Good Afternoon All, I have managed to sort the previous issue by using the Systemfunction "SetConnectionMode" as suggested. I now have another problem, my HMI will communicate fine with each 3rd party device individually, but if I try to use them together it will only communicate with 1 device (I have tested this and it's actually the 1st device to be connected, i.e. if I connected device 2 then device 1, only device 2 will communicate). Does anybody have any experience with using a comfort panel with multiple slaves? I have checked the addresses, and all is ok. I think it is something to do with the HMI trying to communicate with both devices at the same time rather than waiting for 1 to complete? Similar to this: https://support.industry.siemens.com/tf/WW/en/posts/modbus-rtu-multiple-slave-reading/ Thanks as always for your help. Kind Regards Carl ------------------------------------------------------------------------------------------ |
