Abstract:
A system of properly assembling a plurality of individual control signal and control function components into a selected one of a plurality of electronic I/O block assemblies for mounting in a distributed process control system and which have different control functions and different signal inputs as identified according to identical shorthand and color bar markings on both said control signal and control function components comprising;a control signal connector base having a shorthand notation marked directly thereon to denote its signal inputs and having a color code bar accompanying said shorthand notation to denote which one of said plurality of distinct electronic I/O block assemblies having different control functions said control signal component belongs to;a control function component I/O module having the same short hand notation and color code bar marked directly thereon as said control signal connector base;wherein said control signal connector base and control function I/O module components are connected together into an electronic I/O block assembly only if they both have identical shorthand notations and color code bars to assure that the electronic I/O assembly is one having the same control function and required signal input; andwherein said identical shorthand notations and color code bars are clearly visible on said connector base and said I/O module of said I/O block assembly after they are connected together.
