CAN Bus Encoder on CompactLogix

niteman9 · Apr 23, 2013

Does anyone know of a way to use CAN Bus encoders on a Compact Logix system.

'CAN Bus' is a general term; are you using DeviceNet, or CANOpen, or some other CAN protocol ?

CompactLogix has no built-in CAN port, so you'll need a 'scanner card' for whatever protocol you are using.

I recently saw a presentation on some EtherNet/IP encoders that can be used with ControlLogix or CompactLogix motion control as auxiliary axes. Pretty neat !

Thanks for the reply. The issue is I am upgrading a machine which currently has 4 MTS CAN Bus encoders which are wired to a Moog rack. We are replacing the Moog valve with Rexroth and need the ecoder values in the compactlogix processor. I found an Anybus converter that may work but not sure.

You can use SSI output mts rods.

Then buy 2 of this SSI interface module.

I guess I wan't totally clear. The machine has Can Bus encoders on it currently.
I do not want to replace the encoders. If I did replace them I would use DeviceNet encoders.

The Anybus Communicator for CAN, can be used with any CAN based protocol (DeviceNet excluded). However, you will need to know how the CAN-based protocol works, in order to be able to configure it.
Below is the link to the Anybus Communicator for CAN for DeviceNet:
