Dear sirs I have 1 suspected failed channel on module SM321 (Model : 6ES7321-7TH00-0AB00). ET-200 configuration. So, I need to replace new module. Can I replace it online without any affects to normal operation ? Should the firmware version of module should be taken care before replacing ? pls refer to configuration attached Thanks much

Hello kietnt81 Good news first: Yes, you can in general replace Signal modules during operation with an S7-400H system. Wether or not this will affect your process is something I can't say without more info. The first question is if your supected faulty DI card is a so called "single channel switched I/O" type (which your drawing seems to indicate) orif it exists a redundant type(the latter is better as the redundant "brother" of your suspected faulty DI cardmeans the H system continuesto get all DI inputs from the still functioning DI card). Anyhow, I suggest you download the SIMATIC Fault-tolerant systems S7-400H manual and study especially chapter 13 and 16 to work out what you need to take care ofand revert back here with more questions if need be (and provide more details too please). I hope this helps |

Hello kietnt; What you want ot do, Siemens calls "Configuration in Runtime" (CiR). The basic manual for this is found here (don't worry, it is very short): SIMATIC STEP7 V5.5 Modifying the System during Operation via CiR Check the first chapter to see if you meet the hardware/software requirements, and chapter 4 to see the procedure with an ET 200M. Hope this helps, Daniel Chartier |
