Product overview
1.1 What are distributed I/O stations?
Distributed I/O systems – Field of application
Many systems are configured with a centralized process I/O system in the local
PLC.
Greater distances between remote I/O and the PLC can result in badly arranged
and extensive wiring. Also, electromagnetic interference may reduce reliabilty.
Plants of this type are suitable for operation with distributed I/O systems:
• local controlling CPU
• distributed I/O systems (inputs and outputs) operate at remote locations
• the high–performance PROFIBUS-DP provides high data transmission rates for
trouble–free communication between the controlling CPU and the I/O systems.
What is PROFIBUS–DP?
PROFIBUS-DP is an open bus system according to the IEC 61784-1:2002 Ed1CP
3/1 standard with a “DP” transfer protocol (DP stands for distributed periphery, or
distributed I/O).
PROFIBUS-DP is physically an electrical network that is based on shielded twisted
pair cables or optical waveguide networking.
The ”DP” protocol allows fast, cyclic data exchange between the controlling CPU
and distributed I/O systems.
What are DP masters and DP slaves?
The DP master forms the interface between the controlling CPU and the
distributed I/O system. The DP master exchanges data with distributed I/O
systems via PROFIBUS-DP and monitors the PROFIBUS DP.
Distributed I/O systems (= DP slaves) prepare sensors and actuator data locally
for their transfer to the PLC via PROFIBUS DP.
Which devices can I connect to PROFIBUS-DP?
A wide range of devices can be connected on the PROFIBUS-DP as DP masters
or DP slaves, provided that they operate in accordance with IEC 61784-1:2002
Ed1 CP 3/1. Among others, devices from the following product families can be
used:

• SIMATIC S5
• SIMATIC S7/M7/C7
• SIMATIC programming devices/PCs
• SIMATIC HMI (operator control and monitoring stations OP, OS, TD)
• Devices from other vendors

The figure below shows you a typical PROFIBUS DP network structure. The DP
masters are integrated in the corresponding unit, e.g. the S7-400 or S7-300 is
equipped with a PROFIBUS-DP interface. The DP slaves, namely the distributed
I/O, are interconnected to the DP masters via PROFIBUS DP.

Definition: Grounded powersupply
The neutral conductor of grounded power supplies is connected to ground. Any
ground fault at a live conductor or grounded part of the system will trigger a
response of the protection devices.
Components and protective measures
Vario1us components and protective devices are mandatory for plant/system
installation. The type of components and the binding character of the regulations
for protective measures depends on the DIN VDE regulation that applies to your
plant installation. The table below refers to Figure 3-1.
