For each group, select whether it is supposed to be operated in the freeze mode and/or sync
mode. By assigning the slaves to different groups (on the DP Parameters tab of the DP
slaves, Groups... button), you can synchronise the data exchange from the master via a
global control command.
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 activate or deactivate the freeze and sync mode for one group, you can either set
a checkmark at the corresponding place in the table or remove it. Besides, you can change
the names of the groups here.
