument.
(In this project Contrec Systems supplied the IoT solution as a package, including the VPN server and client software and certificates, plus the configured 4G gateway with data subscription and IP addresses.)

When the DataMod operator is ready, they simply start the VPN connection, open DataMod and click to load the stored configuration for the required instrument. Once they establish connection this will show the most recent delivery number and then specify the delivery range required for the week’s report, before clicking again to start collecting.
When collection is complete the operator generates a PDF report with their own custom template and saves the data as a CSV file to integrate into their own inventory and reporting system.

From over 3000 kms away, the customer has a very economical and simple way to get the instrument delivery data and is able to see exactly what loads and volumes occurred and which client they were allocated to.

New Ethernet Port for the 515 Series

Ethernet Port

Contrec are delighted to announce that the 515 series Flow Instruments can now be ordered with an optional Ethernet port.

Ideal where there is an existing LAN (Local Area Network) or WAN (Wide Area Network) in place, it now simplifies the communication network and avoids the need for an external 3rd party Serial to Ethernet converter. The 515 can now connect into the network with its dedicated IP address making access to flow and batch data quick and simple without the large installed costs associated with running individual cabling from production areas back to the control room. Having an Ethernet port offers a stable, consistent signal compared to Wi-Fi installations, and is also a more secure and controlled environment for transmission of important data.
The Contrec 515 Ethernet port provides an ideal access route to our own DataMod software tool, making visibility of measurement and control information, data analysis and management decision making even quicker. 

For more information on our Ethernet options – Email sales@contrec.co.uk or call us on +44 1422 829944.

505 Series Instruments now integrated in to popular 515 range

From immediate effect the 505 Series range of instruments will now be integrated in to the popular 515 series. 

A number of components used in the manufacture of the Contrec 505 Series instrumentation have become obsolete and so we have taken the decision to migrate the 505 applications to the more advanced 515 platform with immediate effect.

The main benefits are:

• Same instrument housing, display and operator interface
• Selectable analogue or pulse input during configuration (hence versions  02 and 04 deleted)
• Universal mains power supply (100 – 240 VAC)
• Optional density input (live or manual value) so Volume and Mass can be displayed (FC applications only)
• Increased logging capability
• Compatible with Contrec DataMod Software Tool

We are pleased to advise that there will be no price increases to the FC and BC base model instruments.

Please don’t hesitate to contact your local Contrec Service Centre if you require any further information.

Contrec release new DataMod 1.2.000 software now with Inbuilt Modbus TCP/IP protocol plus many more features and benefits!

                        

Contrec’s new DataMod release 1.2.000 introduces a host of new features designed to make it even easier for engineers and managers using Contrec 515 instruments, to collect data, generate reports and automatically produce delivery dockets.

Since its release in 2017, Contrec’s DataMod software has been helping engineers and managers quickly and easily view and record what’s happening in their plant. No need for expensive customised SCADA packages, Contrec’s DataMod software tool has proved itself to be a one-size-fits-all solution allowing you to extract critical live or logged operating data from your Contrec 515 instruments installed in the field and to generate reports and spreadsheets quickly and easily.

Giving you much more

The latest DataMod 1.2.000 release sees additions such as Inbuilt Modbus TCP/IP protocol giving engineers the ability to connect via TCP/IP protocol without using third party software, making the process of configuration, connection and communication with remote instruments via Ethernet so much simpler.

Another great new feature relates to 515 Batch and Load applications, as DataMod can now continually monitor the 515 controller and allow managers of standalone systems to automatically generate and print a default or customised report (Delivery Docket or Bill of Lading) at the end of a delivery. This becomes a highly economical and efficient way to generate accurate and professional reports, with the convenient option of printing automatically on the computer’s existing office printer.

For a full list of the additional features and benefits that DataMod 1.2.000 has to offer please see below:

  • Collect Live Data – Applicable to General applications, DataMod now allows time-based data to be collected directly from a 515 Flow Computer/Controller on significantly smaller time periods than the 515’s internal hourly logging and can be set to collect up to 500 logs for a single report.
  • Auto Collect Data – Applicable to Load and Batch applications, DataMod now allows delivery data to be automatically collected directly from a 515 Load or Batch Controller. DataMod monitors the 515 controller to collect the data automatically as soon as a delivery is complete. The Rollover number (max 500) sets the number of deliveries to be included in the one report.
  • Auto Save Reports – Applicable to any setup using the Rollover number. Whenever a rollover occurs a report is saved in PDF and CSV format. This allows DataMod to operate unmanned or remotely, generating reports and saving them in the designated folder for later access.
  • Auto Print Reports – Applicable to any setup using Auto Save Reports this now allows DataMod to automatically print a Report to the host computers default office printer. In Load applications this provides a neat way for a driver/operator to collect the Delivery Docket directly from the control office or gate house printer without any interaction with the office computer or the DataMod program.
  • BOL Style Report Templates – Applicable to LP or LC Load applications, using the Load Template feature, a ‘free of charge’ default Bill of Lading style template can be selected to provide a very professional report with the minimum fuss. Your Contrec Service Centre can be contacted to have this template further tailored for a specific customer’s needs with company name, logo and product details etc.
  • View Last Auto Report – Applicable to any setup using the rollover number, this allows an operator to get quick access to the last delivery (BOL in loading applications) to view or get an additional printout.
  • Streamlining Setup and Smarter User Interface
    – Refined “Data Collection Options” & “Modbus Setup” screens to make initial configuration easier.
    – On initial comms ‘Connection’ with the instrument, DataMod prompts the operator to start collection (alerting the user to either start       collecting data or pause to adjust customizable tags)
    – Customizable Unit Tags included into reports.
    – Detection of 515 unit application type (Load/Batch/General) & informing about mismatching.
  • Inbuilt Modbus TCP/IP protocol -There is now the ability to connect via TCP/IP protocol without using third party software, making the process of configuration, connection and communication with remote instruments via Ethernet so much simpler. Ethernet connection can be via direct cable, Intranet (LAN) or Internet (Wired or Wireless 3G/4G). The use of TCP/IP communications to remote instruments, now gives the ability for the data in a 515 Flow Computer or Controller to be accessed by DataMod from almost anywhere in the world.
    (Note: Current 515 instruments will require an external Serial to TCP/IP device, however, Contrec will soon release a 515 option card with its own Ethernet connection.)

Contrec take part in local Soapbox Race in raising over £6,000 for Overgate Hospice

The Directors and staff from Contrec, Flowquip and Flowhire recently took part in the local Soapbox race held at our Triangle cricket club. The event saw local individuals and businesses designing and building their own vehicle to take part in the race which raised over £6,000 for Overgate hospice. The vehicle (designed and built by our own management team) must have steering and braking capability and teams are judged on both the time taken to complete the course, along with the creativity of their design and the showmanship of a performance at the start of the race, meaning the team with the fastest time is not necessarily the winner.

It was a great day, and despite our production Director Tom writing off the car on the timed race, lots of money was raised for a great local charity!

The Art of Communication – Modbus

 

Our software engineer Eugene Babenko give us the lowdown on addressing issues and provides some guidance when communicating to Contrec’s 212, 505 and 515 Instruments via Modbus protocol.

 

Contrec customers rarely have issues when connecting their instruments to PLC’s and back office data systems; when configuring Contrec devices our documentation explains simple set up procedures for inputs and outputs. However, even though this is the case when connecting devices via Modbus RTU protocol it is important to pay special attention to the correct master software settings for register number and byte/word ordering for 32-bit data such as floating point values and long integers. The points of attention are:

  • The Modbus.org documentation refers to “one-based” register numbering. However, the addresses that are actually sent in a Modbus command message are “zero-based”.
  • The Modbus.org specification doesn’t define exactly how the data is stored in the registers. As a result, 32-bit data could be (arbitrarily) arranged in four different ways.

Incorrect settings can lead to either completely wrong readings for 32-bit data (which is easily detected) or, in some situations, it can produce subtle and inconsistent readings that look almost as a correct value, but may not update when expected and/or have slight deviation from the expected (displayed) value – this may happen when both register numbering and byte/word order are incorrectly set, so that the data reading becomes a mixture of two adjacent different data points.

The Contrec documentation should be carefully followed on when setting master software. If in doubt, the user should test various master software settings until matching with the displayed value is achieved – most programs for communicating with Modbus slaves have flexibility to be configured for different register byte/word order for 32-bit data and a choice of “one-based” or “zero-based” register numbering.

Further information can be found in https://en.wikipedia.org/wiki/Modbus  article, see below excerpts from the article:

Implementations

Almost all implementations have variations from the official standard. Different varieties might not communicate correctly between equipment of different suppliers. Some of the most common variations are:

What is byte and word ordering?

The Modbus specification doesn’t define exactly how the data is stored in the registers. Therefore, some manufacturers implemented Modbus in their equipment to store and transmit the higher byte first followed by the lower byte. (AE before 41). Alternatively, others store and transmit the lower byte first (41 before AE).

Similarly, when registers are combined to represent 32-bit data types, some devices store the higher 16 bits (high word) in the first register and the remaining low word in the second (AE41 before 5652) while others do the opposite (5652 before AE41)

It doesn’t matter which order the bytes or words are sent in, as long as the receiving device knows which way to expect it.

For example, if the number 2,923,517,522 was to be sent as a 32 bit unsigned integer, it could be arranged any of these four ways.

                                                                                          
     AE41 5652       high byte first        high word first
     5652 AE41       high byte first        low word first
     41AE 5256       low byte first          high word first
     5256 41AE       low byte first          low word first

Confusion about Register Addresses

In the Modbus.org standard documents, holding register addresses are given a prefix of “4” to distinguish them from other register types. For example, in their documentation a holding register at address 1001 is referred to by “41001”. However, the leading “4” is not really part of the address and most programs dispense with this extra prefix, especially when the program context makes it clear that it is referring to a holding register. Also, the Modbus.org standard documents refer to register addresses using “one-based” numbering. However, the addresses that are actually sent in a Modbus command message are “zero-based”. For example, to read register 1001, the address that is actually sent in the command message is 1000.

Confusion about Little-Endian vs. Big-Endian Word Order

Although Modbus.org standard documents provide some guidance for implementing the Modbus protocol, they do not address the question of word order beyond the 16-bit register level. For the 16-bit register values, the most significant byte always precedes the least significant byte (in other words, the register value is transferred in Big-Endian byte order). This is because when the Modbus standard was created in the late 1970’s, most processors used a Big-Endian memory architecture (where the most significant part of a multi-byte value is stored at a lower memory address). However when the need for transferring 32-bit (i.e. 4 byte) values with the Modbus protocol later came about in the 1980’s, Little-Endian Intel processors dominated the PC market so most vendors chose to map the least significant word onto the lower address of the register pair.

This lack of standardization for values larger than 16 bits has resulted in a situation where Modbus implementers have to make an arbitrary choice as to which address of the register pair contains the most significant word of 32-bit values such as IEEE-754 single-precision floats and signed or unsigned 32-bit integers. Most programs for communicating with Modbus slaves can be configured for either register word order.

Product Focus – Batch Controllers

 

What are Batch Controllers?

Batch Controllers are used for the accurate dispensing and measurement of fluids for a variety of industries from food and beverage to truck loading. 

Contrec’s accurate and reliable batch controllers range from the 400 series ideal for Intermediate Bulk Containers (IBC), drum and container filling and food processing to the 515 series instruments, suitable for more complex batching applications.

 

Contrec Batch Controllers

Contrec’s 515 series delivers highly accurate field controllers for the process and petroleum industries. It utilises a common, advanced hardware and the functionality is determined by software which is tailored to individual applications. This allows multiple channels and outputs to be configured; allowing applications such as additive injection, ratio blending, temperature and density corrected batching to be easily configured.

For example, our Batch/Ratio Process Controller (BR01) application is a batch ratio controller for the delivery of two products into a vessel at specific preset (but adjustable) ratios using volumetric frequency inputs. Batch control can operate in preset or on-off modes, while flow control can be set to various loop control modes. It offers single or dual stage control as well as no flow, leakage and overflow error detection. Additionally it has a remote run/stop/reset function. As with all the 515 Series batch controllers the BR01 is suitable for use in control room, field mounting or hazardous areas.

Introduced in 1992, our 400 Series quickly became the industry standard for accurate and reliable flow monitoring and control. In fact, many of those early instruments are still in service today. However, we continue to look at innovative ways to make good flowmeters even better and so our field proven 400 Series has recently received an upgrade. Taking many of the best features of the 400 Series, such as the large LCD displays, rugged reliability and auto run and flow alarm features, we’ve added many more features to the 424 Batch Controller model as standard.

The new 424 Batch Controller will interface to most flowmeters with pulse or frequency outputs. Batch total, flow rate, accumulated total and preset value can all be displayed in engineering units on the large LCD display. The instrument comes fitted with both RS232 and RS485 communication outputs which to allow it to print delivery tickets and also be monitored and/or controlled remotely from the control room.

The 430D Batch Controller, for example, is suited to applications where precise measurement and control of variable batch quantities are required. Batch quantities and calibration parameters are entered via a full 12-key numeric keypad. A bright LED display provides an excellent operator interface even in dimly lit environments.

Contrec has an international reputation for delivering accurate and reliable field controllers. Our instruments continue to prove themselves in the field; years after their installation.
