 Freeze Mode
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.

 Sync Mode

Description
TRUE:
The Freeze command forces the slave devices
into the Freeze mode. In this mode a slave
device will not update its inputs to the Master
and continue to transmit the input data acquired
before the Freeze command.
If the slave device is already in the Freeze
mode, a new Freeze command will force the
slave to update its inputs only once and con-
tinue to transmit the new input data to the Mas-
ter.
FALSE:
The Freeze command will not be transferred to
the slave devices.
TRUE:
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).
FALSE:
The Unsync command will not be transferred to
the slave devices.
TRUE:
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.
FALSE:
The Sync command will not be transferred to
the slave devices.
