Plant changes in RUN - CiR
11
11.1
Motivation for CiR via PROFINET IO
There are systems that may not be shut down during operation. This may be the case, for
example, due to the complexity of the automated process or the high costs associated with
restarting the system. However, a removal or rebuild may still be required.
Using CiR to make plant changes in RUN, certain configuration changes can be performed
in RUN. This interrupts processing for a maximum of 60 ms.
Note
The term "CiR" stands for "Configuration in RUN". The process for plant changes in RUN
described in this documentation is used. The requirements listed below must be met in this
case.
Hardware requirements for PROFINET IO
The following hardware and firmware requirements must be met for plant changes in RUN
using CiR:
●
Use of a CPU 410 in stand-alone operation, firmware version V8.2 or higher
●
IO devices to which individual I/O modules are to be added or from which individual I/O
modules are to be removed must have CiR capability.
●
Complete IO devices can be added or removed even if they do not have CiR capability.
●
If you want to add I/O modules to an ET 200SP HA:
Use of the IM 155-6 HA requires free slots for I/O modules in the IO device.
Configure ET 200SP HA with slot covers for standby modules. You replace the slot
covers when you install I/O modules later.
Note
CiR-capable devices are marked in color in HW Config.
The following also applies to the IO controller:
●
Your IO controller has CiR capability.
●
If you are using different IO devices, the IO device on which you want to make
configuration changes must support plant changes during operation.
