Configuring Processor Variables

The 9110 processor module contains status, control, and RTC variables used by the application. Status variables get data from the processor module while control variables set data in the processor module. RTC variables are used for the real-time clock of the application.
Configure the processor variables from the property page of the controller. Each type of processor variable is wired in a separate tab, as seen in the following:
eqv_spv
  • Status
    tab, contains status integers and Booleans supplying data about the controller to the application.
  • Control
    tab, contains control integers and Booleans enabling the application to send data to the controller.
  • RTC
    tab, contains status, program, and control variables for the real time clock. RTC status variables supply the date and time to the application. RTC program variables hold the date and time to be written to the real time clock. RTC control variables set and update the clock.
    Task

    4. From the processor variable tab, locate the required variable, and in the
      Wire
      column click eqv_spv.
    5. The Variable Selector displays.
    6. From the Variable Selector, select the required variable and click
      OK
      .
