Distributed Clocks not activated
• the EL3773 operates according to an internal clock, which is synchronized to the EtherCAT cycle time.
The trigger point in this case is the access to the input Sync Manager SM3.
• As a result the EL3773 can compensate fluctuations in the cycle time to a large extent
• The EL3773 can thus be used in systems that have no Distributed Clocks functionality. The time
accuracy of the measured values is reduced, however.
The EtherCAT cycle time must be selected such that
• it is not less than 100 µs
• the oversampling interval does not produce a non-periodic time value – for example, 33.3 µs is not
allowed for the oversampling cycle
The Distributed Clock is to be deactivated in the
DC
tab

The permissible oversampling rates are then set via the System Manager:
