Can I use a vision plc as both a modbus master and a slave

Recommended Posts

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.

Thanx

Allan
