Index 1C32 SM output parameter
Index (hex) Name Meaning Data type Flags Default
1C32:0B SM event missed
counter
This entry contains the number of missed SM events in
OPERATIONAL (DC mode only). The counter is auto-
matically reset at the transition from SAFEOP to OP. If it
increments, then the SYNC shift time for outputs in the
case of the EtherCAT master is too short.
UINT16 RO 0x0000 (0
dec
)
1C32:0C Cycle exceeded
counter
This entry contains the number of cycle time infringe-
ments during OPERATIONAL (cycle was not completed
in time or the next cycle began too early). The counter is
automatically reset at the transition from SAFEOP to OP.
If it increments, then the cycle time of the EtherCAT mas-
ter is too short.
UINT16 RO 0x0000 (0
dec
)
1C32:0D Shift too short counter This entry contains the number of times the distance be-
tween SM2 and SYNC 0 event (DC SYNC0) or between
SYNC0 and SYNC1 event (DC SYNC1) was too short.
The counter is automatically reset at the transition from
SAFEOP to OP. If it increments, then the SYNC shift
time for outputs in the case of the EtherCAT master (DC
SYNC0) or the SYNC1 shift time in the case of the
EL6731 (DC SYNC1) is too short.
