The Axis

Description

An axis is defined using an AXIS_REF type object.

From the user's viewpoint, an AXIS_REF object is:

A structured variable with all the data needed by the MFBs to work with an axis (logical status, mapping, messaging status, etc.),
A variable created automatically during the creation of the axis,
A variable to be addressed to MFB blocks.

The AXIS_REF object is represented by a DDT type structure that contains public data, which can therefore be modified by the axis configuration, as well as data that is not visible and that cannot be modified.

The visible data in AXIS_REF is:

Data	Type	Description
