Hello endigual: This might surprise you, but that is the way all couples work in a Siemens configuration: PN/PN coupler, DO/DP coupler... They are bridges between different branches of networks, as as such, all that a CPU sees is data in it's own memory areas. Outputs from CPU1 to the coupler are written to the memory inputs of CPU2; inputs from the coupler to CPU1 are data transferred from CPU2. See this document for a more precise description: PN/PN coupler, Getting Started: https://support.industry.siemens.com/cs/us/en/view/88737127 Please follow the suggestions already posted by our friend Hati. Hope this helps, Daniel Chartier |

Thanks for the information, now I understand. But I have another doubt because "Hati" says that the function DPRD_DAT is not the instruction to use with a DP/DP coupler. But I try to use it and it works correctly as the attacched image that i sent to you in the first post |
