Function
This bit field contains the position of the I/O module that
reported the diagnostic event.
'0x00' ... '0x3F': I/O module position 0 ... 63.
This bit field contains the number of the signal channel by
means of which the diagnostic event was determined.
'000' ... '111': number of the signal channels 0 ... 7.
This bit field contains the coding of the diagnostic event.
'111': The diagnostic event was reported by an analog I/O
module.
All further bit combinations are assigned to digital I/O modules.
The diagnostic coding is entered in the bit field as it is provided
by the I/O module. The meaning of the coding is available in
the documentation associated with the I/O module.
This bit acknowledges the receipt of the CLEAR command

from the EtherCAT
the CLEAR command active for as long as it takes until the
fieldbus coupler acknowledges the receipt of the command via
this bit. Then the EtherCAT
command in the diagnostic control word.
0: The fieldbus coupler has not received a CLEAR command
or has not yet processed a CLEAR command.
1: The fieldbus coupler has received and processed a CLEAR
command. All entries in the diagnostic buffer have been
purged.
This bit indicates that at least one event is stored in the
diagnostic buffer.
0: No event is present in the diagnostic buffer. The status of
bits D13:D0 of the diagnostic status word may not be
observed by the EtherCAT
1: At least one event is stored in the diagnostic buffer. The bits
D13:D0 of the diagnostic status word contain the
description of the diagnostic event.
Additional events, which are stored in the diagnostic
buffer as necessary, are only displayed after this event
has been acknowledged by the EtherCAT
