I have an Omron CQM1H-CPU21 and a NS8-TV00B-V1, I have followed the manufacturer's spec on how to set this up and all I got is the HMI is trying to talk to the plc because my parallel light flashes time to time so it's trying to talk but the PLC is not talking back.
In PLC ''Host Link Port'' Mode set to ''NT Link''
In PLC ''Peripheral Port'' Mode set to ''Host Link''
on PLC ''Dip switches'' 1,2,4,6,7,8 OFF 3,5 ON
In HMI ''COMM.'' Serial Port A, set to ''NT Link 1:1''
Com connector config, ''SD2 to RD3'' ''RD3 to SD2'' ''SG9 to SG9'' Plc side, ''RS4 to CS5''
This is all the info.
