Reconfiguration Procedure

11.9.4.1

Using a Previously Unused Channel

Procedure
1. Change the hardware configuration and download it to the CPU.
2. Save your project.
3. Make the change to the wiring.
4. Change the user program and download it to the CPU.
11.9.4.2

Reconfiguring an already used channel.

Introduction
The procedure depends on whether or not changes to the user program and the associated
hardware are necessary due to the re-configuration. The individual cases are described
below.
Procedure without change
The user program need not be changed as a result of re-configuration. This is the case, for
example, when you change an alarm limit or when you disable the diagnostic interrupt.
● Change the hardware configuration and download it to the CPU.
Procedure for changing the user program
The user program need not be changed as a result of the re-configuration. This is the case,
for example, when you change the measuring range for a channel of an analog input module
and when you compare the associated analog value with a constant in your program. The
constant must be adapted in this case.
1. Set the values of the channel being re-configured to simulation (in the associated driver).
2. Change the hardware configuration and download it to the CPU.
3. Save your project.
4. If necessary, adapt the user program to the changed channel and download it to the
CPU.
Cancel the simulation for the re-configured channel (in the corresponding driver).
