After power-up, the module carries out self-testing. During this phase, the LED indicators blink.

The module does not operate with a default configuration. It must be sent this configuration by the Control Expert application with a terminal connected to the terminal port of the PLC containing the module.

The configuration values are given in the list of language objects %KW.

The network, station address is given by the thumbwheels on the front panel.

When the configuration is received, the module resets the current communication to zero before configuring itself (terminates current exchanges, shuts down TCP connections).
