PROFIBUS-DP-Slave Operating Manual
Introduction
This manual describes the communications software for the:
• PSS(1) DP-S module
and
• PSS SB 3006 DP-S compact programmable safety system.
Separate manuals are available for using the respective programmable
control systems PSS:
• PROFIBUS-DP-Slave Hardware Manual
• PSS SB 3006 DP-S Shortform
• PSS SB 3006 DP-S Installation Manual
To fully understand this manual you will need to be conversant with the
information found in the general documentation for the programmable
control systems PSS (System Manual, Installation Manual for the modular
PSS and the Programming Manual).
Familiarity with general documentation on PROFIBUS (EN 50170 Volume
2 in the current version) is also required in order to understand busspecific processes, configurations and terminology. Familiarity with a
network configuration tool is also required.
This manual is intended for instruction and should be retained for future
reference.
Overview of manual
1 Introduction
The introduction is designed to familiarise you with the contents,
structure and specific order of this manual.
2 Overview
This chapter provides information on the most important features of
the software package and briefly outlines the application area.
3 Intended use

Terminology
This chapter describes the parameters, diagnostics and the
configuration of input and output data.
This chapter describes the commissioning procedure.
This chapter provides information on the parameters and
management of standard function block SB 230.
The example is designed to provide support when linking standard
function block SB 230 into a user program.
• The term "safety system", "system" or "PSS" will be used in this manual
to refer to the programmable control systems PSS. If the description is
only valid for a particular device, the specific product name will be used
(e.g. PSS SB 3006 DP-S, PSS(1) DP-S).
• In this manual, data transfer is always regarded as viewed from the PSS:
input data / receive data is sent from a PROFIBUS subscriber to the
PSS. Output data / send data is sent from the PSS to a PROFIBUS
subscriber.

Definition of symbols
Information in this manual that is of particular importance can be identified
as follows:
DANGER!
This warning must be heeded! It warns of a hazardous situation which
poses an immediate threat of serious injury and death, and indicates
preventive measures that can be taken.
WARNING!
This warning must be heeded! It warns of a hazardous situation that
could lead to serious injury and death, and indicates preventive
measures that can be taken.
CAUTION!
This refers to a hazard that can lead to a less serious or minor injury plus
material damage, and also provides information on preventive measures
that can be taken.
NOTICE
This describes a situation in which the unit(s) could be damaged and also
provides information on preventive measures that can be taken.
INFORMATION
This gives advice on applications and provides information on special
features, as well as highlighting areas within the text that are of particular
importance.

Introduction
Notes
1-4 PROFIBUS-DP-Slave Operating Manual
Overview
This software package connects the PSS(1) DP-S module or compact
programmable safety system PSS SB 3006 DP-S to PROFIBUS-DP. The
PSS connection is in accordance with PROFIBUS specification EN 50170
Volume 2.
Software package
Data exchange via PROFIBUS is a Master-Slave communication. The
maximum length of data to be exchanged is defined in the master data file
(see file PILZ2500.GSD on the disk supplied). Parameters must be set for
the Slave prior to communication. For example, parameters describe
configuration data, the length of input/output data, station address, etc.
Data cannot be exchanged until the Master has received the parameter
data record.
The setting of parameters on the PROFIBUS-DP-Slave is supported by
standard function blocks. All the required parameters are entered in one
data block.
The programmable control systems PSS have been designed for use in
plant and machinery safety circuits. They consist of a failsafe (FS) section
and a standard (ST) section.

PROFIBUS-DP-Slave Operating Manual 2-1
Overview
Functions
Range
The PROFIBUS-DP-Slave supports the following functions:
• Internal system diagnostics
• Device-related diagnostics
• Transfer of max. 488 bytes of user data
INFORMATION
In this manual, data transfer is always regarded as viewed from the PSS:
Input data is sent from the Master to the PSS, output data is sent from the
PSS to the Master.
The software package consists of:
• one disk and
• one operating manual: PROFIBUS-DP-Slave Software
The disk contains:
• Standard function blocks SB 230, SB 231, SB 232
• Master data files:
PILZ2500.GSD (German)
PILZ2500.GSE (English)
PILZ2500.GSF (French)
• One sample program
2-2 PROFIBUS-DP-S -Slave Operating Manual
Intended Use
This software package is designed to connect a programmable control
system PSS to PROFIBUS-DP. It is essential to use a suitable module or
compact safety system.
This software package is intended for use with the following programmable
control systems PSS:
• PSS DP-S module when using a module rack from the PSS 3000 series.
• PSS1 DP-S module when using a module rack from the PSS 3100
series.
• PSS SB 3006 DP-S programmable safety system as a compact device.
The safety systems are passive subscribers (Slaves) on PROFIBUS-DP.
The meet standard EN 50170 Volume 2, PROFIBUS.
Disregard of the information in this manual and use of the software
package outside the specifications described here will be deemed as
improper application.
INFORMATION
This software package is exclusively for use in non-safety-related
applications. It must be used in the standard section of the PSS.
Conditions for operation:
• The module must be installed in accordance with the PROFIBUS DPSlave Hardware Manual and the relevant “Installation Manual” for the
programmable safety system.
• You must be familiar with and adhere to standard EN 50170 Volume 2,
PROFIBUS.
PROFIBUS-DP-Slave Operating Manual 3-1
Intended Use
Standard function block SB 230
SB 230 may be used with the following functions and parameters:
• PROFIBUS-DP connection
• To trigger a slave reset
• To trigger static diagnostics
• Permitted data lengths:
Input data: 0 ... 108 words (set via parameters)
Output data: 0 ... 108 words (set via parameters)
Diagnostic data: 4 ... 35 words (set via parameters)
Configuration data: 1 ... 244 bytes (set via parameters)
