Modbus Different physical interfaces can be selected for different connection schemes, RS422, RS485, RS232. All interfaces are electrical isolation
Away. And the redundant operation is realized by two redundant field controllers.
Fi8i0f card is a triple can bus protocol interface card (rate 1mbd) used to connect industrial ial “conventional process control station
The i/0 protection unit of the PS is used to receive process signals from the rack mounted i/0 modules supported by the PS. Each field controller PS can only be configured
-Block fi810f card. — The two fi810f interface cards on the redundant PS. can be switched redundantly.
