Product overview
EL37x2
20
Version: 3.5
Each terminal now transfers a 400 byte process data packet to the higher-level control system. If these two
data sets (which are offset by 5 µs) with a length of 1 ms each are sorted in the right chronological order in
the control system, the wanted signal is transparently sampled at 200 kSps.
The application of these functions using the Beckhoff TwinCAT System Manager is described in section
Process data and configuration [

.
Note
SYNC0 and SYNC1 pulse with several EtherCAT slaves
This approach of matching the SYNC0 and SYNC1 pulses of several EtherCAT slaves is
not limited to EL37x2.
All EtherCAT slaves supporting the distributed clock function can be correlated relatively
freely in this way.
Attention
Attention! Risk of device damage!
The above notes and information should be used advisedly.
The EtherCAT master automatically allocates SYNC0 and SYNC1 settings that support reli-
able and timely process data acquisition.
User intervention at this point may lead to undesired behavior.
If these settings are changed in the System Manager, no plausibility checks are carried out
on the software side.
Correct function of the terminal with all conceivable setting options cannot be guaranteed.
Timestamp of the process data
The EL37xx can provide a "timestamp" for each process data block, if required. This process record can be
activated as
StartTimeNextLatch
, a as 32-bit value, by activating 0x1B10 in the
Process Data
tab, see also
