8 System variables and status information
8.1 General information
This section describes the system variables that are available for the controller.
The controller has a register set that is used for diagnostics and easy control of the controller
and the Axioline F local bus.
The diagnostic data is stored in the diagnostic status register and the diagnostic parameter
register. These registers are available to the application program as system variables (sys-
tem flags, global variables).
8.2 Diagnostic status register
Information on the operating state of the Axioline F local bus is stored in the diagnostic sta-
tus register. A specific Axioline F local bus state is assigned to each bit in the diagnostic sta-
tus register.
The following system variables can be used to read the diagnostic status register informa-
tion.
