Which components can be modified?
The following modifications can be made to the hardware configuration during operation:
● Adding or removing modules in the central controllers or expansion units (e.g., one-sided
I/O module).
Note
IM 460, IM 461 and CP 443-5 Extended
Adding or removing IM460 and IM461 interface modules, external CP443
-5 Extended D
P
master interface modules and their cables is only permitted in a de
-energized state.
Note
Signal modules capable of generating substitute values in the central controller
The minimum I/O retention time is ineffective in case of a system change for s
ignal
modules capable of generating substitute values in a central controller. There is always a
gap of 3 to 50 ms.
● Adding or removing components of the distributed I/O such as
– DP slaves with a redundant interface module (e.g., ET 200M, ET200iSP, DP/PA link,
or Y Link)
– One-sided DP slaves (in any DP master system)
– Modules in modular DP slaves (ET200M and ET200iSP)
– DP/PA couplers
– PA devices
● Changing specific CPU parameters
● Reassigning the module parameters
● Assigning a module to another process image partition
● Upgrading the CPU version
● Upgrading to a higher product version or a current version of used components, such as
DP-IMs or external DP interface modules.
Note
No changes to the PROFINET IO interface during operation
I/O components that are connecte
d to a PROFINET IO interface as well as parameters of
the PROFINET IO interface cannot be modified during operation.
Follow the rules for assembling a fault-tolerant station when making any modifications (see
section Rules for the assembly of fault-tolerant stations (Page 29)).
