Principles of programming a step by step axis

Introduction

Each channel (axis) of the axes control module is programmed using:

the SMOVE function for movements in automatic mode,
the bit objects (%I and %Q) and words (%IW, %QW and %MW), (See Application-specific step by step axes control language objects associated with the module to define:
- the selection of operating modes,
- the control of movements, except for automatic mode,
- the monitoring of the operating status of the axis and the module.

Bit objects and words

The bit objects and words can be retrieved using their address or their symbol. The symbols are defined in the variables editor which offers as a default a symbol name for each of the objects.
