In modular machine concepts, you can distribute the functionality between multiple machine
modules, each with its own controller. You can distribute the master value source and
synchronous axes between the various controllers. Coupling between the master axis/an
external encoder and the following axis is isochronous via PROFINET IO with IRT. Control
cycles for the axes are synchronized.

Scaling with technology I/Os and technology modules
The integrated eight digital input/outputs (interface X142) provide configurable technology
I/Os.
Of the integrated eight digital input/outputs of the SINAMICS Integrated (interface
X122/132), you can also use eight digital inputs as measuring inputs.
To expand the integrated technology I/Os high-performance technology modules in the
ET 200MP and ET 200SP distributed I/O systems, for example for additional measuring inputs
and output cam outputs.
Information on technology objects for measurement sensing inputs and output cam outputs
can be found in the section Technology functions of the CPU (Page 85).
