I have been trying to use this program with this card: https://mikroelectron.com/Product/Modbus-RTU-4ch-Relay-12v-RS485-Module-4-Input-Optocoupler-Isolation/ but it does not work. What could I be doing wrong or if it definitely doesn't work for this type of cards.

Hello @cofhal. For answer to you need more information.

  1. Connection scheme and modbus params.
  2. Operation system where execute OpenModSim.
  3. Serial port log received from any serial port sniffer program.
