Software installed SICAM SCC V7 SP2 Upd2+Upd6 Protocol used is Modbus Slave for connectivity to a Modbus Master device (PC) and DNP over IP Master to the Protection Relays. Both softwares are on the same machine. 2Nos. SICAM PAS have been configured in redundant configuration. PC1 will be in parrallel with SICAM SCC on the same machine PC2 will be in parallel with SICAM SCC on the same machine We have PC3 with only SICAM SCC which will connect redundantly to PC1 SICAM PAS and PC2 SICAM PAS Now, what is really strange is that about once every month all three HMIs (SICAM SCC) crash with the following errors (attached). The crash happens at exactly the same time. Restarting the WinCC runtime does not solve the problem. You have to restart the PC. We are not using Secure Communication as shown in the Error Report. Does redundancy on PAS have anything to do with this? Have you seen this before? The substation is live and i want to be sure. Do you think the attached Sales Information has anything to do with this crash? We have the exact same setup in another substation with the same project file changed a little bit to customize to the substation but there is no Modbus connection there and there is no crash. I have checked the Archive Size - we have a 32GB solid state hard disk on a IPC647C Time period of all segments has been set to 1year Max size of all segments is 1000MB The substation is remote (Northern part of Canada - Saskatchewan) and i dont want to upgrade PAS version unless i am sure that this is the cause of the problem I appreciate your support or any tips on whether you have seen this before?
