    Section 7-4 Basic Operating Procedure in No-protocol Mode Note Reception Buffer Timing in No-protocol Mode: If the RXD(235) instruction is sent to the CPU Unit’s built-in serial port, the reception buffer is not cleared after RXD(235) execution. Therefore, multiple RXD(235) instructions can be received over several steps. If the RXD(235)/ RXDU(255) instruction is sent to the serial port of a Serial Communications Board/Unit, the reception buffer is cleared after RXD(235)/RXDU(255) execu- tion.

    CompoWay/F is a protocol used by many OMRON components for serial communications. A host computer of a PLC can function as a host (master) to send CompoWay/F commands (message frames) to OMRON compo- nents, which function as slaves. The components will return responses to these commands. Using CompoWay/ F commands, the host can read/write data, settings, and operating status to control the operation of the com- ponents.
