Micrologix 1000 scaling

[KTM Rider 0]

I'm working on a project that uses a micrologix 1000 and a panelview c300. I need to figure out a way to create an "scp" in the micrologix....has anybody tried this? Of course I cannot scale in the c300 and the micrologix does not do floating point math Thanks for any help

For a Voltage Input ( 0-10volts = 0-31207 raw value) Scaled Value=(Raw Value/31207)*Max Scaled Value i.e. 50=(15604/31207)*100 For a Current input (0-4ma=6241 to 31207 raw value) Scaled Value= ((Raw Value-6241)/24966)*max Scaled Value i.e. 50=((18724-6241)/24966)*100 Use math instructions DIV,MUL,Sub Example shown is for a max scaled value of 100 your process may differ.
