5-3-1 Access from External Devices via Serial Communications

Access by Programmable Terminal (PT)
Access from a program directly operating a serial port
Access from a program using FinsGateway Serial Communications Unit
The CX-Simulator provides various types of connections via serial commu-
nications according to debugging needs and a protocol to be used.
Serial connection of OMRON's Programmable Terminal (PT) via NT Link al-
lows to debug a ladder program that processes data input to the CX-Simulator
from PT and creates data for PT display.
Serial connection to a program directly operating a computer's COM port via
Host Link between the computers allows to access the CX-Simulator from the
program.
Note Be sure to specify the CX-Simulator's network number and its node number (1
and 10 in default) when performing FINS communications via Host Link.
Note A connection cable for PLC can not be used because the pin arrangement of
the serial port for an IBM PC/AT or compatible computer is different from that
of a PLC. Make a new connection cable according to the pin arrangements for
the computer and the device to be connected.
When connecting a program using FinsGateway serial communications to the
Ladder engine, connection can be made without practical problems for an
Ethernet Unit or a Controller Link Unit as long as the FINS address for the
CX-Simulator Communications Unit of the Ladder Engine is set by the pro-
gram after starting the FinsGateway Virtual Communications Unit.
