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).
Procedure for changing the user program and the hardware
The user program and the hardware must be changed as a result of the re-configuration.
This is the case, for example, when you re-configure an input channel from "0 to 20 mA" to
"0 to 10 V".
1. Set the values of the channel being re-configured to simulation (in the associated driver).
2. Change the associated hardware.
3. Change the hardware configuration and download it to the CPU.
4. Save your project.
5. 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).
Procedure for changing the address area of a HART I/O module
This is the case, for example, when you use IEEE values of a HART I/O module.
Follow these steps:
1. Set the values of the module being re-configured to simulation (in the associated driver).
2. Delete the module in the hardware configuration and download it to the CPU.
3. Insert the module once again and configure it for your configuration as needed.
4. Download the hardware configuration to the CPU.
5. Save your project.
6. If necessary, adapt the user program to the changed module and download it to the CPU.
7. Cancel the simulation for the re-configured module (at the associated driver).
