Introduction
In addition to the factory markings, there are also other options for labeling and/or marking
terminals, BaseUnits and I/O modules for the ET 200SP distributed I/O system.
Optional markings
Color identification labels
The color identification labels are module-specific labels for color coding the potentials of the
I/O modules. A color code (e.g. 01) is printed on each color identification label and I/O
module. The color code allows you to read which color identification label is required for the
terminals of the associated BaseUnit directly from the I/O module.
The following versions of color coded labels are available:
● Module-specific color combinations for the process terminals (see the device manuals
I/O modules (http://support.automation.siemens.com/WW/view/en/55679691/133300
)).
The different colors have the following meaning: Gray = input or output signal, red =
potential +, blue = ground.
● For the AUX terminals in the colors yellow-green, blue or red
● For the add-on terminals in the colors blue-red
● For the potential distributor modules (see manual BaseUnits
(http://support.automation.siemens.com/WW/view/en/59753521
)):
– For PotDis-BaseUnit PotDis-BU-P1/x-R: red
For PotDis-BaseUnit PotDis-BU-P2/x-B: blue
– For PotDis-TB-P1-R: red or gray
For PotDis-TB-P2-B: blue or gray
For PotDis-TB-BR-W: depending on application, yellow/green, blue, red or gray
For PotDis-TB-n.c.-G: gray
Reference identification labels
The reference identification labels (in accordance with EN 81346) can be inserted onto each
CPU/interface module, BusAdapter, BaseUnit, I/O module and PotDis-TerminalBlock. This
makes it possible to create a fixed assignment between the reference identification label of
the BaseUnit and the I/O module/PotDis-TerminalBlock.
With the standard plotter setting, the reference identification label is suitable for automatic
labeling with E-CAD systems.
