Data sheet V 1.00
Single flash (approx. 1 Hz)
PRE_OPERATIONAL_1
The interface status is PRE_OPERATIONAL_1.
Managing Node (MN)
The MN starts the operation of the "reduced cycle". Collisions are allowed on the bus. There is not yet any
cyclic communication.
Controlled Node (CN)
The CN waits until it receives an SoC frame and then switches to PRE_OPERATIONAL_2 status (double
flash).
Double flash (approx. 1 Hz)
PRE_OPERATIONAL_2
The interface status is PRE_OPERATIONAL_2.
Managing Node (MN)
The MN begins with the cyclic communication (cyclic input data are not yet evaluated). The CNs are configured
in this status.
Controlled Node (CN)
In this status the interface is normally configured by the manager. After this, a command changes the status
to READY_TO_OPERATE (triple flash).
Triple flash (approx. 1 Hz)
READY_TO_OPERATE
The interface status is READY_TO_OPERATE.
Managing Node (MN)
Normal cyclic and asynchronous communication. Received PDO data are ignored.
Controlled Node (CN)
The configuration of the interfaces is complete. Normal cyclic and asynchronous communication. The PDO
data sent corresponds to the PDO mapping used. However, cyclic data is not yet evaluated.
On
OPERATIONAL
The interface status is OPERATIONAL.
Blinking (approx. 2.5 Hz)
STOPPED
The interface status is STOPPED.
Managing Node (MN)
This status is not possible for the MN.
Controlled Node (CN)
No output data are produced and no input data are received. Only the appropriate command from the manager
can enter or leave this state.
