Send global control commands to a single or all slaves to synchronize process data.

Via using global control commands input or output data of slaves can be synchronized. The commands are selected by different combinations at inputs Freeze / Unfreeze and Sync / Unsync. The slave devices are selected by using individual slave addresses or broadcast address 127 and using PROFIBUS grouping functionality via input GroupSelect.
