Clock tab update#

Some EtherCAT devices have oversampling features. Distributed Clock is not supported by the device.The Sync 0 or Sync 1 parameter is not present.Some or none of the content will be available under the following scenarios: Sync 1 Cycle: Unit is synchronized relative to the First Sync Unit.User defined: Unit has its own interval.Sync Unit Cycle: Unit is synchronized relative to the Master Cycle Time.This is changed and automatically updated by changing the Cycle Time value on the EtherCAT Master Settings tab tab. As DC-Synchron mode, with the cyclic start time so it coincides with other input slaves in the EtherCAT system.īase interval in microseconds and is used by the master.Devices are synchronized by the reference clock.Device cyclic operation is triggered by the local distributed clock.DC-Synchron, DC for synchronization, DC-Synchronous.Devices are not synchronized by the reference clock.

The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs master’s SyncManager via the cyclic frame. Device cyclic operation is triggered by the EtherCAT ***EtherCAT is an open, high-performance Ethernet-based fieldbus system.In 'FreeRun' mode the local cycle operates independent of the communication cycle and/or the master cycle., DC unused, SM-Synchronous The cycle time can be modified by the master (optional) in order to change the timer interrupt.

FreeRun In 'FreeRun' mode the local cycle is triggered through a local timer interrupt of the application controller.

Select the Distributed Clock (DC) operation mode. This tab is used to change settings related to the Distributed Clock for all Kollmorgen and third-party devices (both discovered and manually added).
