7.1.3 Configuring PDO transmission
PDO channels are able to transmit control and status information in real time as well as actual and set values from an
EtherCAT master to EtherCAT slaves and vice versa.
PDO communication allows for several PDO channels to be operated simultaneously per transmission and sending
direction. The channels for axes A and B each include a PDO with a defined sequence of up to 24 parameters to be
transmitted. These are free to be configured in any way. One channel is reserved for FSoE communication and is
parameterized automatically.
In order to guarantee error-free communication between the controller and drive controller, STOBER offers an application-
dependent pre-assignment of the channels which can be changed at any time.
7.1.3.1 Adapting RxPDO
ü
You have configured the global EtherCAT settings.
1. Highlight the relevant drive controller in the project tree and click on the first projected axis in the project menu >
Wizard area.
2. Select the EtherCAT wizard > Received process data RxPDO.
3. Check the default settings and/or configure the process data according to your requirements.
A225[0] – A225[23], A226[0] – A226[23]:
Parameters whose values are received by the drive controller from the controller. The position of the parameters
provides information about the associated receiving sequence.

ü
You have configured the global EtherCAT settings.
1. Highlight the relevant drive controller in the project tree and click on the first projected axis in the project menu >
Wizard area.
2. Select the EtherCAT wizard > Transmitted process data TxPDO.
3. Check the default settings and/or configure the process data according to your requirements.
A233[0] – A233[23], A234[0] – A234[23]:
Parameters whose values are sent to the controller by the respective drive controller. The position of the parameters
provides information about the associated transmission sequence.
