ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to modular I/O electrical control assemblies comprised of a processor block and a I/O module and more particularly to systems for color coding I/O blocks to allow a proper assembly of the I/O processor block and I/O module and proper cabinet connecting of same.
2. Description of the Prior Art
In most systems requiring the assembly of individual parts into a system or element of that system a schematic along with an instructional booklet is used. Such a procedure becomes especially burdensom when you begin assembly of electronic control systems such as block I/O cabinetry. These systems first require the assembly of processor blocks and I/O modules into an I/O assembly according to appropriately coordinated identical module functions and a further co-ordination of these modules having the same function for identical type of signal input. As an example, identical digital input-output processor blocks for temperature signals could be mismatched with digital input-output I/O modules for line voltage or pressure signals. The result would be at the least an inoperative system.
Similar problems occur in field wiring the processor blocks of I/O modules which can have up to 24 channels which require specific input or output signals co-ordinated to the I/O block which must be not only identified as inputs or outputs but must also be the right type of inputs or outputs as was explained above.
Thus a foolproof assembly system for I/O block assemblies was needed which would identify each processor block and I/O module by its appropriate function as well as the type of input requiring the noted function to be performed thereon.
BRIEF SUMMARY OF THE INVENTION
The present invention solves the problems associated with prior art I/O system assembly as well as others by providing a label on both the processor block and the I/O module having a shorthand functional representation of the function as well as identifying by a color code the type of signal to be applied to the module. This assures that only identical function modules having identically identified signals shall be assembled into a unit assembly made up of a processor block and an I/O module or unit.
Additionally, the processor block has an internal label which is located next to each field wiring connection thereto and identifies the connection to be made thereto by its input or output function and also by the color code described earlier defining the type of input or output signal to be connected thereto. A scratch pad label is mounted inside a door of the processor block covering the field wiring connections where the wiring label information is repeated and having space provided next to each identified channel for the user to write in further information.
In view of the foregoing it will be understood that one aspect of the present invention is to provide a marking scheme for individual control components which are assembled together which will insure assembly of these components according to identical function performed and specific signal input for the function.
Another aspect of the present invention is to provide a label for assembled components denoting function according to a shorthand notation and input signals according to a color schematic.
Yet another aspect of the present invention is to provide field wiring labels allowing proper field wiring according to input, output and the type of signal applied.
These and other aspects of the present invention will be more fully understood after a review of the following description of the preferred embodiment when considering along with the associated drawings.
