In this research, we propose an industrial Wireless Local Area Network (iWLAN) system compatible with asynchronous communication for industrial robots (iRBs) control in factory automation (FA) environments. In FA, iRBs are not only controlled by synchronous communication but also by asynchronous communication. As our conventional system is not compatible with asynchronous communication, it causes delay when iRBs are controlled by asynchronous communication. In order to target iRBs using asynchronous communication, we propose the utilization of specific memory writing technique. The register transfer level (RTL) simulation results show that our proposals can communicate with iRBs in faster throughput, better than the conventional system. Furthermore, the field-programmable gate array (FPGA) implementation are carried out to confirm that motors can be controlled by our iWLAN system compatible with asynchronous communication.
