TCP/IP Primary and Secondary Network indication in PCS HMI
The plant have two way of netwrok TCP/IP primary and secondary(wireless) network for the CSN(Client Server Network) and CN(Control Network). sometime the primary network down due to some reason and secondary network takes the control. there was no indication that the system works in secondary network right now, unless we open the network manager application of hirschmann to check the network status. we are using Hirschmann network equipments(switch, wireless and other)
1. How can show indication in 800xA that currently this controller network works with primary or secondary line?
