Hello, I agree it's better to use the V-memory for input/ output with HMI, big advantage is that you can set default value in the data block for your setpoints (and change them with HMI) and off course you are not mixing with any hardware outputs. For the scaling have a look at How can you scale analog values with S7-200 in conjunction with CPU224XP and expansion modules EM 231, EM 232 and EM 235? Verry easy to use blocks to scale/unscale your analog values. Regards, Marcjan |
