1. Variable Name (Example 1: @GV.FLOW_RATE) (Example 2: @GV.TOTAL_FLOW_RATE)
2. Value - analog value, string value, or logical value. Values which cannot fit in this field will be
shown as asterisks.
Analog values are displayed in floating point format, for example, 0.0125, 99.627, and 1287.66.
When the value cannot be shown in floating point format, scientific format is used
(1.287668E+10 or 1.25E-02 for example).
3. Questionable Data Status - for analog variables, column 1 will be clear if the status is valid. It
will display a question mark if the status is questionable.
4. Variable Inhibit Status
CE (Control Enable) means this variable can be updated by the ControlWave project.
CI (Control Inhibit) means the variable cannot be updated by the ControlWave project.
ME (Manual Enable) means the variable can be changed manually.
MI (Manual Inhibit) means the variable cannot be changed manually.
5. Alarm Enable (for alarm variables only)
AE - variable is alarm enabled (changes will be reported).
AI - variable is alarm inhibited (changes will not be reported).
6. Alarm State
For Analog Variables:
HH
- high-high alarm
HI
- high alarm
LO
- low alarm
LL
- low-low alarm
! - alarm is unacknowledged

Multiple Signal Display
In Read Mode, pressing MULT (F3) will display the variable name extension, value, and units
for three variables at one time. These variables include the variable displayed when NEXT (F2)
was pressed and the next two variables in the list. Press SNGL [F3] to return to viewing one
variable at a time (see Figure 12A).

Notes for Figure 12
For Logical Variables:
TA
- true alarm
FA
- false alarm
CA
- change-of-state alarm
