Serial
port 2
No-protocol
Standard devices supporting serial communications
Communicates with standard
devices with an RS-232C or
RS-422A/485 port without a
command–response format.
Instead the TXD(236) and
RXD(235) instructions are exe-
cuted from the program to
transmit data from the trans-
mission port or read data in the
reception port. The frame
headers and end codes can be
specified.
