6 The SM_PLCopen.lib library
The program organisation units provided in the "SM_PLCopen.lib" library are based on the
PLCopen specification "Function blocks for motion control, Version 1.0".
This description is also based on that specification. Program organisation units based on
the PLCopen standard are called MC_<POU name>, whilst 3S-specific program
organisation units are named SMC_<POU name>.
The function blocks that are fully programmed in IEC 1131-3 can be divided into three
categories:
 Program organisation units for the general operation, monitoring and
parameterisation of individual drives
 Program organisation units for the independent motion control of individual drives
– These program organisation units help to move single axes autonomously in
different ways.
 Program organisation units for the motion control of a drive (slave) in accordance with
another drive (master). These program organisation units enable cams, electronic gears
and phase shifts to be realised.
The library also contains visualisation templates for all key program organisation units.
These templates are linked to an instance of the corresponding program organisation unit
and represent its inputs and outputs. They are particularly useful when it comes to creating
and testing applications.
Preconditions
This library is based on the "SM_DriveBasic.lib" library, which contains, inter alia, the
definition of the AXIS_REF structure.
