The CPU goes to stop and one of the ET200M stations gives BF. The ISTACK is attched, but I'm no expert in Step5. How can I trace the problem? Attachment Desktop.zip (461 Downloads)

Is this inputbyte available, mentioned in DB1 ? Something wrong with remote Island containing this inputbyte ? Kind regards, BV

Pl check the module / connection to the rack containing this module. For more details pl download and read the Manual : S5-155U CPU 948 Programming Guide Check out Chapter-5 - Interrupt and Error Diagnostics Hope this helps Cheers Navnag
