J Other Protocols
OMRON provides all of the capabilities and capacity
you need for the advanced programming required for
Human-Machine Interfaces (HMI), communications,
data processing, and other required applications.
Host Links
Host Link (C-mode) commands or FINS commands
placed within host link headers and terminators can be
sent to a host computer to read/write I/O memory, read/
control the operating mode, and perform other opera-
tions for the PLC.
Unsolicited messages can also be sent from the PLC to
the host computer by sending FINS commands from
the ladder program using the SEND(090), RECV(098),
and CMND(490) instructions.
1:N NT Links
The PLC can be connected to an Omron Operator
Interface Terminal via RS-232C or RS422A/485 ports; I/O
memory in the PLC can be allocated to various Operator
Interface Terminal functions, including status control
areas, status notifications areas, touch switches, lamps,
memory tables, and other objects.
Addition of High-Speed NT Links
High-speed NT Links (three times faster than conventional
host link transmissions) are possible with the NS Series
and version 2 of the NT631 and NT31 Series. This speed
is particularly important when connecting to more than one
Operator Interface Terminal.

J Serial Communications Protocols
Serial Communications instructions (TXD and RXD)
for communications ports can be used for simple data
transfers, such as to input data from bar code readers
or output data to a printer. Start/end codes can be
specified, and RS, CS, and other control signals can
be handled. (Serial Communications instructions can
only be used with the built
