Industrial Communication

Introduction

Today, the PC assumes a key position in automation technology. Together with a real-time

operating system such as Windows

NT, it creates an ideal hardware platform for control

and visualization of process data. Fieldbus systems with remote input and output modules

are used for the data transfer between the PC and the automation equipment. Advantech

has launched a series of Fieldbus communication interface cards from Hilscher™, a

company with a field-proven record in industrial communication technology. We offer

special interface PC cards, since PCs do not feature a direct link to the Fieldbus. These

intelligent cards manage the entire data transfer so that only useful data are passed onto

the user applications.

The idea behind the “Communication Interface - CIF”, is to provide common access to

the various Fieldbus systems available on the market. We provide a powerful, easy to

handle and reliable solution at a low-cost. Thus, you can concentrate on your applications

and do not need to “reinvent the wheel” when you’re required to use a different Fieldbus

system tomorrow.

We place special value on ease of operation. This includes loadable Firmware, configuration

data that remain even after a power failure, an online RS-232C diagnostic interface and

LED status indicators. Naturally, each card supplied carries the CE mark.

PC Cards in all Formats for the Fieldbus Standards

We supply PC cards with PCI-bus or in the PC/104 and PC/104-Plus format for all leading

Fieldbus systems. Careful component selection and focus of the necessary functions has

resulted in a single-side surface mounted card with a low cost.

Fieldbuses differ from each other in their physical interfaces and capacity spectrums. We

don’t use plug-in modules for adaptation. We provide a dedicated card for the Fieldbus

system, sometimes different ones for Master or Slave functions. Only in this way can we

guarantee you the best performance relationship with the highest degree of reliability.

System Conﬁgurator with an Uniform “look and feel”

All cards are configured using the SyCon

System Configurator. This software has been

coded in C++ and executes under the Windows

95/98/ME and Windows

NT/2000/XP

operating systems.

Graphical input of the individual bus participants, clearly structured menu guidance and

automatic computations of the bus parameters make the configuration a very simple

exercise.

By means of the function interface, other programs can exchange data with the configurator

Fieldbus Communication Overview

and access its database.

The configurator can also be included in your own product as an OEM version.

Uniform and Easy-to-use application Interface

The data exchange between the application and the communication interface takes place

via a dual-port memory. This is a type of memory where read/write accesses are performed

both from the application and from the interface side. A static data model is used for the

dual-port memory. It is uniform for all cards and contains the process image. Commands

and message-oriented data are exchanged using two mailboxes. The entire handshake is

performed in either polling or interrupt mode using only two bytes.

Driver for all Windows

operating systems and Linux

We supply a 32-bit Device Driver, since you cannot access the hardware directly with

modern operating systems. This driver has the same functional interface as our drivers

for DOS. Thus you can access the communication interface using the same C interface

for all operating system.

Support for Three Types of Popular

Fieldbus Communication Interfaces

We support three types of popular fieldbus protocol: PROFIBUS, DeviceNet and CANopen

with PCI-bus or in the PC/104 or PC/104-Plus format.

PROFIBUS™

PROFIBUS is a multi-master system that enables mutual operation of several automation,

engineering or visualization systems on a bus. We supply two PROFIBUS protocol

specifications: PROFIBUS-DP and PROFIBUS-FMS, simultaneously, to satisfy different

requirements.

DeviceNet™

DeviceNet utilizes CAN technology for data transmission. The transmission rates of

DeviceNet are 125, 250 and 500 kBaud. It is one of the most popular networks for

factory automation as it can connect industrial devices to a network at a low cost without

expensive wiring.

CANopen

Controller Area Network (CAN) is a serial network and features quick reaction and a high

degree of reliability. The transmission rates in the CANopen range from 1 kBaud up to

1Mbaud. CANopen is usually used in an embedded network such as machine control

within industries.
