Abstract

The IBM 7535/7540 Robot Systems were designed as stand-alone systems. In this configuration the attachment of an IBM PC, a DI/DO Card, a DI/DO Interconnection Box, a DI/DO Logic Card and cabling gives the system the capability to run several different programs. The system control is contained in software (Host Program) which runs in the IBM PC. As seen in the flowchart, a DI/DO interconnection box 1 is connected by cabling to a robot controller 2 and a DI/DO card 3. The use of the DI/DO box 1 and its associated hardware allows the system to interrupt and restart without losing position in the event of robot error. The DI/DO box 1 has a logic card 4 which translates the robot's DO's 24 VDC to 5 VDC for the PC's DI/DO card and translates the PC's 5 VDC to 24 VDC for the robot's DI's.

The IBM 7535/7540 Robot Systems were designed as stand-alone systems. In this configuration the attachment of an IBM PC, a DI/DO Card, a DI/DO Interconnection Box, a DI/DO Logic Card and cabling gives the system the capability to run several different programs. The system control is contained in software (Host Program) which runs in the IBM PC. As seen in the flowchart, a DI/DO interconnection box 1 is connected by cabling to a robot controller 2 and a DI/DO card 3. The use of the DI/DO box 1 and its associated hardware allows the system to interrupt and restart without losing position in the event of robot error. The DI/DO box 1 has a logic card 4 which translates the robot's DO's 24 VDC to 5 VDC for the PC's DI/DO card and translates the PC's 5 VDC to 24 VDC for the robot's DI's. The box also serves as the interconnecting box for all cabling in the system, allowing the probing of all the lines at one location. The robot sensors are located on the manipulator arm (not shown) and the signals are directed to the DI/DO box 1 where they can be distributed to the robot controllers DI or the IBM PC DI/DO card DI's, or both. Utilizing the DI/DO box and associated software enables the robot system to detect and act upon system errors and operator requests. The DI/DO box can be used in any application where a processor needs DI/DO capability with a peripheral. The robot core layup utilizes two...
