Set a state active or inactive and set the priority for that state if it is ON. This utility creates a utl.TCN.timestamp file in /data/utl/ready/TCN containing the specified state change.


msu_set <key> <on/off> [priority]



Specify a key for the short state descriptions (see example keys below).


Specify “on” to turn the state on or “off” to turn the state off. The default is “on”. If the priority field is to be other than zero, then this on/off field must be entered as well.


Optional. Specify a number from 0 to 3. The default is 0. Use this only when the state is being turned “on”.


msu_set Proto off
The above command sets the “Engine Prototype Parts” state to OFF.

msu_set Mech_Cell on 3
The above command sets the “Mechanic working on cell” state to ON and the priority to 3.

msu_set Spt
The above command sets the “Waiting on Support Engr” state to ON and the priority to 0 (on is the default state and 0 is the default priority).


Note that more than one state may be active at any time. This utility is used to set a state active or inactive and to set the priority for that state if it is ON

The exact spelling of the “key” must be used.

Current keys vary from one site to another.  A list of valid keys can be found within the /data/state_codes file on a test cell.  Example valid keys are shown below (for CTC). The keys are the right-most column.
