15.5.2 Data

There is a difference between the transfer of cyclical and non-cyclical data.

15.5.2.1 Cyclical data

Cyclical data is data that is sent between the device and the PLC at regular intervals. The cycle is defined via
the PLC configuration.
Cyclical data is grouped into different modules. The consistency of the data can only be ensured within a
module. If multiple modules in the PLC are interconnected (e.g. new trigger data for each trigger), this must
be taken into account.
For example, you must ensure that the trigger in the control and status module is triggered after the new
trigger data in the trigger data module. This can be achieved by setting the HS flag at the correct time.
If the cyclical data changes, the corresponding reactions are triggered. If the handshake is used, this only
happens when the handshake flag changes. When the connection is first established, actions are triggered
for some data even if this data does not change.
