Local error handling

3.2.13.1

Handle errors within block

Procedure
Unlike the CPUs of the S7-300/400, CPUs of the S7-1500 go to STOP with errors much less
often. If an error occurs, it is entered in the diagnostics buffer of the CPU. You avoid the
CPU STOP by using local error handling at each block. You should preferably enable local
error handling during development of the user program.
