CiR objects and CiR modules for PROFINET DP
11.7.1
Basic Requirements
Overview
A system modification during RUN via CiR is based on the provisions you have made in your
initial configuration for an expansion of your PLC hardware. Define suitable CiR-compatible
elements that you can later replace step-by-step in RUN mode with real objects (slaves
and/or modules). You can then download such a modified configuration to the CPU during
runtime.
Procedure
The table below shows the procedures required for modification of the program and of the
configuration, as well as the corresponding system phase.

System modifications are only possible on master systems
which contain a CiR object or on ET 200M stations which
are equipped with a CiR module.
RUN
Continuous operation
If required, execute several passes of the CiR sequence (step 4 of the table above). You
merely have to provide a sufficient number of slaves or adequate I/O volume for all of your
system expansions before you switch to continuous operation.
