User If the Unsync bit is set, the Unsync command will be send to the tar-
geted slave devices.
The Unsync command releases the targeted slave devices from the
Sync mode (see below).
User The bit set to OFF indicates that the Unsync command will not be trans-
ferred to the slave devices.
User The Sync command forces the slave devices into the Sync mode. In
this mode the slave device will not update its outputs and continues to
use the output data received before the Sync command.
If the slave device is already in the Sync mode, a new Sync command
will force the slave to update its outputs only once, with the most recent
output data received from the Master.
User The bit set to OFF indicates that the Sync command will not be trans-
ferred to the slave devices.
--- These bits are reserved by the system and will ignored by the Unit.
The user can set the Freeze and Unfreeze bits at the same time, and both will
be transmitted to the targeted slave devices at the same time but the resulting
action at the slave device is defined in the PROFIBUS standards.
