842e Encoder...

[JohnnyQuanex]

What's the best instruction in Studio 5000 for working with the encoder..?

That is like "what is the best color for painting?" or "What is the best tool to use on a car?"

What do you want to do with the encoder based information? (I noted that in your previous posts you seem to have connected it ok.)

I want to count rotations and scale that for inches of strip length...

The ordinary 842E encoders are an EtherNet/IP networked absolute encoder and work as an I/O device.

The 842E-CM versions actually work as Logix Integrated Motion devices and use the motion control instruction set.

With the ordinary one, you have the Position value right there in the Input tags associated with the encoder.

This seems like a very straightforward linear scaling application. The onboard "Enable Scaling" feature might even allow you to do the conversion to inches right in the encoder, without any ladder logic.
