Saving settings as persistent data
To save the current settings of a valve on the Motion Terminal as persistent data, the transfer control
method "save persistent" (transfer control = 4) is used. No special channel is required for this; the
value in the section "channel" is not evaluated.
After performing a teach-in run, the "save persistent" function should be executed. The appropriate
parameters for the data acquired in the teach-in run are thereby permanently saved on the controller
for the Motion Terminal.
Otherwise, the teach-in run must be executed again after restarting the Motion Terminal (
