Abstract

An input/output module for implementing directions from a controller for sending and receiving signals to and from devices. The input/output module includes a microprocessor for communication with, and receiving programming from the controller. The input/output module further includes device communication connectors, each having number of pins, each pin for interconnection with a cable conductor to a device. The input/output module has an ASIC for each of the pins, providing a controlled interface with the corresponding pin. Each ASIC has interconnection apparatus, selectable by the microprocessor for providing a particular interface with the pin served by the ASIC.

Claims

1. A configurable connectorized system including a module comprising:

(a) a device communication connector apparatus including a connector for connecting a cable between said module and a device; and

(b) directing apparatus responsive to an input signal from a control apparatus for causing said module to place any of a plurality of signals on any of a plurality of connector pins of said connector, wherein said directing apparatus includes at least one ASIC providing a selectable interconnection apparatus to a particular one of said connector pins.

2. A system as recited in claim 1 wherein said module further includes a second connector for connecting a cable between said module and said control apparatus.

3. A system as recited in claim 1 wherein said control apparatus is included in said module.

4. A system as recited in claim 1 wherein said module further includes an internal signal source and said directing apparatus is programmable to connect a signal from said internal signal source to a connector pin.

5. A system as recited in claim 1 wherein the ASIC includes:

(a) a first selectable interconnection apparatus to connect operational power to a first selected connector pin;

(b) a second selectable interconnection apparatus to connect a digital signal to a second selected connector pin; and

(c) a third selectable interconnection apparatus to connect a power supply return to a third selected connector pin.

6. A system as recited in claim 1 wherein the ASIC includes at least one interconnection apparatus having a digital to analog converter.

7. A system as recited in claim 1 wherein the ASIC includes an interconnection apparatus having an analog to digital converter.

8. A system as recited in claim 1 wherein said directing apparatus is programmable to direct said module to output a first signal to said controller wherein said first signal conveys data content of a signal input to said module to a selected one of said connector pins from a device.

9. A system as recited in claim 1 wherein each ASIC includes an interconnection apparatus including a digital to analog converter, and wherein said directing apparatus is programmable to direct reception of a digital signal from said controller and cause said signal to be converted by said digital to analog converter to an analog signal, and to place a copy of said analog signal on a selected one of said connector pins.

10. A system as recited in claim 1 wherein each said ASIC includes an interconnection apparatus including an analog to digital converter, and wherein said directing apparatus is programmable to detect an analog signal on any selected contact of said first connector apparatus and cause said analog to digital converter to convert said signal to a digital signal and output a copy of said digital signal to said controller.

11. A system as recited in claim 1 wherein said directing apparatus is programmable to cause a power supply voltage to be connected to a first selected connector pin of said first connector apparatus, and to cause a power supply return to be connected to a second selected connector pin of said first connector apparatus.

12. A system as recited in claim 1 wherein said directing apparatus includes a microprocessor.

13. A system as recited in claim 11 wherein said module includes a power supply for providing said supply voltage.

14. A system as recited in claim 1 wherein such said ASIC includes a plurality of interconnection apparatuses for transmission of a corresponding plurality of signal types.

15. A system as recited in claim 14 wherein a signal type includes frequency information.

16. A system as recited in claim 15 wherein said frequency information represents serial communication.

17. A system as recited in claim 15 wherein said frequency information is feedback information from a servo motor.

18. A system as recited in claim 1 further comprising a device including an interlock system controlled by a controller providing direction to said module for sending and receiving signals to said interlock system

19. A system as recited in claim 18 wherein said interlock system includes at least one interlock module and at least one sensor interconnected to said module through corresponding said device communication connectors.
