Hi,
I have a question related to communicaton to Ronan annunciator panel and Schneider BM85 congregate Modbus Port speed limitation.
I have RS-485 twisted pair daisy chain network which contains 9 GE Multilin Relays and 1 Ronan Series X11CA Annunciator. They are connected via F485F media converter to BM85 port. BM85 is connected to MB+ network. I use Quantum PLC (MBP_MSTR)to retrieve a data from above relays and annunciator. All the relays respond on FC 3 except annunciator. When I use MDbus (Modbus simulation software), I can communicate with all the devices including annunciator. Acting as the slave I have analyzed type of the requests coming from PLC to relays and annunciator and could not find any problem. I am trying to isolate Annunciator on separate MB85 port as the only slave but I heard that there is some congregate limitation on BM85 Modbus Port speed. (throughput). Please if you have any experience with any of these 2 topics to reply on this message.
Thank you
Nandor Farkas
