1. About This Manual

This manual is intended for those who have a sufficient knowledge about weighing

instruments and PROFIBUS.

For general information regarding PROFIBUS, specifications, wiring, installation and

operation, refer to PROFIBUS-related technical books.

For information on PROFIBUS or PROFIBUS products, contact your local

PROFIBUS Organization or PROFIBUS distributor.

When configuring a network, use cables and connectors designed for PROFIBUS

products.

When configuring PROFIBUS, a GSD file with device information specific to the

slave device is required. The GSD file is available on our website. Download it as

necessary.

2. Introduction

The AD-4408A functions as a slave device of PROFIBUS when the PROFIBUS

interface module (AX-ABCC-PROFI) is installed.

Using this interface, a PLC can control the AD-4408A and read the indicated values

from the AD-4408A.

Two methods of controling the AD-4408A by the PLC memory are available;

handling bits directly and using commands.

NOTE: The PROFIBUS interface module, when installed into the AD-4408A, uses

12 bytes (OUT) and 20 bytes (IN) of the PLC memory. So, use much care

when assigning areas, not to overlap with other slave devices.

Except during weighing or when weighing is possible, all of the IN data

should be zero.

Memory map and check modes vary with the interface module installed.

This manual describes performances when the PROFIBUS interface

module is installed.

When other modules are installed, refer to the relevant instruction manual.

Instruction manuals for each interface module are available on our

website.
