Chapter8 DeviceNet Slave Board
8.1 Overview
If the robot controller has a built-in DeviceNet slave board, it can communicate with
external devices according to the DeviceNet-compliant protocol.
As a slave unit for serial communications which is compliant with the open network
DeviceNet, the robot controller may easily exchange I/O data with a variety of
DeviceNet-compliant control devices of many manufacturers.
8.1.1 Features
(1) DeviceNet-compliant
The DeviceNet is an internationally open network developed by Allen-Bradley and is
designed to allow control devices (e.g., sensors and actuators) to communicate with
each other.
(2) Can be networked with control devices of various manufacturers
The robot controller equipped with DeviceNet slave board can be networked with
DeviceNet-compliant control devices of various domestic and foreign manufacturers
since the communications specifications are open.
(3) Easy wiring and maintenance
The 5-core special cable and detachable connector of the DeviceNet slave board
make it easy to install wiring between nodes (communications units) and
disassembly/restructure the network. This will sharply reduce cost in wiring and
maintenance, as well as making replacement of units easy at the time of failure.
(4) Sufficient number of I/Os
The controller is capable of handling a large quantity of I/O data as listed below.
Further, increase or decrease of the number of user-input I/Os is possible in units of 8
steps.
