About Variables

Variables are measurements or calculations attached to a given production unit that produce values either by time or event. Variables are created in Plant Applications Administrator. Using the Autolog (Preview) application, you can:
  • Enter the values for these variables.
  • Identify whether the values are within acceptable limits.
  • Depending on the configuration in Plant Applications Administrator, receive alarm notifications and acknowledge them.
The following conditions apply when you enter or modify a variable value:
  • You must configure a variable and include that variable on an autolog display using Plant Applications Administrator.
  • If the data source of the variable is Autolog, you must have the Read/Write, Manager, or the Admin privilege.
