Hello, This is because of using OB100 (this is a restart OB and is run when the CPU is restarted (warm start)). In this OB, the first communication trigger is enabled with marker 0.3 "START-UP".This bit after that start let's say "communication". In case if you build connection like this FAQ http://support.automation.siemens.com/WW/view/en/29737950 Am I right? Best regards, Hristo Mihalev |
