tween master and slave. In line with CANopen, a difference is made between Rx (re-
ceive) and Tx (transmit) process data objects.
Rx process data
objects
Rx process data objects (Rx-PDO) are received by the EtherCAT
®
slave. They transport
process output data (control values, setpoints, digital output signals) from the
EtherCAT
®
master to the EtherCAT
®
slave.
Tx process data
objects
Tx process data objects (TX-PDO) are returned from the EtherCAT
®
slave to the
EtherCAT
®
master. They transfer process input data (actual values, statuses, digital
input information, etc.).
In the DFE24B operating mode of MOVIDRIVE
®
B, two different PDO types can be used
for cyclical process input and output data.
• OutputData1 (standard 10 PO)
Static PDO with 10 cyclic process output data words that are connected in fixed con-
figuration with the standard process data of MOVIDRIVE
®
B (see "MOVIDRIVE
®
B
Communication and Fieldbus Unit Profile" manual).
• OutputData2 (Configurable PO)
Configurable PDO with up to 10 cyclical process input data words (16 Bit) and up to
8 cyclical system variables (32 Bit) that can be configured as required and connected
to various process data of the drive inverter.
• InputData1 (standard 10 PI)
Static PDO with 10 cyclic process output data words that are connected in fixed con-
figuration with the standard process data of MOVIDRIVE
®
B (see "MOVIDRIVE
®
B
Communication and Fieldbus Unit Profile" manual).
• InputData2 (Configurable PI)
Configurable PDO with up to 10 cyclical process input data words (16 Bit) and up to
8 cyclical system variables (32 Bit) that can be configured as required and connected
to various process data of the drive inverter.
