can i use PF525 as input unit?

Hi,Guys:
since we used all inputs of the PLC, no any input left for our new project.we have a few PF525 connected with Ethernet, can we use it for input unit?
thanks!

Flip through the manual, should be obvious.

We do it all the time with Control Techniques, I'd bet you can look at the input status bit or register on the PF and do the same...

Any reasons you can't use remote IO?

Some pretty good systems that run over ethernet and are rated IP67 (or better) and can be mounted in the field.

Parameter 14 is the Dig In Status, and the first 4 bits monitir terminals 5 to 8.
P14 bit 0 = terminal 5, and so on.
You would need to use a datalink to get the status to your PLC, note the datalink values cannot be changed if you have an established I/O connection to the drive.

It’s done all the time.

We will try it.
Thanks everyone!

You can monitor up to 4 parameters on a 525 drive at the RPI you have set for the drive. This is set in the module configuration where you select the HP, revision, and keying options. You could potentially use this for IO. If the IO is not related to drive function I would highly recommend adding a card or remote IO solution since it would be quite confusing to troubleshoot.
