!Danger
indicatesthat death or severe personal injury will result if proper precautions are not taken.
!Warning
indicates that death or severe personal injury may result if proper precautions are not taken.
!Caution
with a safety alert symbol indicates that minor personal injury can result if proper precautions are not
taken.
Caution
without a safety alert symbol indicates that property damage can result if proper precautions are not
taken.
Notice
indicates that an unintended result or situation can occur if the corresponding notice is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of
danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a
warning relating to property damage.
Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation. Commissioning
and operation of a device/system may only be performed by qualified personnel. Within the context of the
safety notices in this documentation qualified persons are defined as persons who are authorized to
commission, ground and label devices, systems and circuits in accordance with established safety
practices and standards.

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:
SThe controller CPU is located centrally.
SThe I/O (input/output) system operates locally in a distributed fashion.
SThe 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.

Figure 1-1 A Typical PROFIBUS-DP Installation
PROFIBUS-DP (DP means distributed I/O) is an open bus system conform-
ing with IEC 61784-1:2002 Ed1 CP 3/1. The PROFIBUS-DP consists of a
DP master and DP slaves.
SDP master: The link between the controller and the distributed I/O sys-
tem is the DP master. The DP master exchanges data with the distributed
I/O system over the PROFIBUS-DP and monitors the field bus.
SDP slave: The I/O devices are connected as DP slaves. DP slaves process
data locally from the sensors and signal control elements in such a man-
ner that they can be transferred over the PROFIBUS-DP field bus.

1.2 What Is the ET 200L Distributed I/O Device?
The ET 200L distributed I/O device is a DP slave within the ET 200 distrib-
uted I/O system, its degree of protection being IP 20.
Owing to its compact and flat design, the ET 200L distributed I/O device is
particularly suitable for applications in which space is at a premium. The
ET 200L distributed I/O device has been designed for the low-end to medium
performance ranges.
The ET 200L block I/O device is not expandable.
The ET 200L consists of a terminal block for the wiring, to which an elec-
tronics block is connected. The electronics block determines the number of
input/output channels.
The ET 200L block I/O device is available with 16 or 32 channels.

The terminal block (TB) is used for mounting the electronics block (EB). It
contains the wiring so that if the electronics block is replaced, leads do not
have to be loosened.
The terminal block is characterized by the following:
SIt can be pre-wired before the electronics block is mounted.
SDepending on the design, wiring can be connected by means of screw-
type or spring terminals.
SIt has a two-wire termination and can be upgraded to a three- or four-wire
termination by using supplementary terminals.
SIt does not contain any active electronic components. The terminal block
cannot therefore be destroyed electrically.
SYou can insert different electronics blocks.
SThere are 16-channel (TB 16L) and 32-channel (TB 32L) terminal blocks.
The electronics block contains the logic circuitry and is inserted into the ter-
minal block and screwed. It is characterized by the following:
SIt defines the number of input/output channels.
SYou do not have to loosen the terminal lead to replace the electronics
block; you merely have to remove the bus connector.
SThe PROFIBUS-DP is connected via a bus connector to the electronics
block.
SYou can set PROFIBUS addresses 1 to 99.
SThere is galvanic isolation between the PROFIBUS-DP and the internal
electronics.
SLEDs are used to display: The voltage supply of the electronics block
(ON), bus faults (BF), group errors (SF; not for ET 200L), the status of
inputs and outputs
SThere is a labeling strip in the electronics block for clear identification of
inputs and outputs. You can order the labeling strip separately (refer to
Appendix A.1).
SA circuit diagram is displayed on the electronics block. The circuit dia-
gram is located beneath the labeling strip.
The internal processing time is < 1ms.

Installation
The ET 200L distributed I/O device has been designed for simple installation
and wiring. To this end, the label of the ET 200L distributed I/O device has
been made self-explanatory.
In this chapter, you will find additional information on installing and wiring
the ET 200L distributed I/O device.
A number of steps are involved in the installation of the ET 200L distributed
I/O device. We suggest you adhere to the following sequence:

2.1 Installing the ET 200L TB 16L/TB 32L Terminal Block and
Supplementary Terminal
In this section, we describe how you install the terminal block and the sup-
plementary terminal.
Install the terminal block on a rail.
SYou install the ET 200L distributed I/O device on a rail conforming with
EN 50022 (357.5 or 3515).
SThe preferred mounting position is horizontal installation on a vertical
wall. All other mounting positions are conceivable.
SYou require a free space on a rail of 145 mm (16 channels) or 191 mm
(32 channels).
SThe minimum installation depth is 82 mm (with an electronics block
installed and an MLFB 6ES7 972-0CA30 0XA0 bus connector connected)
when using a 357,5 mm rail.
SYou require a free space of 35 mm above the terminal block. You require
a free space of 20 mm below the terminal block(when using the 42 mm
single-tier supplementary terminal or the 57 mm two-tier supplementary
terminal).
