Chapter 3 Configure a ControlNet Module
If you use Disabled Keying, you must take full responsibility for understanding
whether the module being used can fulfill the functional requirements of the
application.
EXAMPLE In the following scenario, Disable Keying prevents I/O
communication :
The module configuration is for a 1756-IA16 digital input module. The
physical module is a 1756-IF16 analog input module. In this case,
communication is prevented because the analog module
rejects the data formats that the digital module configuration
requests .
