Maximum PLC
Update Rate
40
Defines the maximum rate (the minimum time interval) for
sending the data sets to the PLC. Settings occur dependent on
the PLC processing speed.
Minimum = 10 ms, maximum = 65535 ms. The default value of
40 ms is suitable for most PLCs.
Note
: If this value is greater than the Heartbeat Update Interval,
the Heartbeat Update Interval is increased (slowed down) to
this value.
Enable Heartbeat
Message
Deactivated
Activates updating of the active data sets with the set
Heartbeat Update Rate.
Note
: Either this option or Update Immediately on Status/Confi-
guration Change must be activated, otherwise no data will be
transferred!
Heartbeat Update
Interval
5000
Specifies the Heartbeat Update Interval in milliseconds with
which the data are updated in the PLC.
Standard = 5000 ms, Minimum = 10 ms, Maximum
= 65535 ms.
Note
: If the Maximum PLC Update Rate is larger than the
Heartbeat Update Rate, the Heartbeat Update Rate is in-
creased (slowed down) to this value.
Update
Immediately on
Status/Configu-
ration Change
Deactivated
Specifies whether the UE410-EN is to update the data in the
PLC immediately when changes occur in the data sets. If not
activated, the update is carried out with the next Heartbeat
Interval.
Note
