Abstract
A coding system for various I/O module elements of an I/O cabinet assembly is disclosed which is able to identify analog, digital and control I/O modules by appropriate functional representation combined with a distinct color code found on the front of each module and to identify appropriate internal field wiring connections in the identified module by the module identifying color. Each module has a written identification such as A--for analog, D--for digital and C--for control, I--for input, O--for output combined with an appropriate color bar identifying the type of module. Thus process and terminal blocks forming and I/O unit are easily matched for assembly and are easily inserted into an I/O cabinet in the proper location.
