Operation modes
In EL5101 “enhanced operation mode” the following modes are available:
Mode | DC | Main PDO | Comment | Optional PDO 1 | Comment | Optional PDO 2 | Comment | Features CoE | Comment |
|---|---|---|---|---|---|---|---|---|---|
7 | FreeRun | Count/Latch in 32 bit | or 0x1A06 | Frequency (32 bit) | -- |
| 0x8010:nn
| CoE combinations | |
8 | " | compact: Count/Latch in 16 bit | " | " | -- |
| " | " | |
9 | DC/DCi | Count/Latch in 32 bit | " | " | or 0x1A08 | Timestamp 64 bit | " | " | |
10 | " | compact: Count/Latch in 16 bit | " | " | " | " | " | " |
Other settings may result in irregular process data and lead to error messages in the TwinCAT System Manager logger window.
 | Parameterization • Use a CoE reset in order to deactivate any previous settings • In order to activate the new operating mode, reload the EtherCAT slaves ( |
button)DC (Distributed Clocks)
Describes whether the terminal is operated with distributed clocks support:
- FreeRun: the terminal operates frame-triggered. Cyclic operation is started via the SyncManagers of the EtherCAT frame processing.
- DC-Synchron: cyclic operation in the terminal is started by the local distributed clock at exact intervals. The start time is chosen such that it coincides with other output slaves in the EtherCAT system.
- DC-Synchron (input based): as DC-Synchron mode, with the cyclic start time chosen such that it coincides with other input slaves in the EtherCAT system.
