System variables

The system variables include the input and output variables as well as the internal variables.
The input and output variables can be used to exchange values of different data types between the de-
vice and the ST module integrated in the device. The internal variables are only relevant within the ST
module and can be used to implement certain functions.

Input variables

The input variables provide device values for use in the ST module.The input variables provide device
values for use in the ST module.
The values are assigned to the input variables in the setup program by selecting the respective signals
from the selectors (analog selector or digital selector).
Variables with fixed assignment in the device are not available in the selectors.

Description
Boolean input variables; flexible assignment in the
setup program (digital selector)
Description
Real input variables; flexible assignment in the set-
up program (analog selector)
Description
These double-word input variables are not avail-
able on the device side. They can be used as a
buffer in the ST code.
