Beckhoff EPP3504-0023 Short Manual page 221

If the function is to be deactivated because, for example, many messages come in or the EventLogger is not
used, the StartUp entry can be deleted or set to 0. The value can then be set back to 1 later from the PLC
via CoE access if required.

Interpretation
Time stamp
The time stamp is obtained from the local clock of the terminal at the time of the event. The time is usually
the distributed clock time (DC) from register x910.
Please note: When EtherCAT is started, the DC time in the reference clock is set to the same time as the
local IPC/TwinCAT time. From this moment the DC time may differ from the IPC time, since the IPC time is
not adjusted. Significant time differences may develop after several weeks of operation without a EtherCAT
restart. As a remedy, external synchronization of the DC time can be used, or a manual correction
calculation can be applied, as required: The current DC time can be determined via the EtherCAT master or
from register x901 of the DC slave.
Structure of the Text ID
The structure of the MessageID is not subject to any standardization and can be supplier-specifically
defined. In the case of Beckhoff EtherCAT devices (EL, EP) it usually reads according to xyzz:
x
0: Systeminfo
2: reserved
1: Info
4: Warning
8: Error
Example: Message 0x4413 --> Drive Warning Number 0x13
