Appendix A: DeviceNet

Overview

This appendix describes the Gateway's support for Devi-
ceNet and details the configuration steps necessary to
use this feature. It does not provide a detailed descrip-
tion of DeviceNet, but only a brief introduction, neces-
sary to define the terms that are used throughout the
remainder of this document.

Introduction

DeviceNet is a low-level network using the Controller
Area Network (CAN) technology, to provide communica-
tion between a range of industrial devices, from simple
devices such as sensors and actuators, to high-level
devices such as controllers and HMIs.

DeviceNet Port Protocols

The DeviceNet option card has one DeviceNet port. See
F . 30. The port may be configured for various Devi-
IG
ceNet protocols. Contact Graco Technical Assistance for
currently supported protocols.
Also see Appendix A: DeviceNet
cation on page 42.
DeviceNet Option Card Pin Outs
• V-
Position 1 of the pluggable connector provides a
CAN ground connection. This terminal is isolated
from the Graco Gateway.
• CAN_L
Position 2 of the pluggable connector provides the
CAN_L bus line (active low). This terminal is iso-
lated from the Graco Gateway.
• DRAIN (optional)
Position 3 of the pluggable connector is provided for
optional drain connections. This position is available
only to tie drain wires together or to earth ground.
There is no internal connection to earth ground. The
DRAIN position is not connected to any circuitry
internal to the DeviceNet option card.

• CAN_H
Position 4 of the pluggable connector provides the
CAN_H bus line (active high). This terminal is iso-
lated from the Graco Gateway.
• V+ (optional 24 Vdc)
Position 5 of the pluggable connector is provided for
optional 24 Vdc connections. This position is avail-
able only to tie 24 Vdc wires together. The Devi-
ceNet option card neither provides or uses 24 Vdc
power through this connection. The V+ position is
not connected to any circuitry internal to the Devi-
ceNet option card or Graco Gateway.
