So you cannot change it from inside the program, and you must compile and download (in STOP mode) any changes in the configuration. It can't be done on the fly. Now, may I ask what kind of project you were planning to have this requirement? Hope this helps, Daniel Chartier

This Module provide such a function: CP 342-5 -- How can you change the PROFIBUS address or the operating mode of the CP 342-5 in running operation? Best regards Sabine
