Hello isteak I fear your current "delete this, download that" trial and error troubleshooting approach is not the most effective one and suggest you go backbasics. What I suggest you do is essentailly what jklm's already advised you to do, but to begin with, here are a few observations: OB23 is NOT the root cause of the CPU Stop, but simply a reaction to theproblem and being called by the S5 OS when a Timeout (QVZ) in the user program takes place (e.g. during direct access to I/O modules, see the 928B manual for more on it and search for "OB 23" related entries). Someone will have deliberately programmed a STOP command into your OB23 to put the CPU into a Safe State when a QVZ error occurs in the user program. Deleting OB23 will as such prevent the CPU Stop, but not eliminate the real problem nor help you in determining what the root causeis. To find out what the real problemis I suggest you do the following: 1.) Have the completeprogram in your CPUand give it a Cold restart 2.) Go back into the BSTACK (presuming it still crashes) which gets you into the first Block stack level where OB23 is listed (ref. your screendump in atttachment) 3.) Use <F7> "Continue" to go down one level in block stack. This will show what block was active before OB23 was called (Take a screendump of it). Place your cursor in the bottom half of the screen and press <F2> "Edit". |
