ok but the costumer do not want new wiring. its all ways possible to enable the CLR signal of PTO drive , instead of relay . |

yes first this is 265 and not 256 . then when trying to activate it , it shows an alarm of HW_ID . |

Write a 0 to "(MC_Power Instance Datablock)".Enable in the interrupt. I learned these tricks from https://support.industry.siemens.com/cs/document/77467940/sinamics-v%3A-controlled-positioning-of-a-v90-with-s7%E2%80%911200-via-the-pulse-direction-interface-with-hmi?dti=0&lc=en-WW which has to be the absolute worst example for starting engineers since ALL of the commands are generated in the HMI writing to the instance datablocks (Oh look how clever we are). |

Jeff, this is a brilliant share! I have looked through the provided document quickly and find some descriptions from page 50 that may be helpful. IMO there are much information in this document. I agree with you on the HMI >> DB comment.... if ever you have time - look at the program application for V20 to S7-1200 over Modbus..... ouch! I doubt that the calling of the bit in the interrupt will help.
