Table 1: PDO assignment of the SyncManager

Distributed Clocks

The EL41x4 can be operated with and without the Distributed Clocks functionality; see figure for conversion.

Sync Manager (SM) 1:
Conversion of EL41x4 to DC mode

In DC mode the EL41x4 outputs its output values synchronously with other output units, taking into account the DC settings (DC tab --> advanced settings) and the electrical conversion time.

Note regarding FW01: operation with an EtherCAT cycle time of < 400 µs is not possible in DC mode; the EL41x4 remains in SAFEOP.
