Abstract:
A control system comprising:a control section provided with a microprocessor; an axis control circuit connected to the microprocessor, the axis control circuit controlling a robot; an operating section provided with an input/output card interface enabling connection of an input/output card containing a device to control the robot; and a communication circuit for performing communications between said control section and said operating section, wherein said control section comprises a first serial communications interface connected to said microprocessor via a first communications control circuit; said operating section comprises a second serial communications interface connected to said input/output card interface via a second communications control circuit; said communications circuit is a serial communications circuit for connecting the first serial communications interface with the second serial communications interface; and said microprocessor directly accesses the input/output card through the first serial communication interface, the second serial communications interface, and the serial communication circuit, to transmit data to/from the input/output card; and said microprocessor access is achieved by the first communication control circuit transmitting the addresses for a read/write request to said serial communication circuit, through said first serial communication interface, based on the access request from said microprocessor.
