Used for Siemens PLC such as S7-1200, S7-300, S7-400, S7-1500 and Mitsubishi PLC FX3U, FX-Q Series

The importance of connecting PLCs and terminal IO modules has an important role in collecting data from field equipment. For specific industries such as Oil and Gas, Marine, Chemicals, and manufacturing lines, disconnection will seriously affect the production process, affecting the chain.

Take a simple example, in the field of oil and gas production, on each pipeline there will be sensors that measure pressure, temperature, gas leak directly connected to IO modules and transmit signals to Siemens PLCs. or Mitsubishi in the room controls the current status message. If at any location due to being dragged to the weld, .. leading to high pressure can destroy the pipe, then the transmission of the sensor from the IO module to the PLC requires connection. If so, what if the connection from 1 of the 3 components is interrupted? The consequences will be huge if not intervened and solved promptly.
Understanding the importance that Moxa offers Ring ring connection solution is one of the reliable connection methods used by many large factories in the field of oil and gas. The advantage of having two network lines from industrial switches EDS, when there is a problem from a line, the algorithm will calculate quickly within 20ms of changing other lines and reporting to the control room for engineers to intervene promptly time, ensure production and safety.
The circular LAN model is arranged in a circular pattern. In this case, the cable line will be designed into a closed circle. The signals running around the circle will move in a certain direction.
Inside the ring network, there is only one node at a time that can transmit signals among the system of information nodes. In parallel, the data transmitted must also be accompanied by the address at each receiving station.
The advantage of ring network is that it can extend the network to far away. The number of wires needed to use is also less than the two network models mentioned above. However, the biggest drawback of the main ring type network is the non-closed line. Once the signal is disconnected at a certain point, the entire system will stop working.
The above article aims to ensure wired network connection,
