Re-parameterization of a module
10.6.1
Re-parameterization of a module
Refer to the information text in the "Hardware Catalog" window to determine which modules
(signal modules and function modules) can be reconfigured during ongoing operation. The
specific reactions of individual modules are described in the respective technical
documentation.
Note
If you edit any protected parameters, the system will reject a
ny attempt to changeover to the
CPU containing those modified parameters. The event W#16#5966 is written to the
diagnostic buffer. and you will then have to restore the wrongly changed parameters in the
parameter configuration to their last valid values.
The selected new values must match the current and the planned user program.
The fault-tolerant system is operating in redundant system mode.
To edit the parameters of modules in a fault-tolerant system, perform the steps outlined
below. Details of each step are described in a subsection.
Editing parameters offline
Step 1: Editing parameters offline (Page 181)
Step 2: Stopping the reserve CPU (Page 181)
3 Downloading modified CPU parameters to the reserve
Step 3: Downloading a new hardware configura-
tion to the reserve CPU (Page 182)
4 Switching to CPU with modified configuration Step 4: Switching to CPU with modified configura-
5 Transition to redundant system mode Step 5: Transition to redundant system mode
Note
After changing the hardware configuration, download takes place practically automatically.
This means that you no longer need to
perform the steps described in sections Step 2:
(Page 181) to Step 5: Transition to redundant system mode
184). The system behavior remains as described.
You will find more information in the HW Config online help "Download to module
->
uration in RUN mode".
