meet the needs of the application without exposing personnel or
equipment to unsafe or inappropriate working conditions.

This manual is provided to assist the user. Every attempt has
been made to assure that the information provided is accurate
and a true reflection of the product’s installation requirements.
In order to assure a complete understanding of the operation of
the 1560-MBP, the user should read all applicable
documentation on the operation of the Allen-Bradley hardware.

Under no conditions will ProSoft Technology, Inc. be responsible
or liable for indirect or consequential damages resulting form
the use or application of the 1560-MBP product.

Reproduction of the contents of this manual, in whole or in part,

or the product may be made at any time. These changes will be
made periodically to correct technical inaccuracies or
typographical errors.

WARNING

The 1560-MBP card will allow remote access to

commands in the Allen-Bradley drives and other

Scanport compatible devices. The User is

Quick Start Guide

Quick Start Guide

In this section we have assembled a simple step-by-step procedure for
installing and making the 1560-MBP unit operational. This discussion
presumes that the application decisions such as Modbus Plus
addressing and hierarchy, SCANpor t cable length, etc. have been
addressed prior to this point.

Step-by-Step

The following steps will allow the 1560-MBP to be setup in the shortest
period of time (the following steps refer to the Allen-Bradley drive
implementation. Similar steps are followed when interfacing to other A-B
Power Division products):

1 Set the dip switches

The 1560-MBP dip switch positions are detailed in Section 3

2 Mount the 1560-MBP on the DIN rail

See Appendix D for mounting instructions.

3 Connect power to the 1560-MBP

Refer to Section 3

4 Setup the Drive hardware

Refer to the appropriate drive manual to connect control and
power to the drive. This aspect of the drive installation is out
of the scope of this manual.

5 Setup the Drive parameters

See Appendix B of the manual to setup the drive parameters

6 Install the SCANport cable between the drive and the

1560-MBP.

7 Connect the Modbus Plus communication cable between

the host system and the 1560-MBP. The procedure follows
standard Modbus Plus cabling practices.

2 Modbus Plus Port Functionality

2.1 Modbus Plus Communications

The 1560-MBP Modbus Plus card supports the Modbus Plus
protocol using proprietary technology licensed from Schneider
Automation. With the Modbus Plus capability, the module is
able to communicate data from Allen-Bradley SCANport
compatible devices to a Modbus Plus host PLC, and vice-versa.

The following discusses the functional capabilities of the 1560­MBP card.

2.1.1 Supported MSTR Programming Commands

The 1560-MBP uses several of the available MSTR ladder
logic commands to transfer data when using a Modicon PLC.
These are overviewed below:

Read Data: The following types of data read commands are
supported:

MSTR Type 2 Read Data

This command reads data from any place within the
Modbus Register map. This command allows a Modbus
host to selectively read data from the 1560-MBP as
required for the application.

MSTR Type 6 Read Global Data

This command gets data from the Global Data being sent
from the 1560-MBP. The 1560-MBP returns 2 to 10 words
of Global data. This is the fastest method of reading

values from the MBP.
Write Data: The following data write commands are supported:
MSTR Type 1 Write Data

This command writes data to any place within the 1560-

MBP Modbus Register map. This command can be used to

selectively write configuration values to the SCANport

device. In addition, if the Global Data Command Enable dip

switch is disabled, this command can be used to write to

the SCANport Control and Reference words (Modbus

addresses 40001 to 40010).

8

Chapter 2 — Modbus Plus Port Functionality

MSTR Type 5 Write Global Data
This command is used in a host processor to ‘publish’ Global
Data which all slaves on the Modbus Plus highway may
access.The 1560-MBP units can be configured to read the
Control and Reference values from this Global Data table.

2.1.2 Modbus Register Map

A pre-defined register map has been provided in the 1560­MBP unit. This map is detailed in Appendix A, and shown
below. The full memory map is dependent on the A-B device
which is connected to the 1560-MBP unit.

On power-up, the 1560-MBP unit polls the remote device
and determines the maximum number of parameters that
exist in the SCANport device. If the number is greater than
2000 the parameter list is limited to 2000.

using a MSTR Type 6 instruction or Peer Cop (see Appendix
C), or an MSTR Type 2 data read.

3.1.2 Dip Switch Configuration

Configuration of the 1560-MBP consists of setting up some
dip switches. The dip switches are as follows:

Please note that dip switch configuration is read

by the 1560-MBP during the power up process.

Power must be cycled if dip switches are changed
