Configuration in RUN -
Changes to the configuration during operation
Modifications or expansions are also required during operation of a
plant (section), such as implementation of additional sensors or
actuators, reparameterization of I/O modules (e.g. choosing of other
interrupt limits). Possible applications are non-stop requirements, that
is, in continuous processes that cannot be shut down or whose production
cannot be interrupted: process plants or manufacturing plants with high
restart costs.
With SIMATIC S7-400, hardware configuration changes can be carried out
during operation of a plant without any adverse effects. CiR
(Configuration in RUN) enables plant expansions and conversions during
the operational phase. |

Benefits
- CiR enables plant expansions and optimizations. Expansion and
conversion of a plant can be made during operation of the process.
These changes to the plant are reaction-free. This means expansions
and conversions can be carried out faster and at lower cost.
- In addition, modifications in RUN enable an extremely flexible
response to process changes and process optimizations.
- The time needed for the conversion of plants with no nonstop
requirements can also be reduced through changing and reconfiguring
during RUN because the plant does not have to be re-initialized or
synchronized due to hardware configuration changes..
Application
Changes to the hardware configuration in RUN are possible with
distributed I/O. All standard CPUs of the S7-400 can be used, as well as
the S7-400H fault-tolerant CPUs in standalone operation. CiR processes
can be carried out with the following DP masters:
- CPU via integral interfaces
- CP 443-5 ext (from V5.0)
- Interface-Modul IF 964-DP
S7-400H CPUs in redundant configurations can be modified during
operation using the H-CiR function.
Functions
The following hardware configuration changes can be carried out during
plant operation:
- Addition of distributed I/O nodes (PROFIBUS DP and PROFIBUS PA
slaves), e.g. for establishing an additional process line
- Adding of I/O modules in the ET 200M distributed I/O system, e.g.
for implementing additional sensor technology
- Undoing changes, that is, field devices (DP/PA slaves) and modules
that have been added can be removed again
- Reparameterization of I/O modules in the ET 200M I/O system, e.g.
replacing parts when using a sensor with another specification, or for
selecting other interrupt limits
