Process data overview
Manual process data assignment is necessary for TwinCAT up to version 2.10.
Sync Manager (SM)
The scope of the process data offered can be changed via the "Process data" tab (see Fig. Process Data SM2, EL2564 as an example).
The PDOs from the range 0x160n (0x1600 to 0x1604) can be assigned to the Output SyncManager 2 (see Fig. Process Data SM2, EL2564 as an example).
The PDOs from the range 0x1A0n (0x1A00 to 0x1A07) can be assigned to the Input SYNC Manager 3, s. Fig. (Process data SM3, EL2564 as an example) .
Not all combinations are technically useful.
Manual PDO Assignment
To configure the process data,
- 1. select the required Sync Manager (SM 2 + 3 can be edited here) in the "Sync Manager" box at the top left (see fig. Process Data SM3, EL2564 as an example).
- 2. The process data assigned to this Sync Manager can then be switched on or off in the “PDO Assignment” box underneath.
- 3. 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 terminal.
