Changing binary and analog variables
Variables are often used for setpoints so that they can be changed by the
building operator or owner from the operator display. In the Rover service
tool, binary and analog variables can be changed from the Displays tab.
To make a change from the Displays tab or from the operator display, the
following must be true:
• The variable must be a local variable with the control source set to
the operator display/service tool. For information on configuring
binary and analog variables, see “Configuring variables” on page 31.
• The variable must be designated as adjustable in the display configu-
ration. For information on setting a variable to be adjustable, see
“Configuring custom displays” on page 41.
Upon changing, the selected variable value changes to the requested
value. The control source of the variable does not change, so other control
sources, such as the operator display, can still affect the value of the vari-
able.
To change a binary or analog variable in the Rover service tool:
1. In the Active Device View, click the Displays tab.
2. In the Display list, click the name of the custom display that contains
the variable you want to change.
3. In the table, click the name of the variable you want to change.
4. Click the Change button. The Change Local Analog Variable dialog
box appears (Figure 15 on page 16).
Note:
Variables cannot be changed from the home display on the oper-
ator display or in the Rover service tool.
Note:
If the Change button is not available, the variable you chose
does not meet the criteria outlined previously.
