1 Introduction
1.1 Preface
Please read this manual before starting up the interface. Keep the manual in a
place which is accessible to all users at all times.
Please assist us to improve this manual.
Your suggestions will be welcome.
HIf any difficulties should arise during commissioning, you are asked
not to carry out any unauthorized manipulations. You could endan-
ger your rights under the instrument warranty!
Please contact the nearest subsidiary or the main factory in such a
case.
EWhen returning chassis, modules or components, the regulations
of EN 100 015 “Protection of electrostatically sensitive compo-
nents” must be observed. Use only the appropriate ESD packag-
ing for transport.
Please note that we cannot accept any liability for damage caused
by ESD (electrostatic discharge).

2 Profibus description
PROFIBUS is a manufacturer-independent, open fieldbus standard for a wide
range of applications in manufacturing, process and building automation.
Manufacturer independence and openness are ensured by the international
standard EN 50 170.
Using PROFIBUS, devices from different manufacturers can communicate
without any special interface adjustments. PROFIBUS can be employed for
both high-speed time-critical data transmission and extensive, complex com-
munication tasks. The PROFIBUS family consists of three versions.
2.1 Profibus types
The PROFIBUS family
PROFIBUS DP This PROFIBUS version, which is optimized for high speed and low connec-
tion costs, has been especially designed for communication between auto-
mation control systems (PLC) and distributed field devices (typical access
time: < 10msec). PROFIBUS DP can be used to replace conventional, parallel
signal transmission with 24V or 0/4—20mA.
DPV0: cyclic data transfer:
--> is supported by the recorder.
DPV1: cyclic and acyclic data transfer:
--> is not supported by the recorder.
DPV2: slave-to-slave communication takes place in addition to cyclic and
acyclic data transfer:
--> is not supported by the recorder.
PROFIBUS-PA PROFIBUS-PA has been specifically designed for process engineering. It per-
mits the linking of sensors and actuators to a common bus cable, even in haz-
ardous areas. PROFIBUS-PA enables the data communication and energy
supply for devices in two-wire technology according to the international IEC
1158-2 standard.
PROFIBUS-FMS This is the universal solution for communication tasks at cell level (typical ac-
cess time: approx. 100msec). The powerful FMS services open up a wide
range of applications and provide a high degree of flexibility. FMS is also suit-
able for extensive communication tasks.

2.2 RS485 transmission technology
Transmission takes place according to the RS485 standard. It covers all areas
in which a high transmission speed and simple, cost-effective installation are
required. A shielded twisted copper cable with one conductor pair is used.
The bus structure permits addition and removal of stations or step-by-step
commissioning of the system without affecting the other stations. Later expan-
sions have no influence on the stations which are already in operation.
Transmission speeds between 9.6 kbit/sec and 12 Mbit/sec are available. One
uniform transmission speed is selected for all devices on the bus when the
system is commissioned.
Basic features of the RS485 transmission technology
Installation
tips All devices are connected in a bus structure (line). Up to 32 stations (master or slaves) can be linked up in one segment.
The bus is terminated by an active bus terminator at the start and end of each
segment. Both bus terminators must always be powered, to ensure fault-free
operation.
If there are more than 32 users, repeaters must be used to link up the individu-
al bus segments.
Network topology linear bus, active bus termination at both ends,
stub cables are only permissible for baud rates
≤1.5 Mbit/sec.
Medium shielded twisted-pair cable
Number of stations 32 stations in each segment without repeater (line amplifier).
With repeaters, this can be expanded to 126.
Connector preferably 9-pin sub-D connector

2 Profibus description
Cable length The maximum cable length depends on the transmission speed. The cable
length specified can be extended by using repeaters. It is recommended not
to connect more than 3 repeaters in series.
Range based on transmission speed
Cable data These cable length specifications refer to the cable type described below:
Characteristic impedance: 135 — 165 Ω
Capacitance per unit length: < 30 pf/m
Loop resistance: 110 Ω/km
Core dia.: 0.64 mm
Core cross-section: > 0.34 mm²
It is preferable to use a 9-pin sub-D connector for PROFIBUS networks incor-
porating RS485 transmission technology. The pin assignment at the connector
and the wiring are shown at the end of this chapter.
PROFIBUS cables and connectors are supplied by several manufacturers.
Please refer to the PROFIBUS product catalog (www.profibus.com) for types
and addresses of suppliers.
When connecting up the devices, make sure that the data lines are not re-
versed. It is absolutely essential to use shielded data lines. The braided shield
and the screen foil underneath (if present) should be connected to the protec-
tive earth on both sides, and with good conductivity. Furthermore, the data
lines should be routed separately from all high-voltage cables, as far as this is
possible.
As a suitable cable we recommend the following type from Siemens:
