So, a customer has an S1 and several EB2 racks in different panels. Each panel has its own HMI and there is a control room PC running a different HMI.This morning the program got stuck at a particular place in the opto script (below). I’m trying to figure out why it’s getting stuck but I can’t figure how it works in the first place. It looks like it’s setting a variable then waiting for that variable to reset. I’ve searched the S1 application and can not find that variable anywhere else. I’ve tried searching the PACisplay HMI and can’t find it there either. What’s going on? If I can figure out how this is working, maybe I can figure out how to prevent it from getting stuck (variable not resetting).// send record for current batch to databases_cp_hmi_message = “Downloading Batch Information”;i_cp_download_batch_to_db = 1;DelayMsec(500);while(i_cp_download_batch_to_db) DelayMsec(100);wendP.S. The customer reports that the problem can be resolved by restarting the control room PC. How does make sense?
