A fill-in label is shipped with each I/O base. This label should be attached to the face of the communication adapter or M1 processor adapter that you mount on that base.
This section describes the label and provides an illustrated example.
A completed label provides information about the assembled module and its I/O field devices that can be used by service and maintenance personnel.
The model number of the I/O base is pre-screened onto the fill-in label directly above the color code. The cutout area above the I/O model number allows the pre-screened model number of the adapter to show through.
NOTE: An option adapter may also be used in the assembled module. You will find its model number printed in the upper left corner of option adapter housing.
