I/O Modules
35013379 02 October 2007 501
To implement the user-optional secondary keying code (designed to prevent the
mismatching of terminal strips to I/O modules of identical type), 17 slot positions
have been provided in modules and terminal strips to support a variety of coding
schemes.
In addition (by using the secondary keying code), the user may key the field wiring
terminal to the position where the module is installed in a backplane, using the white
keys for each code. To determine a unique module code and terminal strip code,
refer to the table below.
