FREEZE
With this function all the inputs of the valve
terminal can be "frozen". The valve terminal then
sends a constant input image of all the inputs to
the master. The following FREEZE command
causes the input image to be updated. The
updated input image is then sent constantly to
the master.
You can return to normal mode with the
command UNFREEZE.
SYNC
With this function all the outputs of the valve
terminal can be "frozen". As a result the valve
terminal no longer reacts to modifications to the
output image in the master. The following SYNC
command causes the output image of the master
to be updated and transferred.
You can return to normal mode with the
command UNSYNC.
