SST-DN4-PCU Hardware Reference Guide

Purpose of this Guide

This guide contains technical and product-related information on the SST-DN4-PCU

network interface card.

The SST-DN4-PCU consists of a single independent DeviceNet network interface (or channel),

controlled by an embedded CPU. The CPU executes downloadable application firmware

modules,

which enable application-level product behavior. For more details, refer to relevant

firmware documentation.

Note

In this manual, the SST-DN4-PCU will be referred to as the card.

Using this Guide

If you are running a 3rd party application or writing your own application using the card’s DLL

calls, the sections of interest in this guide will be “Card Overview”, “Installation” and potentially

“Troubleshooting”. If you are writing your own application in a non-Windows environment

(interfacing directly with the card’s memory registers), we recommend that you read the whole

guide.

SST-DN4-PCU Hardware Reference Guide

1.1 Warnings and Cautions

The card is an electrical component and must be treated with the following precautions:

Warning

Only qualified electrical personnel familiar with the construction/

operation of this equipment and the hazards involved should install,

adjust, operate, and/or service this equipment. Read and understand this

guide in its entirety before proceeding. Failure to observe this precaution

could result in severe bodily injury or, in extreme cases, loss of life.

Warning

You must provide an external, hard-wired emergency stop circuit

outside the programmable controller circuitry. This circuit must disable

the system in case of improper operation. Uncontrolled machine motion

may result if this procedure is not followed. Failure to observe this

precaution could result in bodily injury.

Caution

The card contains static-sensitive components. Careless handling may

severely damage the card. Do not touch any of the connectors or pins on

the card. When not in use, the card should be stored in an anti-static bag.

Failure to observe this precaution could result in damage to or

destruction of the equipment.

1.2 Card Features

The card is a PCI interface for communication with DeviceNet and other CAN-based networks.

The main features of each channel are:

•32-bit PCI interface (fully compatible with PCI v2.3)

•Half height short PCI card

•64 MHz NIOS Processor

•256 KB of shared RAM

•DeviceNet-compliant 5-pin CAN connector

•Data rate of up to 1M baud for CAN, and 125K, 250K and 500K for DeviceNet

•Bi-color LEDs showing card status

•Isolated CAN physical layer

•Compatible with CAN specification 2.0 part A and part B

1.3 Byte Ordering

The card uses Intel-style (little endian) byte ordering for multi-byte entities LSB-low address and

MSB-high address. If your host system uses Motorola (big endian) byte ordering (MSB-low

address and LSB-high address), you must compensate for byte ordering in software.

The following language macro will compensate for byte ordering in a 16-bit data entity:

#define SWAP_WORD (WordData) ((WordData<<8) | (WordData>>8))

1.4 DN4 Compatibility Overview

For a comparison of DN4 with DN3 and DNP, refer to Section D.2, Reference Documents.

The following table outlines the requirements of different PCI revisions and the PCI

requirements of the card.

2.2 Required Required Supported Supported

2.3 Required Required Supported Not supported

SST Product

SST-DN4-PCU Optional Required 2Supported 2Supported

1 The card requires only 5V to be supplied by the motherboard. Because 3.3V

supply voltage is optional in PCI specification revision 2.1, the card may not function in

some PCI 2.1-compliant motherboards.

2The card will auto-detect the motherboard PCI I/O signaling level and adjust its signaling level

accordingly, allowing it to function in PCI systems that support either 5V or 3.3V I/O signaling

levels.

Summary

The card’s compatibility can be summarized as follows:

•It will operate in PCI v2.2- and v2.3-compliant systems

1.5.1 CAN Connector

The 5-pin connector is a standard removable connector that conforms to the standard DeviceNet

pinout. Pin numbers, names, and color codes are identified in the figure below.

These terminals provide power to the isolated section of the network interface, and must be

connected in order for the card to function. On DeviceNet networks, they connect directly to the

red (V+) and black (V-) wires of the DeviceNet cable. On non-powered CAN networks, they

must be connected to an external 11-24VDC supply.

1.5.1.2 CANH, CANL

These are the CAN communication bus signal terminals. Use only shielded twisted pair cable.

1.5.1.3 SHIELD

This is the shield connector. This terminal is “snubbed” to the PC/PCI chassis ground via a

1M-ohm resistor.

According to the DeviceNet specification, the snubber circuit can be

omitted if the card has no local connection to ground.

Note

The shield should be connected directly to earth ground at only one

point in the network. Refer to Section 2.4, Connecting to a Network,

for more information.
