Shift Time
The Shift Time can be used to shift the SYNC0 pulse for this EtherCAT Box relative to other Boxes/
Terminals and the global SYNC pulse in nanosecond steps. If the inputs of several Boxes are read
simultaneously, the same value must be entered here.
Based on input reference
If this option is activated an additional Input Shift is added to the configurable terminal-specific SYNC0 shift
(user defined). This value is calculated and made available by the EtherCAT master (SysMan/Device
EtherCAT/Tab EtherCAT/Advanced Settings/Distributed Clocks/Input Shift Time). As a result,
all
the input
terminals in the system (EL1xxx, EL3xxx, EP1xxx, EP3xxx) read their inputs as close as possible to the time
of the EtherCAT frame that will fetch them, thereby supplying the most recent possible input data to the
controller.
Enable SYNC0
Automatically activated in
DC-synchron
operation mode.
SYNC1
Additional SYNC pulse, derived from SYNC0 or from the DC itself.
DC settings for EtherCAT master
Higher-level distributed clock parameters can be modified under advanced settings for the EtherCAT master.

Distributed Clocks and EP1518
Digital inputs and Distributed Clocks
If the Distributed Clock of the EP1518 is activated, the digital inputs are read in without the set filter
promptly before the arrival of the querying EtherCAT datagram.
