Slc 500 Pid Block

[pauly]

Does any one know how to change the output of a PID block within RS logix to a time proportioned output for temperature control?

did you take a look at the "official" way of doing it in:

the SLC Instruction Set Reference Manual

this subject is covered on pages 9-30 and 9-31 ...

this should get you started ...

hi

Search the ab knowledge base, there are several documents describing
unipolar, bipolar etc time proportioned outputs. I used these with success last year on a drier. If you can't find them post again and i will dig out the doc numbers

Here is an example for you! I done this with an example from the Document reference guide last night and got it working! this example uses less programming so may be easier.
