8.5 System modification during operation

1.
Make the appropriate modifications to the configuration offline (remove or add module).
Note
The parameters of a module can only be changed by making two configuration
modifications in RUN:
1. Remove the module.
2. Add the module with new parameters.
2.
Switch one master of the redundant system to passive (all slaves are active at the other
master).
3.
Load the configuration in the master on the passive line and restart the master →
The parameters and configuration data are loaded in the slave.
4.
Switch over to the line with the new configuration →
The previously loaded configuration now becomes effective. Removed modules are taken
out of the data communication and added modules with the new parameters are included
in the data communication.
5.
The changes are checked by the user.
If the changes are OK, the new configuration must also be loaded in the second master.
If the changes are not OK, the previous status can be restored by switching over to the
second master (with the old configuration). In this case, the old configuration must be
loaded on the first master again.
Note
A reconfigured module can be removed and inserted both before and after system
modification during operation (RUN). It is first available for the process when it is really
inserted and the IM 153-2 that contains the configuration for the module is active.
NOTICE
It is the user's responsibility to ensure that the configuration within the master system is
uniform. It is not shown when the two IM 153-2 are running with different configurations.
If the two masters in the redundant system have different configurations, a system
modification during operation is carried out whenever a switchover is performed.
Interrupts and diagnoses that are generated by the IM 153-2 for an I/O module will be
reported by the passive IM 153-2 to the master, even if this module is not available in the
configuration of the passive IM 153-2. The user himself must decide to which extent the
interrupts and diagnoses from the passive IM 153-2 should be ignored during the period of
differing configuration data.
