RS-232C
1:1 Link
No-protocol communications enable sending and receiving data using the
TRANSMIT (TXD(236)) and RECEIVE (RXD(235)) instructions without using
a protocol and without data conversion (e.g., no retry processing, data type
conversion, or process branching based on received data). The communica-
tions mode for the serial port must be set for no-protocol communications in
the PLC Setup.
No-protocol communications are used to send data in one direction to or from
standard devices that have an RS-232C or RS-422A/485 port using TXD(236)
or RXD(235).
Provides high-speed communi-
cations with the CX-Program-
mer.
Enables data exchange with a
PT without communications
programming in the CPU Unit.
(The 1:N NT Link protocol is
used for communications even
for 1:1 connections.)
Enables linking data in a 64-
word Link Area between two
