Hi, The OB will not work in central rack and there are also limitations due to safety. But in general, the function "configuration control/option handling" could be used. Configuring standard machines in TIA Portal (configuration control)What should you watch for with configuration control (option handling) with fail-safe controllers S7-1200 and S7-1500?regards sancruz |

Hi, it depends on where the modules are used. Pull or plug of modules OB - (OB83)-> "Regardless of whether you have programmed this OB, the CPU changes to STOP mode when any of these conditions occur with a module in the central rack." Rack or station failure OB - (OB86)-> only called due to "failure or communication loss of a distributed rack or station", so not for modules in central rack Diagnostic error interrupt OB - (OB82)-> for diagnostic events/messages, but doesn't prevent from goint into stop mode if module is missing OB121 is not available for S7-1200 Which organization blocks can you use in STEP 7 (TIA Portal)regards sancruz |
