Scale an output

I am looking to scale an analog output for an electo-pneumatic transducer. I want to have an HMI input determine what pressure to run the process. I'm using a DL-06. Any suggestions?

roboteacher, I'll make some assumptions,
12-bit (0-4095 BCD) analog output
HMI adjusts output in V-2000 (0-100 BCD no decimal point)
Output V-memory V3000 (set by analog config)
Then your scaling would be:
LD V2000 (0-100 BCD)
MUL K4095 (analog output full scale)
DIV K100 (adjustment full scale)
OUT V3000 (analog output register)
Is this what you 're looking for?

roboteacher, after posting, it dawned on me that you may be looking for suggestions for hardware? I suggest the C-more for your operator interface. Look at the following link for I/Ps.

Hope this helps
