u_target

Purpose:

Set the User Control Loop Target

Enter:

u_target <mode> <ctrler> <target>

Where:

mode

Specify the desired control loop mode. Specify either of the following modes: 

  • OPEN to set the open loop control target.
  • closed to set the closed loop control target.

ctrler

Specify the name of the controller performing the control.

target

Specify the value of the control loop target or the label of a real variable containing the target.

Example:

u_target Open fuel_in_temp 50
The above sets the open loop target for the fuel_in_temp controller to 50%.

u_target c fuel_in_temp fuel_t_setpoint
The above sets the closed loop target for the fuel_in_temp controller to the value contained in the real variable, fuel_t_setpoint.

u_target closed fuel_in_temp 104
The above sets the closed loop target for the fuel_in_temp controller to 104.

Notes:

The mode argument may be either upper or lower case. Only the first character is significant.

Use the controller name that is specified in the control specs file under the keyword @USER_CTRL_LOOP. If the old ctrl_specs file format is being used, then the controller name is the name found on the line that contains the user control loop number.
