Hello all,
I am developing HMI screens for a Wastewater Treatment Plant which is using Modicon M580 PLCs that are running Unity Pro XL version 8.0. In Wonderware, I am creating a Network Status Screen which will display the overview of the network and alert the operator when a communication failure has occurred. I was wondering if anyone experienced with Unity Pro knows of a communication system bit or has any advice for communicating through the DAServer to determine a Comm. Failure has occurred. The network is currently through standard ethernet/TCPIP and there are 4 Panels that will need to be monitored. I have created a heartbeat block on each PLC which sends a pulse every 3 sec to the DA server. However, I am not sure how the other M580 PLCs on the network can access this pulse value when the DA Server is down?
Thank for any and all advice!
