OPENNET CONTROLLER USER’S MANUAL 25-1
25: DEVICENET SLAVE MODULE
Introduction
This chapter describes DeviceNet slave module FC3A-SX5DS1 used with the OpenNet Controller to interface with the
DeviceNet
TM
network, and provides details on the DeviceNet system setup and the DeviceNet slave module specifications.
The OpenNet Controller can be linked to DeviceNet networks. For communication through the DeviceNet network, the
DeviceNet slave module is available. Mounting the DeviceNet slave module beside the OpenNet Controller CPU module
makes a slave station used as an I/O terminal in a DeviceNet network. The slave station can transfer I/O data to and from
the master station just as an ordinary I/O module in a distributed network.
DeviceNet Slave Module Features
Since the DeviceNet slave module conforms to the DeviceNet specifications, the OpenNet Controller can be linked to
DeviceNet networks consisting of DeviceNet compliant products manufactured by many different vendors, such as I/O ter-
minals, sensors, drives, operator interfaces, and barcode readers.
The transmit/receive data quantity can be selected from 0 through 8 bytes (64 bits) in 1-byte increments. One DeviceNet
slave module enables the OpenNet Controller CPU module to transmit 64 bits and receive 64 bits at the maximum to and
from the DeviceNet master station.
About DeviceNet
DeviceNet was originally developed by Allen-Bradley as a network for sensors, actuators, and other discrete devices,
and later the specifications were opened. Now, major automotive manufacturers and various industries employ
DeviceNet networks.
DeviceNet Features
The network configuration is based on the bus system. The basic network consists of a trunkline-dropline topology.
Multi-drop or daisy-chain configuration is also possible.
The DeviceNet protocol is based on CAN (Controller Area Network) which has been widely used for networks on auto-
mobiles, making it possible to configure reliable networks with high noise immunity.
Transmission Distance and Nodes
The maximum transmission distance is 500 meters when using a thick trunk cable at a data rate of 125k baud, and the
maximum quantity of nodes is 64 including a master station.
