Thanks Disty, Just what I needed. the Omron manual numbering system is a bit cryptic and it takes hours of trawling through them to get the info I require .......... or is it just me :)

Hi, Is there any one stop shop for manual downloads for Omron. We are extending a discontinued PLC type, CVM1-V1 CPU11. The cards we are using are output cards 3G2A5-OC224 and 244. I cannot find manuals on any Omron site for old PLC systems. Any ideas? Thanks.

yes Bob, I'm scaling the analog inputs for display on SCADA and scaling setpoints from SCADA for control etc. It appears the scaling function is not available in the processor I'm using.

Hi guys and gals :), I am working on a CVM1-V2 processor. The programme as written uses the APR(142) function for scaling. I am confused as to the way the data is entered: - Example; The intention is to convert 0 - 100% (BCD) to 0 - 4095 (Hex) The control word used is nD290 with #4000 moved in to it. The data moved is as follows; #64 to nD291, #0 to nD292, #64 to nD293 and #FFF to nD294. This appears to function correctly, but if the manual is to be followed it would be like this; #0 to nD291, #0 to nD292, #64 to nD293 and #FFF to nD294. What am I missing or is there a quirk with this function? Ta
