Definition
Stations Described
in this Manual
The distributed I/O system ET 200 is based on the PROFIBUS standard
(DIN 19245, Part 1) and the PROFIBUS-DP draft standard (DIN 19245,
Part 3).
At SIEMENS, the PROFIBUS is called SINEC L2.
The field bus on which the ET 200 distributed I/O system is based, is a variant
of SINEC L2 called SINEC L2-DP. This version is designed for communication
with the distributed I/O at extremely short response times.
The distributed I/O system comprises active and passive stations, the
SINEC L2-DP field bus and the SINEC L2 network components. The
distributed I/O station is a slave station.

Characteristics of
the ET 200C
The ET 200C Distributed I/O Station has the following characteristics:
Degree of protection IP 66/IP 67
All components of the ET 200C (excluding adapter cables) are designed
with degree of protection IP 66 and 67. However, IP 66 and IP 67 are only
ensured if the installation rules in Section 4.1 are observed.
Compact design
ET 200C is ideal for applications where space is at a premium. A digital
input module with T connector, for example, measures only
289 129 57 mm. An analog module with T connector measures a
mere 289 101 57 mm.
Connections
– Digital inputs and/or digital outputs, analog inputs or analog outputs
– Protective conductor connection for each input/output (digital modules
only)
– 2-wire and 3-wire proximity switches can be connected
Electrical isolation between the SINEC L2-DP field bus and the process
side of the ET 200C modules.
Direct connection of programmer or ET 200 handheld possible (with
adapter cable and programmer with programmer interface module
CP5410-S5DOS/ST)
– For setting the station number (digital modules require ET 200
handheld; analog modules by means of internal DIL switches or the
ET 200 handheld)
– For testing and startup
– Diagnostics
Diagnostics of the inputs/outputs for the following types of fault (can be
switched off with COM ET 200)
– Short-circuit/overload of the sensor supply or outputs
– Wire break in sensor supply (except in DI 16/DO 16 DC 24V/2A)
or at the outputs
– Load voltage of the outputs (digital modules only)
A diagnostic report on defective inputs/outputs can also be output via the
IM 308-B master interface module.

Definition
Advantage
Constraint
Cables
In a configuration with looped field bus and power supply, the individual
modules are connected directly to the field bus.
The power supply is combined with the field bus in a single cable via the
power supply connector.
You do not need a T connector.
The power supply is run over the bus cable, i.e. no external power supply is
required for the slave station.
If a slave station is disconnected from the bus, the “Bus traffic” is interrupted
for slave stations located further down the line.
Since there is then no terminating resistor available, bus traffic might be disturbed for slave stations still connected to the bus.
The level of expansion using one power supply connector is limited
(see Section 2.1.3).
Different types of cable can be used for the various configurations:
Read Section 3.11 if you wish to use prefabricated cables from Siemens.
Read Section 4.3 if you wish to prepare the cables yourself.

Constraint when
Using One Power
Supply Connector
In the configurations using a power supply connector (see Sections 2.1.2 and
2.1.1), the power supply is fed over the bus cable.
This design is limited by the following factors:
If the power supply and the SINEC L2-DP field bus are combined in one
cable, the following values apply for the length of the bus cable between
the power supply connector and the last slave station connected:

2.1.4Configuration without Power Supply Connector
Definition
Advantage
Cables
In a configuration with a separate power supply each slave station is supplied
individually with current. This current supply may not be fed over the bus
cable.
The T connector for connecting SINEC L2-DP is essential for being able to
loop the SINEC L2-DP field bus.
The power supply is not run over the bus (2-core instead of 5-core cable).
A slave station can be disconnected at any time from the bus without the
“Bus traffic” being interrupted for slave stations further down the line, since
the field bus is looped via the T connectors.
Different types of cable can be used for the various configurations:
Read Section 3.11 if you wish to use prefabricated cables from Siemens.
Read Section 4.3 if you wish to prepare the cables yourself.
Note
You must prepare the cables yourself for the load voltage supply of
ET 200C; DO 8 DC 24V/2A or ET 200C; DI 16/DO 16 DC 24V/2A
and for separate power supplies (see Section 4.3).

Spur lines are not permitted on the ET 200C except for the programmer or
the ET 200 handheld. This means that the 12-pin plug of the T connector is
always secured directly to the bus connection of a module.

Note the following rules for the external power supply:
Caution
Risk of destroying the ET 200C modules.
Do not run the SINEC L2-DP bus and the external power supply together
through an ET 200C module. If you did, the external power supply would be
looped though the field bus to other ET 200C modules. This could cause the
gradual destruction of the ET 200C modules.
If you connect an external power supply to an ET 200C module, it is
imperative

2.1.5Configuration with Programmer Connector
Definition
Connection of the
Programmer
Configuration
If you want to connect the programmer to the SINEC L2-DP field bus within
the IP 66/IP 67 landscape, you will need a programmer (PG) connector.
In order to connect the programmer to the programmer connector, you will
require two connecting cables:
Adapter cable (see Section 3.13) and
Programmer connecting cable (Order No. 6XV1 830-1AH...)
An ET 200 handheld cannot be connected to the programmer connector. It
can only be plugged into the bus connection of a slave station (via the
adapter cable). Connection of the ET 200 handheld is described in detail in
Chapter 9.1.
A possible configuration with a programmer connector can be seen in
Fig. 2-9.

Rules for
Connecting the
Programmer
Connector
Both the 2-core and the 5-core cable can be connected to the programmer
connector.
A programmer connector can be placed anywhere on the SINEC L2-DP field
bus. The following should be noted here:
The programmer connector should not be located at the end of the bus
cable, otherwise a terminating resistor cannot be fitted.
You can place several programmer connectors on a bus. You can, however,
only connect one programmer to one of the programmer connectors on the
bus since the programmer is a station with the number 0.
The following values apply for the length of the spur line in accordance
with the baud rate on the SINEC L2-DP bus when connecting a
programmer:

Introduction
Both grounded and ungrounded configurations are possible.
The following two sections include a circuit example for
Grounded configuration and
Ungrounded configuration.
The text contains code numbers, which are references to the respective diagram.
Note
We recommend the grounded configuration for analog modules. This
configuration provides additional protection against electromagnetic
interference.

4.2.1Grounded Configuration
Definition
Rules
In a grounded configuration, the ground and PE potentials are connected.
For the grounded configuration, the following must be taken into account:
You must provide a main switch (1) according to VDE 0100 for the
ET 200C modules, the sensors and the actuators.
You need a fuse (2) for the mains connection of the load power supply
unit.
Use a Siemens load power supply unit of the 6EV1 series (see Catalog
ET 1) for power supply and load voltage supply.
If you use any other load power supply (24 V DC), note that the voltage
must be in the range of 20 V DC to 30 V DC (including ripple). The load
power supply must generate a functional extra-low voltage with
protective separation in accordance with VDE 0106, Part 101. If you use
a switched-mode power supply, you will need a back-up capacitor (with a
rating of 200 F per 1 A load current) (3).
You should provide in secondary circuit a connection (4) to the protective
conductor on the load power supply (terminal M).
You need a main power fuse to protect the supply voltage (5).
For both grounded and ungrounded configurations, use a low-resistance
conductor to connect the protective ground (PE) terminal of the ET 200C
modules (digital and analog modules, power supply connector,
programmer connector) to the protective ground conductor or the chassis
ground (machine ground) (6).
4-4
The right-hand side of the power supply connector features a screw for
connecting the protective ground conductor. PE is looped in via the power
supply connector.
In addition, the protective ground conductor must be connected to the PE
pin in the 12-pin round connector or 6-pin round connector. PE pin and
housing are linked internally.
All machine parts must be grounded.
Use a minimum cross-section of 10 mm
ground connections!

4.2.2Ungrounded Configuration
Definition
Rules
In an ungrounded configuration, there is no connection between the load
power supply (M terminal) and the protective ground conductor (PE). The
protective ground conductor loses its protective function.
The internal design of the digital and analog modules is such that the supply
voltage is connected to the protective ground conductor through a capacitor,
in order to dissipate high-frequency interference.
For the ungrounded configuration, the following must be taken into account:
You must provide a main switch (1) according to VDE 0100 for the
ET 200C modules, the sensors and the actuators.
You need a fuse (2) for the mains connection of the load power supply
unit.
Use a Siemens load power supply unit of the 6EV1 series (see Catalog
ET 1) for power supply and load voltage supply.
If you use any other load power supply (24 V DC), note that the voltage
must be in the range of 20 V DC to 30 V DC (including ripple). The load
power supply must generate a functional extra-low voltage with
protective separation in accordance with VDE 0106, Part 101. If you use
a switched-mode power supply, you will need a back-up capacitor (with a
rating of 200 F per 1 A load current) (3).
You need a main power fuse to protect the supply voltage (5).
For both grounded and ungrounded configurations, use a low-resistance
conductor to connect the protective ground (PE) terminal of the ET 200C
modules (digital modules, power supply connector, programmer
connector) to the protective ground conductor or the chassis ground
(mache ground) (6).
The right-hand side of the power supply connector features a screw for
connecting the protective ground conductor. PE is looped in via the power
supply connector.
In addition, the protective ground conductor must be connected to the PE
pin in the 12-pin round connector or 6-pin round connector. PE pin and
housing are linked internally.
You must provide insulation monitoring to ground with voltage clamping
(7).
Warning
!
The ungrounded configuration can be neutralized by grounded machine parts
and grounded electrical devices.
Example: A grounded sensor or actuator links the PE protective ground to
the M potential of the control system.

Resistance
Thermometer,
2-Wire Circuit
The resistance of the resistance thermometer (Pt 100) is measured with the
aid of a 2-wire circuit. A maximum of four Pt 100 thermometers can be connected (1 resistance thermometer per channel group).
The resistance thermometer receives a constant current supply via terminals
CH0
/ CH2+ and CH0– / CH2–. Voltage drops on the measuring lines can
+
falsify the results of measurement. This type of measurement is of practical
value if the precision requirements are low.
The settings of the switches in DIL switch block S4 determine whether measurement is floating or non-floating (see Section 4.4.2).
Note
If a resistance thermometer (Pt100) is used for floating measurement, the
maximum permissible common-mode voltage is U
be overshot relative to M
at any differential input.

Thermometer,
4-Wire Circuit
The resistance of the resistance thermometer (Pt 100) is measured with the
aid of a 4-wire circuit.
The resistance thermometer receives a constant current Ic via terminals CH0
/ CH2+ and CH0– / CH2–. The voltage generated at the resistance thermometer is measured via CH1
/ CH3+ and CH1– / CH3–. In this configuration,
+
voltage fluctuations on the constant-current lines do not falsify the results of
measurement. The measuring inputs are high-ohmic, so the voltage drop on
the measuring lines is negligible.

maximum permissible common-mode voltage is U

at any differential input.
