Changing Configuration
During CFM Module
Operation
After the module has begun operation, you can only change configuration by
using ladder logic and message instructions.
Follow these steps to change module configuration during operation:
1. Access the data structures through the tag monitor to make specific
configuration changes, see page 77 .
2. Use ladder logic and a configuration message instruction to send the
configuration changes to the module, see below through page 85 .
Using Ladder Logic
You must use ladder logic to perform these operations on your module:
• change configuration
• perform run time services
Ladder logic uses message instructions to exchange data between the
controller and module. You can access the ladder logic by double-clicking on
the Main Routine portion of the MainProgram.
