Customer Solution: Industrial Brewery Production and Diagnostics

Posted by

A major American brewing company was in need of a solution for its production facilities that could network multiple production processes together  and be able to withstand temperatures in excess of 140°F without failing. Multiple controllers and production machines needed to be seamlessly connected, and it had to work flawlessly.  After extensive research and testing, the company chose to deploy Comtrol’s DeviceMaster® UP.

Loaded with Modbus/TCP firmware, the DeviceMaster UP provides the brewery a flexible, easy-to-use and highly robust solution.  Controllers include SCADA systems communicating over Modbus/TCP and PLCs communicating via Modbus/TCP, serial Modbus/RTU or serial Modbus/ACSII.  The production machines communicate via ASCII data, Modbus/RTU or Modbus/ASCII.  Further complicating the situation, the ASCII data machines need to communicate to each controller independently.

The DeviceMaster UP seamlessly networks the controllers to the production machines. The automatic Modbus protocol conversion functionality enables multiple Modbus controllers to communicate to the serial Modbus machines.  The industry’s first command/response mode enables multiple controllers to independently communicate to the ASCII production machines.

Ethernet Over Fiber-Optics: As clear as glass!

Posted by

As the demand for Ethernet connectivity increases in the market, so do the demands on Ethernet connectivity.  By transmitting Ethernet signals over fiber-optic cabling, users are able to extend the distance Ethernet signals will reach, protect against external Electro-Magnetic Interference (eliminating internal), and shield products from electrical surges.  All in all – by transmitting your data through light in a glass cable, fiber-optic connectivity is a great way to get more out of your Ethernet connections!

While the sales pitch on fiber above certainly sounds appealing, there are many aspects to consider during a migration to fiber-optic connectivity.  In order to select the best fiber optic connectivity solution, we must address:

1. Type of fiber-optic communication
2. Bandwidth
3. Fiber-optic connection type

Relating directly to these concerns, users must ask themselves

1. Type of fiber-optic communication

How do I want my data to be sent over fiber?

fiber-optic communication Fiber-optic communication is available in two different forms: Single-Mode and Multi-Mode.  Single-Mode, generally associated with longer distance capabilities, provides a hyper-efficient mode of transportation for the data-carrying light signals.  Multi-Mode fiber, while less expensive, is a less efficient method of fiber transmission.  As data travels across Single-Mode fiber it will degrade less than it would over the same distance with Multi-Mode fiber.

Furthermore, each fiber strand is designed to support a specific wavelength of fiber transmission.  Wavelength, measuring the distance between successive crests of a light wave, also influences efficiency and distance fiber can be transmitted.

In order for the handlers to be automatically guided through a warehouse with precision, cameras attached to the vehicle itself must be as accurate as possible.  These cameras also need to interact with a PLC running Modbus TCP/IP, which writes and ready data to and from the cameras’ power for efficient battery usage.

As shown to the right, five cameras needed to communicate with a PLC on each handler.  Ward Systems decided to use Comtrol’s DeviceMaster® UP 4-Port and a daisy-chained DeviceMaster UP 1-Port to provide support for each camera.  All of the cameras are directly connected to one network switch, which is then connected to the DeviceMaster switch, which is then connected to the DeviceMaster UP 4-Port and DeviceMaster UP 1-Port.  The PLC is also connected to the network switch, along with a detachable PC used for configuration and programming.  An RFID reader and a custom PCB board connect to the two remaining ports on the DeviceMaster UP 4-Port.

The cameras on the pallet handlers support raw/ASCII data, while the PLC supports Modbus TCP/IP.  Comtrol’s DeviceMaster UP enables communication between the two different protocols to make the entire system a success.

Comtrol’s DeviceMaster UP is designed to provide innovative PLC to device connectivity.  The DeviceMaster UP provides EtherNet/IP, Modbus/TCP, Modbus RTU/ASCII, and PROFINET IO connectivity to a wide variety of devices.  A highly advanced raw/ASCII device interface functionality simplifies PLC programming and ensures robust operation.  These features greatly simplify connecting devices such as bar code scanners, RFID readers, weigh scales, vision systems, printers, encoders and sensors to PLCs.  The DeviceMaster UP’s many unique features provide connectivity options and flexibility not provided by other gateway products.

DeviceMaster® UP Plays Key Role in Oil Pipeline Monitoring

Posted by

System critical automation processes, such as monitoring oil pipelines, can be very demanding on a communication infrastructure.  Performing reliable real-time communication over long distances from multiple Modbus masters to large numbers of remote devices can be a major challenge.  The communication equipment must be highly flexible and robust to perform such a task and the DeviceMaster UP meets that challenge.

oil pipeline monitoring device server modbus

When a major oil company asked Comtrol to help them upgrade their current pipeline infrastructure, Comtrol provided a solution with the DeviceMaster UP running our Modbus Router firmware.  Highly flexible and robust, the Modbus router provided the required communication needs.  Multiple Ethernet and serial Modbus masters were connected to multiple serial Modbus slaves.  The flexible Modbus routing capabilities, the wide operating temperature range, and the robust operation provided by the DeviceMaster UP proved to be the perfect solution.

the process of transporting oil from the oil well to the refining plant must be monitored very closely in order to ensure the total overall health of the system.  Sensors all the way along the length of the pipeline must be constantly checked to ensure safe flow rates, pressure levels and temperatures are maintained.  When a problem is detected, it must be quickly dealt with to avert a possible shutdown or, in worse cases, a catastrophic failure.

Satellite links are used to connect the control center where the SCADA systems reside, to remote Ethernet networks.  It is at those remote Ethernet networks where the DeviceMaster UP provides simultaneous connections between both Ethernet and dial-up modem-based serial Modbus masters to the Modbus slave devices.  In this way, all the individual remote networks, or subnets, are combined to form one large network.  Comtrol’s Modbus Router provides the required real-time connectivity between the Modbus controllers and devices on the network.

  • Highly flexible with many Modbus connectivity options
  • Masters: Modbus/TCP, Serial Modbus RTU/ASCII, and Modbus RTU/ASCII over Ethernet TCP/IP
  • Slaves: Modbus/TCP and Serial Modbus RTU/ASCII
  • Automatic protocol conversion and routing
  • Turn serial Modbus masters into Modbus/TCP masters for network wide connectivity
  • Connect Modbus masters to Modbus devices anywhere on a network
  • Simultaneously connect multiple Modbus masters to individual slave devices

Modbus/TCP Master-to-Master Communication

Posted by

A large oil and natural gas platform in the North Sea was expanding their facility capabilities by adding a massive system module (over 1.5 million lbs) to the existing platform infrastructure.  In order for the two systems to communicate seamlessly with one another, the proper communication channels needed to be established.

Control systems on each structure were configured to communicate with each other through a serial Modbus RTU RS-232 or RS-485 channel.  However, the Modbus device configuration on each side was designed to communicate as a master, while traditional Modbus communication takes place between a master and a slave.

Each structure’s respective developers had invested substantial resources into their control systems, so the systems integrator needed to find a way to overcome this obstacle by converting one configuration to act as a slave in the most cost-effective way possible – or by making two Modbus master devices communicate with one another.  Many industry experts have expressed that master-to-master Modbus communication is impossible, but Comtrol had already developed an innovative solution to make a Modbus master communicate with another master.

modbus master to master connect DeviceMaster gateway

The systems integrator assigned to this task researched master-to-master connectivity and ultimately discovered the DeviceMaster® UP’s capabilities on a respected online forum.  Hesitantly beginning the application, the integrator was highly satisfied with the end result.

As seen in the diagram, Comtrol was able to fix this integrator’s problem using the DeviceMaster UP 2-Port 2E Modbus gateway running Modbus/TCP firmware.  Information coming from each control system/Modbus master device would be routed through serial Modbus/TCP firmware.  Information coming from each control system/Modbus master device would be routed through serial Modbus RTU into the DeviceMaster UP.  Internally, the firmware essentially provides a Modbus slave to respond to each (external) master’s commands.  The slaves are then internally linked to each other to complete the communication process.  Without viewing the internal configuration, the end user only observes that the DeviceMaster UP enables a successful connection from one master to another.

The Modbus/TCP firmware is the original DeviceMaster UP Modbus application.  It has been designed to provide great flexibility for connecting both Modbus serial slaves and Raw/ASCII devices to a variety of Modbus controllers and applications.  Such advanced Raw/ASCII options as filtering, command/response mode, peer-to-peer Modbus communications, and simultaneous connections to multiple Modbus controllers and/or Ethernet TCP/IP applications make the Modbus/TCP firmware the flagship of all Modbus gateways.
