2Product Overview
2.1 What are Distributed I/O Stations?
Distributed I/O Stations - Area of Application
When designing a system, the inputs and outputs from and to the process are often
installed in the programmable controller.
When the inputs/outputs are at a distance from the programmable controller, the
wiring involved can be extensive and confusing; electromagnetic interference can
also reduce the reliability.
In such systems, it is often advisable to use distributed I/O stations:
• the control CPU is located centrally
• the I/O devices are distributed on site
• PROFIBUS-DP allows high data transmission rates so that the control CPU and
I/O devices communicate both quickly and reliably.
• less installation effort since less cables are required.

What is PROFIBUS -DP?
PROFIBUS-DP is an open bus system complying with the IEC 61158/EN 50170,
Volume 2, PROFIBUS standard with the "DP" protocol (DP stands for distributed
(peripheral) I/O).
Physically, PROFIBUS-DP is an electrical network based on a shielded twisted pair
or an optical network using fiber optic cable.
The "DP" protocol allows fast, cyclic data exchange between the control CPU and
the distributed I/O devices.
What is PROFIBUS-DP Ex i
In contrast to PROFIBUS-DP, PROFIBUS-DP Ex i is intrinsically save (type of
protection intrinsically safe i). The intrinsic safety is assured by the use of a fieldbus
isolating transformer that acts like a safety barrier.

Product Overview
What are DP Masters and DP Slaves?
The link between the control CPU and the distributed I/O devices is the DP master.
The DP master exchanges data over PROFIBUS-DP with the distributed I/O
devices and monitors PROFIBUS-DP.
The distributed I/O devices (= DP slaves) prepare the data of the encoders and
actuators locally so that they can be transferred to the control CPU over
PROFIBUS-DP.
Which Devices Can Be Connected to PROFIBUS-DP?
A wide variety of devices can be attached to PROFIBUS-DP as DP masters or DP
slaves providing they operate in compliance with the IEC 61158/ EN 50170 ,
Volume 2, PROFIBUS standard. These include the devices of the following product
families:
• SIMATIC S5
• SIMATIC S7/C7
• SIMATIC programming devices/PCs
• SIMATIC HMI (operator control and monitoring devices OP, OS, TD)
• Distributed I/O devices
• Devices from other vendors
Structure of a PROFIBUS-DP Network
The schematic below illustrates the typical structure of a PROFIBUS-DP network.
The DP master is integrated in the relevant device, for example the S7-400 as a
PROFIBUS-DP interface. The ET 200iS distributed I/O stations are connected to
the DP master over PROFIBUS-DP Ex i and PROFIBUS DP.

2.2 What Is the ET 200iS Distributed I/O Station?
Definition
The ET 200iS distributed I/O station is a highly modular and intrinsically safe DP
slave with degree of protections IP 30.
Areas of Application
The ET 200iS distributed I/O station can be used in hazardous areas in zone 1.
The inputs and outputs of the ET 200iS to the actuators/sensors are intrinsically
safe (EEx ia IIC T4 or EEx ib IIC T4).
Of course, the ET 200iS can also be used in zone 2 or in the safe area.
Directly beside the interface module that transfers the data to the DP master, you
can insert almost any combination of I/O modules belonging to the ET 200iS. This
allows you to tailor the station exactly to your needs locally.
Every ET 200iS consists of a power supply module, an interface module, and a
maximum of 32 electronics modules (for example digital electronics modules).
Product Overview
Terminal and Electronics Modules
In principle, the ET 200iS distributed I/O station consists of various passive
terminal modules onto which you plug the electronics modules.
The ET 200iS is connected to the PROFIBUS-DP Ex 1 using a connector on the
terminal module TM-IM. Every ET 200iS is a DP slave on PROFIBUS-DP Ex i.

2.3 ET 200iS in the Hazardous Area
Properties of the Zones
Areas in which there is a risk of explosion are divided into zones. The zones are
distinguished according to the probability of the existence of an explosive
atmosphere.
The ET 200iS can be used in hazardous areas in zone 1, zone 2 (division 2) and in
the safe area.
You can connect intrinsically save encoders, actuators, and HART field devices to
the ET 200iS that are permitted in zone 0, zone 1, zone 2 of the hazardous area
and in the safe area. The encoders, actuators, and HART field devices must be
certified for the relevant zones.
