If we are talking about STEP 7 basic package for SIMATIC S7-300/400 CPUs , normally extra checks on your codes are not mandatory and you can download your modified codes to CPU with your own responsibility.CPU never asks your permission to enter in STOP mode because of programming error .There are some routine check before you implement your change and finalize them.Also some minor warning you receive while editing your program (attached file).To avoid entering CPU to STOP mode the following OBs are suggested to be downloaded to CPU and react to cause of error and possibly shutdown part of plant . Which organization blocks do you need for error handling in STEP 7 V5.5? |
