Deleting "Manufacturer" results in a start error at the transition into the "RUN" operating state. The target system
then returns into the safe "STOP" operating state.

14.3.5 Rewire addresses
Function
Addresses in the PLC user program can be centrally changed - e.g. IW0 to IW8 - using the "rewire" function. This
means that user programs can be quickly adapted to the modified I/O expansion stage.
Example:
The customer writes a PLC user program for a series of machines. Due to the different machine expansion stage,
the I/O expansion stage of several machines differs, which is the reason that addresses must be individually
changed in the user program. Under certain circumstances, this can involve several hundred addresses. Using
the "rewire" dialog box, for these machines, it is now possible to enter a list of the addresses to be changed, e.g.
inputs and outputs. This is executed using the "rewire" function, and the addresses are changed in the user
program.
