Installation and Wiring

Profibus-DP Configuration

From Profibus-DP point of view the Profibus-DP Slave (PDPS) node
is configured based on a data file (*.GSD) which contains information
of the size and data-structure of the PDPS.

The Master controls the data exchange to all connected slaves.
The slaves’ I/O data are mapped into memory inside the Master
according to the GSD configuration file.

The Profibus User Organization (PNO) registered the required
Profibus ID as: 0587h.

The GSD file is named: PD1_0587.GSD. It can be downloaded from
the Internet either via Allen Bradley Homepage under
http://www/ab.com/drives/Profibus/Index.html or PNO Homepage
under http://www/Profibus.com/downloads.html than GSD Library
/ Rockwell Automation AG and Drives.

A micro floppy disk containing this GSD file is also available on
request from stock (RA catalog number: 160-GSD).

Module Configuration Switches

The PD1 Module utilizes two ten-position rotary switches (see figure
below) to configure the node address. These switches must be set to
match the application settings. Refer to the paragraphs that follow.

Setting the node address – S1 & S2

Before configuring the PD1 module the node address has to be set.
This is done via two rotary switches (S1, S2) on the PD1, which
enable address settings from 0-99 in decimal format.
The address is calculated in the following way:

Address = (S1 x 10) + (S2 x1)

Important: Two identical node addresses are not allowed within one

network section.
