to libmodbus
Hi,
I installed libmodbus-3.1.6 and I am testing TCP modbus, using local TCP client server works fine, but I failed to run a TCP client to read a remote TCP modbus server registers, the modbus_strerror(errno) was "Target device failed to respond". Are there any other public TCP modbus testing server available I can test with?
Thank you.
Kind regards,
- j
