I have a Step5 PLC, CPU155U, 948 connected to 4 RTUs (ET200M). 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? AttachmentDesktop.zip (203 Downloads) |

Hello What I can understand from ISTACK is : DI Module containing Inout Byte 35 is listed in Input list of DB1 , however the CPU is not able to detect it on Startup. 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 |
