Wireless communication for PLC control is supported by pocketPC OPC server software. Recompiled from an earlier Windows CE version, the server software runs on Pocket PCs using Intel’s high-performance X-Scale processor for untethered IEEE 802.11x Wireless Local Area Network (WLAN) communication with PLCs made by Allen-Bradley, Modicon and GE Fanuc.
