I am sorry because of it is really difficult to understand clarification how tomake sense ofyour message that what you are attached file that kind of a txt file so that I answer the your problem to discuss as long as you have other kind of documents related to it. Also if it is possible, you should give me to take screenshot relevantyour problemsof F-300 CPU in case itcab be used to resolve the trouble quickly.

Then the input modules returned and PLC acquired the safety IO modules again and took them to use. Here the PLC is complaining that it can't read IO from a remote IO module, note that the error message is INCOMING EVENT. Plenty of these incoming events in the buffer before this. This one is the last of those events. Event 10 of 500: Event ID 16# 2942 I/O access error, reading P area, word access, Access address: 665 Requested OB: I/O access error OB (OB122) Priority class: 1 External error, Incoming event 11:05:18.321 AM 12/31/2014 Here the PLC again restores connection to the IO module, notice that the error is OUTGOING EVENT. Other similar messages appear. Event 9 of 500: Event ID 16# 38CB PROFINET IO: station return address of the affected station: Input address: 2023 IO system ID: 100 station number: 5 Log. Basic address of the IO controller: 2041 Requested OB: Rack failure OB (OB86) Priority class: 26 External error, Outgoing event 11:05:18.329 AM 12/31/2014 Here the PLC again restores the safety IO on those missing IO modules to action, the safety inputs in the modules are again read. Note the OUTGOING EVENT. Event 5 of 500: Event ID 16# 78E5 F-I/O depassivated - Monitoring time exceeded at the safety frame detected in the F-CPU Logical base address: 835 F-I/O database number: 934 External error, Outgoing event 11:05:44.140 AM 12/31/2014 (Coding: 16# 78E5 9F00 C47A 03A6 0343 0002) Just to make sure, check the HW configuration of the PLC and check what IO module has the Logical base address: 835. Check if that address is part of the IO modules that the PLC lost connection to. Note: I'm not familiar with ET200PRO PLC:s. This would be my message if the PLC is 300-series PLC. (Sidenote: There appears to be a new firmware available for the PLC but the firmware does not appear to contain anything critical) Edit: The diagnostic buffer message says the PLC is 6ES7 154-8FX00-0AB0 http://support.automation.siemens.com/US/view/en/51677565 Perhaps the S7-200 forum would be better suited for this topic
