Communication control circuit between robot controller and vision system

摘要

The present invention relates to a communication control circuit between a robot controller and a vision system. A voltage converting device outputs a converted voltage or converts an electrical signal to ± 12V after inputting a voltage output from the RS232C connector RS422 to a voltage drop. (M1, M2, M3, M4) and the voltage output from the voltage conversion elements (M1, M2, M3, M4) are input to output a plurality of signals as a single signal to the RS-232C connector and RS-422. In order to control the robot smoothly by outputting data on the operating error range of the robot with the differential elements S1, S2, S3, and S4, the voltage is converted so that noise does not occur in the data transmission line. By converting into a differential signal and inputting and outputting the robot, the robot operates smoothly through the control device even if the position is far between the robot and the control device. To provide that effect.
