Is modbus protocol safe for carrying out peer-to-peer sharing of data between 2 controllers?
I have a requirement where a PLC and another controller are involved. The controller will control the process through hard-wired I/Os; PLC is required for monitoring and providing sequencing to the controller.
Is it safe to implement this using modbus?
I have come across recommendations saying modbus should not be used for such applications where control data is shared. Is it true?
