A system modification during runtime 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.
Step Action CPU mode System status
1 Configuration of your current (real) system configuration STOP Offline configuration2 Defining CiR elements STOP Offline configuration
3 Configuration download STOP Commissioning
4 Conversion of CiR elements to real objects where
required.
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.
