Thanks, Best regards, Ni If you need pulse train , you check the CPU's internal clock memories which configured in H.W config.For 1 min pulse train you need to use to consecutive timer (Oo delay timer and off-delay timer) Timers are differentiated by type of activation and their response to input .It depends on your applixation which timer would help. Check the timers in the instruction set available in LAD-FBD-STL editor, use step7 online hep for more information. Ask your question here in case of problem. regards

Define Clock memory byte in CPU hardware Property. For example MB0 then M0.5 will be 1 sec pulse. for 1 min pulse you have to make logic.

For example, configure OB32 execution time to be every one second (From HW configuration) and then you can increment a memory word every OB32 scan. This can be better than timers if you want long time calculation, because timer has a limit for its set value. This is better also because you can take the value of time and easilyuse it to do calculations.
