Green - Status
Description
Triple flash (approx. 1 Hz)
Mode
The module is in the READY_TO_OPERATE state.
Managing node (MN)
Cyclic and asynchronous communication. The received PDO data is ignored.
Controlled node (CN)
The module configuration is complete. Normal cyclic and asynchronous communication. The PDO data sent corresponds
to the PDO mapping. Cyclic data is not yet evaluated, however.
An LED lit red in this mode indicates a failure of the MN.
On
Mode
The module is in PRE_OPERATIONAL_2 mode. PDO mapping is active and cyclic data is being evaluated.
Blinking (approx. 2.5 Hz)
Mode
The module is in STOPPED mode.
Managing node (MN)
This status is not possible for the MN.
Controlled node (CN)
No output data is produced or input data supplied. It is only possible to enter or leave this mode after the MN has given
the appropriate command.

Incorrect configuration or defective hardware can cause a system failure error.
The error code is indicated by the red error LED using four switch-on phases. The switch-on phases have a duration
of either 150 ms or 600 ms. Error code output is repeated cyclically after 2 seconds.
