2 Safety instructions
These instructions contain texts and figures concerning the correct handling of the
device and must be read before installation or use�
Observe the operating instructions� Non-observance of the instructions, operation
which is not in accordance with use as prescribed below, wrong installation or
incorrect handling can seriously affect the safety of operators and machinery�
►Prepare installation
►Disconnect the power supply of the device�
►Ensure that devices cannot be accidentally restarted�
►Verify safe isolation from the supply�
►Earth and short circuit�
►Cover or enclose adjacent units that are live�
►Follow the specific mounting instructions of the device�
►Only suitably qualified personnel in accordance with EN 50 110-1/-2 (VDC
0105 part 100) is permitted to work on this device/system�
►Before installation and before touching the device ensure that you are free of
electrostatic charge�
►The funtional earth (FE) must be connected to the protective earth (PE) or to
the potential equalisation� The system installer is responsible for implementing
this connection�
►Connecting cables and signal lines must be installed in such a manner that
inductive or capacitive interference do not impair the automatic functions�
►Install automation equipment and related operating elements in such a way that
they are protected against unintentional operation�
►Suitable safety hardware and software measures should be implemented for
the I/O interface so that a line or wire breakage on the signal side does not
result in undefined states in the automation device�
►Ensure a reliable electrical isolation of the low voltage for the 24 V supply�
Only use power supplies compliant with IEC 60 364-4-41 or HD 384�4�41 S2
(VDE 0100 part 410) �
►Fluctuations or deviations of the mains voltage from the rated value must not
exceed the tolerance limits specified in the technical data, otherwise this may
cause malfunction and dangerous operation�
►E-stop devices to IEC/EN 60 204-1 must be effective in all operating modes of
the automation device� Unlatching the e-stop devices must not cause restart�

Field modules DP

►Devices that are designed for mounting in housings or control cabinets must
only be operated and controlled after they have been installed with the housing
closed� Desktop or portable units must only be operated and controlled in
enclosed housings�
►Measures should be taken to ensure the proper restart of programs interrupted
after a voltage dip or failure� This should not cause dangerous operating states
even for a short time� If necessary, an emergency stop must be carried out�
►Wherever faults in the automation system may cause personal injuries or
damage to property, external measures must be implemented to ensure a safe
operating state in the event of a fault or malfunction (e�g� by means of separate
limit switches, mechanical interlocks etc�)
►The electrical installation must be carried out in accordance with the relevant
regulations (e�g� with regard to cable cross-sections, fuses, PE)�
►All work relating to transport, installation, commissioning and maintenance
must only be carried out by qualified personnel� (IEC 60 364 or HD 384 or
DIN VDE 0100 and national work safety regulations have to be observed)�
►All shrouds and doors must be kept closed during operation�
3 Documentation
This documentation relates to the hardware and firmware status at the time of
editing this manual� The features of the devices are continuously developed further
and improved�
3.1 Firmware and hardware status
3.1.1 Downward compatibility
The modules are downward compatible� Older modules cannot, however,
feature the same characteristics as new module versions� However, existing
characteristics have been retained so that older modules can always be replaced
with the new ones�
The documentation describes the differences between the modules�
The firmware and hardware status of the modules can be taken from the version
number printed on the side of the module� The version number can be identified by
the prefix "D"�

4.2 Fieldbus termination
The bus is terminated using an external terminating resistor� The modules are not
capable of fieldbus termination�
The bus termination must be accomplished externally using a connector with integrated terminating
resistor (E12315) as passive terminating resistor�
4.3 Nominal current consumption of modules connected to PROFIBUS-
DP
It is important to consider the current consumption of the individual modules for
power-feed, module protection and assessment of the voltage drop on the power
cable�
Chapter 7 contains a table with the nominal current consumption of the modules�

4.4 Connection to a Siemens PLC type S7-300
In order to describe the connection of the modules to an S7-300 type Siemens
controller, the software package "SIMATIC Manager" version 5�5 with Service
Pack 2 from the company Siemens is used�
4.4.1 Importing the GSD le
Prior to initial configuration of the system in the hardware configurator of the
software, the GSD files must be imported into the software�
Start the software and proceed as follows to import the above GSx files:
►Open new or existing project�
►Open hardware configurator
Copy the required GSx file to the software via menu item [Options] → [Install GSD

6.1.3 Error causes
Should you have any problems with the module, the status LEDs will provide
information on the probably error cause�
Avoidance of typical errors
Checking the PROFIBUS cabling
A PROFIBUS cable (or a cable segment when using a repeater) can be tested with
a few resistance measurements�
For this, the cable should be disconnected from all stations:
Measurement points Typical resistance
between "A" and "B" at the beginning of the cable approx� 110 Ω
between "A" and "B" at the end of the cable approx� 110 Ω
between "A" at the beginning and "A" at the end of the cable approx� 0 Ω
between "B" at the beginning and "B" at the end of the cable approx� 0 Ω
between shield at the beginning and shield at the end of the cable approx� 0 Ω
If these measurements are successful, the cable is error-free�
Should there be further bus errors, these are usually caused by EMC� Please also observe the instal-
lation guidelines of the PROFIBUS user organisation (www�profibus�com)�
6.2 Error diagnosis via software
In the event of an error, the modules automatically send the diagnostic data to the
DP master�
Please note, that the parameter [IP module diagnostics] of the modules with diagnostic capabilities
must be enabled�
In general, DP masters have the possibility to check by means of a flag in the PLC
whether diagnostic data have changed�
The diagnostic data can then normally be read via a function block� If more
diagnostic data apply than can be transmitted, this will be indicated in the
diagnostic data�
