Dear ahmedmae94, The highest station address should be the same in CPU and PP17. At this moment in CPU is 31 and in PP17 is 126. Change it at one side. Best regards, Wizard |

Look at - You chose "Data area type: Marker byte" and "Configuring data block: 2". I thing this must be "Data area type: Data block" and"Configuring data block: 2" or"Data area type: Marker byte" and "Marker byte - some number, for example 100". You can check this in manual - page 18. Hope this helps. regards |

Hello Could be the reason in hardware? Would you check again cable and connectors? regards |
