Hllo dedalos; You can do exactly that with the LED isntrution. See the screenshot an links below. https://support.industry.siemens.com/cs/ww/en/view/109773506/124464984971 Hope this helps, Daniel Chartier |

hello dedalos; Could you show us your hardware configuration, indicating the module from which you are trying to read the LEDs and the hardware identifier you are using for the LED instruction? From the link to the Stp 7 v16 manual suggested abce: "The HW identifier of the CPU (note: also true for the I/O modules) is made known to the "LED" instruction through parameter LADDR" Hope this helps, Daniel Chartier |

Hello dedalos; What is more interesting would be the hardware identifiers of each of these modules, and the LED instruction calls you are using, to validate you are using the hardware identifiers in the LADDR parameter... See mopS04's reply in this discussion: https://support.industry.siemens.com/tf/WW/en/posts/tia-hardware-identifier/230438 Hope this helps, Daniel Chartier |

I'm sorry, probably I did not read carefully your previous answer, I attach the plc code and hw-id view |
