Description
Variable Name
The variable name, for example, @GV.FLOW_RATE.
Variable Value
The value, which could be an analog value, a string
value, or a logical state (True/False) or (On/Off). Analog
values are displayed in floating point format, for
example, 0.0125, 99.627, and 1287.66. When the
display cannot show the value in floating point format,
scientific format is used (1.287668E+10 or 1.25E-02).
Variable Inhibit
Status
CE (Control Enable) means logic in the ControlWave
project (application) can update this variable.
CI (Control Inhibit) means logic in the ControlWave
project (application) cannot update this variable.
ME (Manual Enable) means an operator can update this
variable.
MI (Manual Inhibit) means an operator cannot update
this variable.
Note: The application programmer is responsible
for implementing variable inhibit/enable logic
through appropriate function blocks for this to
operate.
