PLC-5 scale commands?

Am I just missing something, or is there no scaling commands in RSLogix 5? Im using a PLC-5/40 processor. Thanks

Matt

No you are not missing anything.

SCL and SCP was added to the SLC instruction set to make up for the "missing" onboard scaling on the analog input/output cards.
But especially SCP is useful in many other situations than just analog i/o scaling.

You have to adapt a CPT formula yourself.

Thanks for the links. Its no problem to use the CPT function, just thought I might be missing a SCL command or something similar. Thanks again.
