Answer / ashish namdev

Operation station system no have any program (programming built in Engg. Station Only which is a server also)

but operating station system is connected with same network of plc/Dcs through Ethernet or other.

than that station has a SCADA software which is connect it to server system station through IP protocol.

than we can access or give command through Operating station.
