Colleagues, help me!
The situation is as follows:
On the Rackbus RS-485 hang 10 mass flowmeters E+H Promass 63.
Communicate with them on a ControlNet network via a garland
of modules E+H ZA377 -> ZA672 -> FXA675
The controller stopped seeing ZA377, the other two groups Flex-s, are seen hanging on ControlNet and functioning normally.
Replacement of modules from Endress+Hauser have failed.
ControlNet cable tested switching over to another node on the network - a cable is not defective.
Experience with the Rackbus RS-485 and the modules of the E+H I lack.
Do I need any pre-flash of these modules, in addition to installing the switches before turning to the work?
Can anybody share the following documentation:
