| Update Time (Sec) |
The update time for this group.
This Update time is only useful for protocols such as Modbus. In
which the items are constantly polled.
The update time is the elapsed
time for all items in that group to be updated at every poll
cycle. At the start of each poll cycle, a read request is issued for all
items in that group. The elapsed time is calculated when the last item is
returned. IOServer then wait for the remaining of the time before starting the
next poll cycle.
The update time is irrelevant for protocols such as
DNP3, Kingfisher, IEC60870-5-103 and Harris HR6000 because the poll time is controlled internal by the device
configured polling schedule or polling is only done by class.
