Dear All,
I could not get the results with modscan software to test the Modbus connection for the digital relays. The modscan software says "Modbus message timed out". I have connected the LAN Cable (CAT 6, Untwisted pair) to the RS-485 terminals (Ground, A-, B+). Here is what I have done:
Physical connection:
1. Lan cable (with RJ 45 connector and all the 8 cores connected inside the RJ 45 connector) connected to TSX CUSB 485.
2. The other end of LAN cable connected to the relay RS-485 terminals (ground, A-, B+).
Here, Core No: 8 connected to Ground
Core No: 4 connected to B+
Core No: 5 connected to A-
3. USB connection of TSX CUSB 485 connected to PC
4. The rotary switch of TSX CUSB 485 is set at position 3 (other direct)
Software setting:
All the parameters are matched for the modscan software with the digital relays (Baud rate:9600, Parity: Even, Data bits and stop bits settings not available to set in the digital relay but set as 8 and 1 respectively in modscan software.
