1.1 What Is the ET 200 Distributed I/O System?
When a system is installed, the input/output modules are normally installed centrally in the programmable logic controller.
If inputs and outputs are made at long distances from the programmable logic controller, there may be long runs of cabling which are not immediately com- prehensible, and electromagnetic interference may impair reliability.
In such systems, we recommend you to use the ET 200 distributed I/O sys- tem:
S The controller CPU is located centrally.
S The I/O (input/output) system operates locally in a distributed fashion.
S The ET 200 high-performance bus system ensures that the CPU and I/O system communicate with each other without problems owing to its high data transfer rates.
The ET 200 distributed I/O system consists of active (master) and passive (slave) nodes that are interconnected via the PROFIBUS-DP.

3.2 Configuring the Electrical Installation
In this section, you will find information on the overall installation of an ET 200L distributed I/O device on a grounded supply (TN-S system). The specific topics discussed are:
S Circuit-breaking devices, short-circuit and overload protection in accor- dance with DIN VDE 0100 and DIN VDE 0113
S Load current power supplies and load circuits.
With grounded supplies, the neutral conductor of the system is grounded. A mere ground fault between a live conductor and ground or a grounded section of the plant causes the protective devices to trip.
Different components and protective measures are specified for erecting a complete plant. The types of component and the degree to which the protec- tive measures are binding depend on the DIN VDE regulation that applies to the installation of your plant. The following table refers to Figure 3-1.

If the output tolerances are ex- ceeded, we recommend that you install a back-up capacitor. Rat- ing: 200 mF per 1 A load current (with full-wave rectification).
Load circuits should be grounded.
Fault-free operating reliability is ensured by the common reference potential (ground). Install a detachable connection to the protective conductor on the external power supply (terminal L or M) or on the isolation transformer (Fig- ure 3-1, ). This measure makes it simpler for you to locate ground faults in the power distribution system.
You will find notes on EMC-compatible installation and wiring in the manual for the DP master you are using or for the host system.
Take into account the following notes on EMC-compatible installation of the ET 200L distributed I/O device:
S We recommend that you place the cable shield of the PROFIBUS-DP on both sides of a shield bus.
S The chassis ground and the ground terminal are interconnected in the ET 200L distributed I/O device. Connect the ground terminal of the ET 200L distributed I/O device using a copper cable of at least 2.5 mm2
to the central grounding point in the installation cabinet.
