11.5.5 Poll Groups
In a Modbus network, the master has to poll the slave devices. Input data points are
therefore attached to a poll group. If nothing else is specified, the default poll group is used
for input data points. The default poll group has a poll cycle of 60 seconds.
Two different types of poll groups can be specified:
Time-based: The poll group is triggered on a time base. This means that after a
specific time – the poll cycle – the poll group is processed.
Trigger-based: The poll group is triggered on a special trigger data point. As soon
as the trigger condition is met, the poll group is processed.
Tip:
The poll group a data point is attached to can be changed in the properties view of the
data points. The poll group can also be changed for multiple data points using multi-
select.
