Data transfer via communication ports

This instruction is used to send data when an external device (computer, measuring instrument,

bar code reader, etc.) has been connected to the specified RS232C port. If applied to the CPU's

COM port, it also clears the receive buffer (see page 746), resets the "reception done flag" and

allows further reception of data.

This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which

is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the

"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears

under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming

area to open the list of recently used elements.
