OPENNET CONTROLLER USER’S MANUAL 4-1
4: OPERATION BASICS
Introduction
This chapter describes general information about setting up the basic OpenNet Controller system for programming, start-
ing and stopping OpenNet Controller operation, and introduces simple operating procedures from creating a user program
using WindLDR on a computer to monitoring the OpenNet Controller operation.
Connecting OpenNet Controller to PC (1:1 Computer Link System)
The OpenNet Controller can be connected to an IBM PC or compatible computer in two ways.
Computer Link through RS232C Port 1 or Port 2
When connecting a Windows computer to the RS232C port 1 or port 2 on the OpenNet Controller CPU module, enable the
maintenance mode for the RS232C port.
To enable the maintenance mode for the RS232C port 1, set the DIP switch 2 to OFF.
To enable the maintenance mode for the RS232C port 2, set the DIP switch 3 to OFF.
To set up a 1:1 computer link system, connect a computer to the OpenNet Controller using the computer link cable 4C
(FC2A-KC4C).
Computer Link through RS485 Port
When connecting a Windows computer to the RS485 port on the
OpenNet Controller CPU module, enable the mainte-
nance mode for the RS485 port.
To enable the maintenance mode for the RS485, set the DIP switch 1 to OFF.
To set up a 1:1 computer link system, connect a computer to the OpenNet Controller using the computer link cable 6C
(FC2A-KC6C). An AC adapter is needed to supply 5V DC power to the RS232C/RS485 converter on the computer link
cable 6C. For the applicable output plug of the AC adapter, see page A-5.
