Overview and Specifications

This manual provides instructions for installing, programming, and troubleshooting control systems that use the Series 90-30 PROFIBUS slave module, IC693PBS201. It is assumed that you have a basic understanding of Series 90-30 PLCs and are familiar with PROFIBUS-DP protocol.

The Series 90-30 PROFIBUS Slave module enables a Series 90-30 CPU to be a slave on a PROFIBUS DP network and to communicate with a PROFIBUS DP master. It operates as a slave on the network, automatically exchanging data with a master device. The slave module has no bus access rights. It can only acknowledge received messages or transmit messages to a master upon request. Its features include:

 ability to read up to 244 bytes of input data from the network, and send up to 244

bytes of output data

 support for all standard PROFIBUS data rates

 PROFIBUS-compliant Module and Network Status LEDs

 an RS-232 serial port (the Service port) for upgrading the firmware

PROFIBUS Basics

PROFIBUS Network Overview

• PROFIBUS is an open, vendor independent FieldBus standard for a wide range of

applications in industrial automation, including motion control.

• PROFIBUS is a dynamic technology that grows functionally while complying with the

European FieldBus Standard EN 50 170.

• PROFIBUS Guidelines and Profiles provide the means for further technical

development based on the ever-changing communication requirements of the networks, systems, and devices used in today's industrial automation applications.

PROFIBUS specifications reference three different protocols to cover a range of industrial requirements:

• PROFIBUS-DP High speed data communication. DP stands for Decentralized

Periphery. In practice, the majority of slave applications are DP applications.

• PROFIBUS-FMS Object oriented general-purpose data communication. FMS

stands for FieldBus Message Specification. FMS protocol devices may exchange data on the same bus used for DP devices.

• PROFIBUS-PA Meets requirements for intrinsic safety and non-intrinsic safety

areas and includes bus powered field devices.

Note: The PROFIBUS logo is a registered trademark of the PROFIBUS International

Organization. Membership in the organization is open to all individuals, companies and organizations. More information about the organization and the protocol is available at http://www.profibus.com

Bus Communication

The PROFIBUS specification defines the technical characteristics of a serial field bus system that links distributed digital controllers on the network, from field level to cell level. PROFIBUS is a multi-master system that allows the joint operation of several automation, engineering or visualization systems with their distributed peripherals on one bus. PROFIBUS distinguishes between the following types of devices:

• Master devices determine the data communication on the bus. A master can send

messages without an external request when it holds the bus access rights (the token). Masters are also called active stations.

• Slave devices include motion controllers, drives, I/O devices, valves, and

transducers. Slaves do not have bus access rights and can only acknowledge received messages or send messages to the master when requested to do so. Slave devices are passive stations and require only small portions of the bus protocol.

The majority of PROFIBUS-DP applications are located at the field level. The field level typically includes slave devices such as the S2K motion controller station and host devices like PLC or PC control systems for the PROFIBUS-DP master station. Operator interfaces and DCS type systems usually operate at the cell level.

Network Topology

A PROFIBUS-DP network may have up to 127 stations (address 0-126), however address 126 is reserved for commissioning purposes. The bus system must be sub-divided into individual segments to handle this many participants. These segments are linked by repeaters. The function of a repeater is to condition the serial signal to allow connection of segments. In practice, both regenerating and non-regenerating repeaters may be used. Regenerating repeaters actually condition the signal to allow increased range of the bus.

Up to 32 stations are allowed per segment and the repeater counts as a station address.

A specialized “link” segment consisting only of optical fiber modem repeaters may be used to span long distances. Plastic fiber optic segments are typically 50 meters or less while glass fiber, optic segments may extend several kilometers.

The user assigns a unique PROFIBUS station address to identify each master, slave, or repeater in the entire network. Each participant on the bus must have a unique station address.

Network Connectors

PROFIBUS connections are created with a 9 pin sub-D connector. A minimum connection consists of a shielded twisted-pair cable (shield to pin 1 and twisted-pair wires to pins 3 and 8) with terminating connections in the appropriate bus plugs. The pin to signal conventions are described below.
