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

System stop error codes
Incorrect configuration or defective hardware can cause a system stop error.
The error code is indicated by the red Error LED using four switch-on phases. Each switch-on phase has a duration
of either 150 ms or 600 ms. The error code is repeated every 2 seconds.

3.4.4.4 Updating firmware
The firmware is a component of Automation Studio. The module is updated to this version automatically.
To update the firmware included in Automation Studio, the hardware must be upgraded (see "Project manage-
ment" / "Automation Studio upgrade" in the Automation Studio help system).
