The Modbus/TCP firmware has been made to provide flexibility and functionality with emphasis on raw/ASCII device support. Its feature-rich platform is also able to support both slave and master serial Modbus devices.
Modbus/TCP Gateway Highlights:
The Modbus/TCP firmware is the original DeviceMaster UP Modbus application. It has been made to offer great flexibility for connecting both Modbus serial slaves and Raw/ASCII devices to many different Modbus controllers and applications. Such advanced Raw/ASCII options as command/response mode, peer-to-peer Modbus communications filtering, and simultaneous connections to multiple Modbus controllers and/or Ethernet TCP/IP applications make the Modbus/TCP the flagship of all gateways.
A large oil and natural gas platform in the North Sea was expanding their facility capabilities with the addition of a massive system module (over 1.5 million lbs) to the existing platform infrastructure. In order for both systems to communicate seamlessly with each other, the correct communication channels had to be established.
Control systems on each structure were configured to talk with one another through a serial Modbus RTU RS-232 or RS-485 channel. Modbus device configuration on both sides was designed to communicate as a master, though traditional Modbus communication takes place between a master and a slave.
