System modification during operation in stand-alone operation
With a system modification during operation, it is also possible to make certain configuration
changes in RUN in stand-alone operation of a CPU 410-5H. Processing is halted during this,
but for no more than 2.5 seconds (can be assigned). During this time, the process outputs
retain their current values. In process control systems in particular, this has virtually no effect
on the process. See also Manual
"Modifying the System during Operation via CiR".
System modifications during operation are only supported with distributed I/O. They require a
configuration as shown in the figure below. To give you a clear overview, this shows only
one DP master system and one PA master system.

Hardware requirements for system modifications during operation
To modify a system during operation, the following hardware requirements must be met at
the commissioning stage:
●
CPU 410-5H in stand-alone operation
●
If you use a CP 443-5 Extended, this must have a firmware V5.0 or higher.
●
To add modules to an ET 200M: Make sure that the IM 153–2 or IM 153–2FO you are
using is included in the list of modules approved for PCS 7.
●
If you want to add entire stations: Make sure that you have the required connectors,
repeaters, etc.
●
If you want to add PA slaves (field devices): Make sure that the IM 157 you are using is
included in the list of modules approved for PCS 7 and use it in the associated DP/PA
Link.
