It depends on what you want to communicate and the protocols you want to support. The BRX PLC (Do-More) also has the above protocols that you can read, but it can also be used to collect data from Ethernet IP, Modbus TCP, Modbus RTU, and MQTT. Both PLCs are available from automation direct com. It can use Modbus TCP and Modbus RTU as masters to read information from other controllers. We have a comprehensive line of industrial Modbus gateways that allow you to pass data from devices on networks that use over 30 different protocols. Recently I was asked to demonstrate communication between a BRX PLC and Click PLC using Modbus RTU.
#USE CLICK PLC AS A MODBUS SERVER SERIAL#
It can be read from Ethernet IP, Modbus TCP (Ethernet), Modbus RTU (Serial) or any customized Serial communication. Yes, you can find PLCs that will work with several universal protocols.Īs mentioned the Click PLC would be the least investment.
