Hello to all,
In process control system we have three main control system as DCS, ESD and F&G system. The ESD and F&G system connected to DCS via serial data link as Modbus (RS485).
In addition to mentioned link, in our architecture we have another communication between ESD and F&G system with DCS connected directly to DCS highway network (monitoring network) via industrial network.
My question is: What is the purpose this connection? and does it need to consider beyond serial communication link with DCS? As I know that communication between DCS with ESD and F&G consider to collect and monitor status of ESD and F&G signals in DCS HMI.
Please explain the purpose of the other link.
Thanks in advance.
