  1. Thanks for the reply, yes my sample projects attached work great, I have 2x sambas on my desk for testing, i split the registers up like that to simulate reading from multiple slave devices across various registers. i have done as suggested with SI103 etc that works great, and reconnects after a short period
  2. Hi there, I have to update program on a site where we already have 2x samba 43 in place, I will need to poll some modbus values and show them on the displays from 4 RS485 devices, - VSD and soft starters, these will all be on a RS485 to TCP gateway, in my complete program I have made a separate working example of what i'm trying to do, by using 2 spare sambas i have, as a master & slave combo i just wanted to know if its the best practice way of doing it when polling the 24 to 30 different values needed I am also curious about the settings to do with SB168 Link lost a
  3. Hi there, I have an installation with 2 softstarters that use rs485 modbus and an ethernet gateway that is the master of that ring I can send and receive all data needed using Modscan32 over TCP connection on laptop to both softstarters so far i havent been able to get a response from the softstarter when using the PLC - error code 5 and 4. SO I guess the question is, does the slave ID get sent along with the 'message' when using modbus ip function blocks, so the gateway knows where to forward the message?
