Up to eight groups can be arranged. Set for each group whether they are to be
operated in freeze mode and/or sync mode. By assigning the slaves (see "Properties
of the DP slave", "Group assignment") to different groups, the data exchange from
the master via a global control command can be synchronised.
A freeze command causes a master, a slave, or a group, to "freeze" the input in the
current status and transfer these data in the next data exchange process.
A sync command causes the slaves to connect the data received by the master
through to the outputs synchronously regarding time with the next sync
command.
In order to switch on/off the freeze and sync option for one group, left-click the
corresponding position in the table to place/remove an 'X' at the requested option
or right-click it to activate/deactivate the option via a context menu. Moreover you
can edit the group names here.
