Electronic Keying
The electronic keying feature automatically compares the expected module, as
shown in the RSLogix 5000 I/O Configuration tree, to the physical module
before I/O communication begins. You can use electronic keying to help prevent
communication to a module that does not match the type and revision expected.
For each module in the I/O Configuration tree, the user-selected keying option
determines if, and how, an electronic keying check is performed. Typically, three
keying option are available:
•
•
Exact Match
•
Compatible Keying
Disable Keying
You must carefully consider the benefits and implications of each keying option
when selecting between them. For some specific module types, fewer options are
available.
