Communications Operation Command to Move to the Protect function group
The Write Variable operation command can be used via communications to
write the password to the Move to Protect function group parameter. When
the correct password is written, the display will change to the Operation/
Adjustment Protect parameter and writing the parameters in the Protect
function group will be enabled.
Note: If the Write Variable operation command is used to write the wrong
password to the Move to Protect function group parameter after the
correct parameter has been written, the Move to Protect function group
parameter will be displayed and any Write Variable operation
commands to write parameters in the protect function group will result
in operation errors.
Note: If a password is not configured or if it is configured to 0, the display will
change to the Operation/Adjustment Protect parameter and writing the
parameters in the Protect function group will be enabled immediately.
