Control by the higher-level PLC is carried out via ready-made function blocks.
This ensures that the programmer has only minimal concern with the details of the axis.
These function blocks are completely implemented in the CPM-1000 with
the integrated control and their input and output data are transported
via the network.
This is beneficial in several ways.
-
Due to the speed of the CPM-1000, the function blocks are executed
at high speed and possible delays in the higher-level PLC are reduced.
-
The PLC and the network are relieved of time-critical tasks.
-
This transparent interface results in high reliability of the system
as no executable code is installed in the PLC.
-
Specific properties on the part of the PLC have no influence on the
function of the function block.

Extensible function blocks
To be prepared for situations where standard functions are not sufficient,
the range of functions of the CPM-1000 can be extended at any time, without
the need for special firmware adjustments.
To make this possible, the ready-made function blocks are completely
implemented on the user level with the integrated control and are provided
as source code.
This enables the programmer to modify existing function blocks, to add or
to create new function blocks.
In this way, the simplicity of standard functions is combined with the
flexibility of free programmability.
As a result of this it is achieved that the system manufacturer can
react very quickly to new requirements and at the same time his own
process know-how is completely in his hands.
