System stop error codes
A system stop error can occur due to incorrect configuration or defective hardware.
The error code is indicated by the red "Error" LED and four switch-on phases. Each switch-on phase has a duration
of either 150 ms or 600 ms. The error code output is repeated cyclically every 2 seconds.

Description
State
The interface is in state PRE_OPERATIONAL_2.
Managing node (MN)
The MN begins cyclic communication (cyclic input data is not yet evaluated). The CNs are configured in this state.
Controlled node (CN)
The interface can be configured by the MN in this state. A command then switches the state to READY_TO_OP-
ERATE (triple flash). A solid red LED in this mode indicates failure of the MN.
State
The interface is in state READY_TO_OPERATE.
Managing node (MN)
Cyclic and asynchronous communication is taking place. Any received PDO data is ignored.
Controlled node (CN)
The configuration of the module is completed. Normal cyclic and asynchronous communication is taking place.
The transmitted PDO data corresponds to the PDO mapping. Cyclic data is not yet evaluated, however. A solid
red LED in this mode indicates failure of the MN.
State
The interface is in state OPERATIONAL. The PDO mapping is active and cyclic data is evaluated.
State
The interface is in state STOPPED.
Managing node (MN)
This state is not possible for the MN.
Controlled node (CN)
No output data is output, and no input data is provided. It is only possible to enter or leave this mode by a
corresponding command from the MN.
