21.5 Configuration
21.5.1 General information
A CECX-system needs data for the configuration of system performance,
its I/O-devices and interfaces. The system reads this data during the start-
up operation and allocates them to its components and devices.
Configuration data is created by included configuration tools.
21.5.1.1 Setting the address
The modules are addressed via the address switch. A maximum of 12
modules of the same type can be distinguished on one line.
The address switch is located on the right side underneath the lower cover.
The K-Bus plug is located underneath the upper cover.

Information
Modules of the same type that are installed within the same line must have
different address switch positions. Different modules (e.g. CECX-C-2G2
and CECX-A-4E4A-A) may have the same address switch positions.
The lids for the K-Bus plug and the address switch must remain locked at
the last module in the line (to protect it against pollution and damage
through electrostatic discharge on contact).
