Hi all! Thank you for your time. I'm having a problem in a CPU AS400 with random program failures registered by the diagnostic buffer. The strange thing is that the guilty FB is not called by the user program as far as i can see. (There is a call on OB1, but it isn't enabled) Is there any Siemens block that calls FB117? Is there any Process on the CPU that calls FB117 even if this FB is not called on the program? Thanks! And my best regards Attachmentdiag.zip (83 Downloads) |

Hi hdhosseini! Thanks for your reply. 1- right 2- See in attachments (LAD view and STL view). I've put a M after the AND in order to check if the block was executing, even if it was no possible.... guess what. This morning i found the M is setted. Obviusly, i used a M that is not used on the program. 3- That was already checked, the "GO TO" button takes you to the FB117. Is a Siemens FB, so you cant read it. 4- what else i can give you? :) 5- I assume one of the variables connected at the FB117 inputs is the problem of the FB. But that is not the real question. The question is: Why the FB117 is executing? I'm very grateful for your time!! Fede Attachmentdiag.zip (68 Downloads) |
