I am using AB-7800 to communicate between a profibus network to DeltaV ethernet network and I have 3 questions regarding this:
1- which status/Control word should be enabled to monitor the Ethernet connection? the word in the Ethernet side or in the profibus side? as shown in the below two pictures.
2- What is the difference between Enabling the control/status word in Profibus (Master) side and enabling it in the ethernet (adapter) side ? I want to understand if enabling it in the ethernet side means sending status of the ethernet network side to the profibus side? I do not really need that since DeltaV is the main control system
3- when I enable the Control\Status word in the Ethernet side , the Profibus network stops working and shows Red light in the MS led on the gateway front , why is that?
