Monitoring the Values of Variables

While the
AADvance-Trusted SIS Workstation software
 is in online or simulation mode, monitor the values of variables by using these views:
  • Local Variable dictionary
  • Global Variable dictionary
  • IEC 61131-3 language editors
  • I/O wiring
  • ISaVIEW
  • Spy list
Generating monitoring information increases the size of the TIC code created.
For dictionary instances and spy lists, the logical values, physical values, and lock status of variables are displayed in their respective columns. For graphical program organization units (POUs), values are displayed differently depending on their type:
  • Values of variables having the Boolean type are displayed using color. The output value color continues to the next input. The default colors are red when True and blue when False.
  • Values of variables having the DINT, REAL, MESSAGE, and TIME types are displayed as a numeric or textual value.
Depending on the view, the logical and physical values display these messages when variables are unavailable:

  • Offline
    , indication that the local variable is not used in a program or it is a function block instance input.
  • WAIT
    , indication that the variable is either:
    • in online mode and attempting to connect to the target, or
    • in simulation mode and attempting to connect to the simulator.

  • No message, indication that the local variable is not used in a program or it is a function block instance input.
  • WAIT
    , indication that the variable is either:
    • in online mode and attempting to connect to the target, or
    • in simulation mode and attempting to connect to the simulator.
IEC 61131-3 language editors
WAIT
, indication that the variable is either:
  • in online mode and attempting to connect to the target, or
  • in simulation mode and attempting to connect to the simulator.
When variables are unavailable, no message displays and the value is not editable in the
Write Logical Value
 dialog box.
TIP: Increase the refresh rate of logical values, physical values, and locked status in the active view by closing other views that display this data, such as
ISaVIEW
screens and dictionaries.
To generate monitoring information
  1. In the
    Application View
    , select the device for which to generate monitoring information.
  2. In the
    Properties
    window, set the
    Generate debug information
     property to
    True
    .
