Hardware Reference Guide SST-DN4-104-1 and SST-DN4-104-2

Purpose of this Guide

This guide contains technical and product-related information on the SST-DN4-104-1

and SST-DN4-104-2 network interface cards.

The SST-DN4-104-1 consists of a single DeviceNet network interface (or channel), and the

SST-DN4-104-2 comprises two independent interfaces, controlled by independent CPUs.

Each CPU executes downloadable application firmware modules, which enable application-level

product behavior. For more details, refer to relevant firmware documentation.

Note

An application running on one channel does not affect the performance

of other channels, as it does not share memory or processor resources

with them.

Note

In this manual, the SST-DN4-104-1 and SST-DN4-104-2 will be

referred to as the card, except where product differences apply.

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.

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 PC/104 interface for communication with DeviceNet and other CAN-based

networks. The main features of each channel are:

•16-bit PC/104 interface (compliant with PC/104, specification 2.4). Sixteen bits is the

width of the data bus and does not restrict the card from being used in a 32-bit operating

system.

•64 MHz NIOS Processor

•256 KB of shared RAM

•DeviceNet-compliant 5-pin CAN connector

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

•Bi-color LEDs showing the card’s status

•Isolated physical CAN/DeviceNet layer

•The HOST interface is functionally identical to the DN3-104-2

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

For a comparison of DN4 with DN3, refer to Section E.2, Reference Documents.

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

be connected and powered for the card to communicate on the network. 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 24VDC

supply.

1.5.1.2 CANH, CANL

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

When using the card on DeviceNet with DeviceNet approved cabling, these wires will already

be a twisted pair with the proper DeviceNet impedance.

1.5.1.3 SHIELD

This is the shield connector. This terminal is “snubbed” to the PC/104 chassis ground via a

1M-ohm resistor, through the PC/104 standoffs connected to holes H1 and H2.

Note

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

in the network.

Note

PC-104 specifies that hole H1 be connected to chassis ground. If you’re

using the second channel, ensure that H2 is connected the same way.

Red

Amber Startup self-test complete, no firmware loaded. The

firmware must be reloaded (refer to Section 4.1,

HEALTH or PWR LED is Red).

Note

If the HLTH LED is flashing, there may have been a startup failure.

For more details, refer to Section A.3, Fatal Hardware Self-Test Flash

Codes.

1.5.2.3 COMM LED

The COMM LED indicates the network status. This LED’s meaning and behavior are

determined by the currently loaded firmware module. Refer to the module’s reference

guide for more details.
