Data transfer via communication ports

Part III FP Instructions

EXAMPLE
Send 4 bytes of data without adding an end code:
POU Header
LD Body
ST Body
Preparing the system for the reception of further data
 Communication port of the CPU
In order to receive the next data, reset the receive buffer. This is done automatically when sending
the next data with F159_MTRN:
 Resetting the receive buffer sets the number of bytes received in offset 0 to 0
and moves the write pointer back to offset 1. Subsequent data will be stored in
the receive buffer starting at offset 1. (The receive buffer is not cleared).
 The "reception done" flag turns to FALSE.
To reset the receive buffer without sending further data, execute F159_MTRN (see page 741) with
n_Number = 0.
