compoway/F communication

4 posts in this topic

Hi all I'm new to OMRON PLC's i have CJ2M cpu& SCU31V1 and K3HB digital indicator(Picture1). the only protcol supported in this case is compoway/F. i couldn't communicate or read PV from K3HB to PLC. 1/code: this indicator doesn't have a smart FB like the other smart I/O has (temperature E5 Zn...), so i have to build my own code i tried with PMCR2 instruction and i got the request frame:(Proj1-NewProgram1-Section1.zip) (01E1 0262 0019 0200 0000 0000 0001 0001 00C0 0000 0002 0000 0000 0019 0300 BCC)HEX from the cpu to SCU what i've missed? 2/compoway/F protocol for the K3HB: is it integrated or do i have to create my own protocol using cx_protocol how to trace the frames send & receive trames? Configuration why i couldn't integrate the K3HB into Compoway/F Network on the cx_integrator ?

I would use PMCR. PMCR2 is more complicated, and is not needed unless you need more than 8 PMCrs running at the same time. Try this code. I assumed Unit # 0 for your SCU. Panel Meter Read.cxp
