Process data

Via the "Process Data" tab, the contents of the available process data objects (PDO) can be displayed in the "PDO Content" (C) field. Changes to the process data can be made via the "PDO Assignment" field.

For the EJ5021 EtherCAT plug-in module no changes can be made via the Sync Manager SM2 "Outputs".
Via the Sync Manager SM3 "Inputs" (A) two additional "PDO Assignments" (B) can be added for the frequency:

0x1A01 "ENC Frequency (int32)"
0x1A02 "ENC Frequency (uint32)"

Process data 1: — EJ5021 - Process data (default)

In order to configure the process data, select the desired Sync Manager (only SM3 can be edited here) in the upper left-hand "Sync Manager" (A) field.
The process data assigned to this Sync Manager can then be switched on or off in the "PDO Assignment" (B) field below.
Restarting the EtherCAT system, or reloading the configuration in Config mode (F4), causes the EtherCAT communication to restart, and the process data is transferred from the module.

All selected process data are displayed in the tree structure (D).

The process data are generated from CoE objects 0x6000 (Inputs) and 0x7000 (Outputs) and are described in chapter "Object description and parameterization".
