The communication is sometime stopping to work (some items are blinking from grey to normal every 5s) It seems to be related to the fact that PLCSIM is overloaded: As soon as I start some online jobs with STEP7, it is getting worse. It's really disturbing as I can not test scripts associated with WinCC, which are interrupted by this loss of communication. My supervision program is using a lot of tag in the PLC (about 5000. I am using STEP7 v5.4SP2, PLCM SIM 5.3 SP1, WinCC v6.0 SP4. I have already read the topic in the FAQ but I've not seen any differences with my actual configuration. If any ideas to fix the problem... Regards, Kramps
