Hi all!
Can you help me for adding my OWEN PLC110-60 to OH3 based on RPi3?
on my PLC i have slave1 on port 503 with 3 dword VAR
i added modbus tcp slave
host 192.168.144.8
port 503
id 1
next add poll
start 0 len 6 type holding
but this poll not work:
Error with read: org.openhab.core.io.transport.modbus.exception.ModbusConnectionException: Error connecting to endpoint ModbusTCPSlaveEndpoint@38a6454d[address=192.168.144.8,port=503]
i installed another programs to test modbus connection,
on my Rpi3 modpoll working perfectly, and collect all data from plc
and on pc modbus scanner give all data from plc slave
You now have two masters online! PLC 110 operates in Modbus Master mode! And openHAB works in Modbus Master mode! Conclusion - set PLC 110 to Modbus Slave mode! Correct me if I’m wrong!
