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 any 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 t
he 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 162)
Step 2: Stopping the reserve CPU (Page 162)
3 Downloading modified CPU parameters to the reserve
Step 3: Downloading a new hardware
configuration to the reserve CPU (Page 163)
4 Switching to CPU with modified configuration Step 4: Switching to CPU with modified
5 Transition to redundant system mode Step 5: Transition to redundant system mode
