Additional information for the expansion digital and analog
I/O modules can also be accessed from the Instruction
Leaflet for each module which can be found on the Eaton
website: www.eaton.com. The publication number for the
documents for each analog module and for the digital I/O are
shown below. These documents also include specifications
for the I/O for each card.

In order to control expansion outputs from a remote fieldbus
source, the Remote Control Source must be fieldbus or Logic
Engine. And fieldbus must be the active control source.
Inputs and Outputs can always be monitored via fieldbus
even when fieldbus is not the active control source or even
when it is not even the Remote Control Source.
Any digital or analog I/O addressed in the Logic Engine
program, will not be allowed to be controlled via the remote
fieldbus source.
Below are the I/O layouts for each expansion analog module
on Ethernet/IP and PROFIBUS.
