There are some process cells that must not be shut down during operation. Using CiR (Configuration in RUN) to make changes to a plant during operation it is possible to make certain changes to the configuration in RUN mode.
When adding components or changing their parameters using CiR (Configuration in Run) the station with the highest PROFIBUS address
- Must be an S7-compatible DP slave (DPS7 slave).
- Must not be configured with GSD file.
Otherwise the component added or reparameterized with CiR is not parameterized by the CPU and is therefore not ready for operation although the station supports CiR and the CiR elements are configured.
In the Hardware Configuration you can see whether a DP slave has been configured with GSD file. Double-click the DP slave configured to open the Properties dialog of the DP slave. In the "General" tab the name of the GSD file is displayed if the DP slave has been configured with GSD file.
This applies for the S7-400 Standard CPUs and PROFINET CPUs up to the firmware versions below:
This applies for the fault-tolerant S7-400 CPUs is you have configured S7-400 as standard system and not H system S7-400H up to the firmware versions below:
Assign a DPS7 slave not configured with GSD file the highest PROFIBUS address.
More information about configuring the CiR function (Configuration in Run) is available in the manual "SIMATIC STEP7 V5.5 Modifying the System during Operation via CiR". The manual is available for downloading in Entry ID: 45531308.
