OPENNET CONTROLLER USER’S MANUAL 1-1
1: GENERAL INFORMATION
Introduction
This chapter describes general information for understanding the OpenNet Controller and system setups for using the
OpenNet Controller in various ways of communication.
About the OpenNet Controller
IDEC’s OpenNet Controller is a programmable logic controller with enhanced communication capabilities. The OpenNet
Controller
is compatible with world’s three major open networks; INTERBUS, DeviceNet, and LONWORKS. Since appli-
cation of these networks are expanding at a fast pace, the OpenNet Controller is ideal for use in multi-vendor control sys-
tems.
In addition, the OpenNet Controller has user communication functions to communicate with various communication
equipment. Modem communication is also very easy using the built-in modem communication functions to communicate
with remote devices through telephone lines. For these communication applications, the OpenNet Controller CPU module
features two RS232C ports and one RS485 port.
User programs for the OpenNet Controller can be edited using WindLDR on a Windows PC. Since WindLDR can load exist-
ing user programs made for IDEC’s preceding PLCs such as all FA series, MICRO-1, MICRO
3
, and MICRO
3
C, your soft-
ware assets can be used in the new control system.
Digital I/O points can be 480 total at the maximum when using an expansion power supply module.
Program capacity is 16K words (8K steps).
Features
Connect to Open Networks
The OpenNet Controller can be connected to the three major open networks; INTERBUS, DeviceNet, and LONWORKS.
The versatile communication capabilities reduce the time and cost needed when constructing, expanding, or modifying
production lines. Maintenance for communication lines will also become even easier.
High-performance CPU Module
The OpenNet Controller CPU module has multiple functions to work as a brain of the control system connected to the
open networks. Optimum control systems can be made possible using the OpenNet Controller.
Powerful Communication Functions
In addition to connection to the open networks, the OpenNet Controller features three more communication functions.
International Safety Standards and Approvals
The OpenNet Controller is certified by UL and CSA.
Master Station (Remote I/O) INTERBUS
Slave Station DeviceNet, L
ONWORKS
User Communication
The OpenNet Controller can be linked to external RS232C devices such as computers,
modems, printers, and barcode readers, using the user communication function.
Data Link
One OpenNet Controller at the master station can communicate with 31 slave stations
through the RS485 line to exchange data and perform distributed control effectively.
Computer Link
When the OpenNet Controller is connected to a computer, operating status and I/O status
can be monitored on the computer, data in the CPU can be monitored or updated, and user
programs can be downloaded and uploaded. A maximum of 32 OpenNet Controller CPUs can
be connected to one computer in the 1:N computer link system.
