VI PROFIBUS Communications Module

CHAPTER 1

Introduction

This manual provides information about the PROFIBUS Communications module (MDCOMM-PBUS) and using it with MD65 drives. It is intended for qualified electrical personnel familiar with installing, programming, and maintaining AC drives and networks.

The PROFIBUS module is an embedded communication option for MDI AC drives, such as the MD65 drive. The module is mounted in the drive and receives its required power from the drive.

The module can be used with other products that implement MDI, a peripheral communication interface. Refer to the documentation for your product for specific information about how it works with the module.

1.1 PROFIBUS Module Features

The PROFIBUS module features the following:

• The low seven bits of 8-bit DIP switch let you set a node address,

and the MSB bit provides write access for the Flash update of module firmware.

• Depending on the jumper position, “1X” or “5X”, the two operation

modes “Single” and “Multiple” are supported:

• In Single Drive Mode (default mode), the module

represents a single drive on one node and can support one external peripheral (for example, an OIM) over MDI.

• In Multi-Drive Mode, the module represents up to 5 drives

on one node daisy-chained over the RS-485 interface. In this case, the unit will not operate with MDI peripheral devices such as the OIM or the MDCOMM-232.

• Status indicators that report the status of the drive

communications, module, and network.

• The I/O messages (i.e. Control/Status, Reference/Feedback) will

be exchanged with Profibus master in every bus cycle. I/O configuration is fixed and Datalinks are not supported.

• The slave device’ s parameters on the PROFIBUS netw ork can be

configured and monitored using explicit messaging.

Introduction 1-1

• User-defined fault actions determine how the module and MD65

drive respond to communication disruptions (faults) on the network and controllers in idle mode.

• For Single Drive mode, the slave device’s parameters on the

Profibus network can be configured and monitored by the software tool V*S Utilities.

Installing the PROFIBUS Module 3-3

Step 2. Verify the Network Baud rate, which is set by the network

master and depends on cable length.

The MDCOMM-PBUS module uses the Auto-Baud and supports the following different data rates: 9.6 kpbs, 19.2 kpbs, 45.45 kpbs, 93.75 kpbs, 187.5kpbs, 500 kpbs, 1.5 Mpbs, 3 Mpbs, 6 Mpbs, and 12 Mpbs.

The Auto-Baud function allows the module to recognize the current baud rate and sets itself to the transmission rate by the master automatically. After detecting the correct baud rate, the baud rate that was found is monitored continuously. Auto-Baud is always active.

Step 3. Set the Byte Swap jumper J3, which determines the Intel

or Motorola (position SWAP) data format depending on the corresponding PLC. See Figure 3.1.

Step 4. Verify that the jumper J2 is in position “1X” for Single
