er Specific Objects
•
Object mounted only on Slave Units operating in the DC mode.
•
The number of sequences for detecting communications errors is set with this object.
•
The setting range is from 00 to 0F hex and the number of detections is "the set number of times + 1."
•
Rewriting value is possible at operation in the DC mode, but the operation is performed with the value
set when shifting from the pre-operational state to safe-operational state. Note that at this point, the
rewritten value is read.
Note: With the default setting of 01 hex, an error is detected if communications errors occur twice in a row.
Precaution for Safe Use
When using the cable redundancy in DC Mode, the Communications Error Setting set value for
EtherCAT Slave Units in DC Mode should be set to "1" (default value) or higher. If the
communications cable is disconnected or the power supply of the EtherCAT Slave Units is
turned OFF with the Communications Error Setting set value set to "0", communications may
discontinue.
•
Object mounted only on Slave Units operating in the DC mode.
•
This object is used to set the standby time until the first synchronization interrupt signal (SYNC0) is
input after shifting to the safe-operational state (state where a DC mode is confirmed).
•
If the first interrupt signal (SYNC0) is not input at all within this setting time, a synchronization error
occurs.
•
The setting range is from 0000 hex to 0258 hex (600s) and operation is performed at 120s when
0000 hex is set.
•
Rewriting value is possible at operation in the DC mode, but the operation is performed with the value
set when shifting from the pre-operational state to safe-operational state. Note that at this point, the
rewritten value is read.
