Call PNIO_SEND and PNIO_RECV functions to establish data communication between CP343 and S300PLC
Map the sending address, and map the 16 bytes starting from MB10 to the QW address space of the HJ3205D.
Map the receiving address, and map the 16 bytes starting from MB40 to the IW address space of HJ3205D.
