Simple project that demonstrates a Modbus device.
Initially, the simulator only supports simulating a TCP device.
To run in docker:
docker run -it --rm -p 502:502 --name devicesim nmodbus/devicesim
To specify the port:
docker run -it --rm -p 1000:1000 -e "DEVICE__PORT=1000" --name devicesim nmodbus/devicesim
To run UDP:
docker run -it --rm -p 502:502/udp -e "DEVICE__DEVICETYPE=UDP" --name devicesim devicesim
