Color Coding for Identifying the Component Type
To get an overview of the different I/O components quickly and easily, they are color-
coded.

Color Coding for Identifying Functionality
To allow you to get an overview of the component classes present in a node quickly and
easily, they are color-coded.
• Housings with up to four round indicators have permanently installed color-coded pull-
out labeling fields.
• I/O modules in the 8-channel housing can be color-coded by attaching marking ele-
ments (Mini-WSB) above the indicators.
• For housings with 16 indicators, they are highlighted in color.
