asabiski Posted July 30, 2020 Report Share Posted July 30, 2020 Boss and I were talking and we have a customer that may want to use a plc as both a master to a temperature controller and a slave to another display/plc. Hypothetical at this point, but can I use a vision plc as both master and a slave? Desire would be to do RTU (RS485) at this point but IP might be possible.
