Re: [foxboro] Connecting two PLC through Plant Network

It's a dangerous practice to run process control over the general purpose plant 
network. Run a separate network or secure radio link. Using the plant network 
leaves you open to intended and non-intended unauthorized access to your 
production system. Always connect process network to plant network through an 
application gateway, firewall or secure router.

Subject: [foxboro] Connecting two PLC through Plant Network

We have two PLC separated by a long distance and there is a purpose to connect 
both over the plant network. The objective is that one PLC has to tell the 
other to do something, so the connection is not for diagnostic. It seems that 
the idea is not good because the plant network is not the right path for 
connecting two plc to work together but I do not have any paper, standard or 
experience of people who have done this before.


Any comment or idea to share will be greatly appreciated.
