Safety information for users
VIPA modules make use of highly integrated components in MOS-
technology. These components are extremely sensitive to over-voltages
that can occur during electrostatic discharges.
The following symbol is attached to modules that can be destroyed by
electrostatic discharges:
The symbol is located on the module, the module rack or on packing
material and it indicates the presence of electrostatic sensitive equipment.
It is possible that electrostatic sensitive equipment is destroyed by energies
and voltages that are far less than the human threshold of perception.
These voltages can occur where persons do not discharge themselves
before handling electrostatic sensitive modules and they can damage
components thereby, causing the module to become inoperable or
unusable. Modules that have been damaged by electrostatic discharges
may fail after a temperature change, mechanical shock or changes in the
electrical load.
Only the consequent implementation of protection devices and meticulous
attention to the applicable rules and regulations for handling the respective
equipment can prevent failures of electrostatic sensitive modules.
Modules have to be shipped in the original packing material.
When you are conducting measurements on electrostatic sensitive
modules you should take the following precautions:
• Floating instruments must be discharged before use.
• Instruments must be grounded.
Modifying electrostatic sensitive modules you should only use soldering
irons with grounded tips.
Attention!
Personnel and instruments should be grounded when working on
electrostatic sensitive modules.

System conception
With the deployment of this module, existing PLC-Systems of the AG 115U
series may be changed step by step to Siemens S7.
Here each central controller respectively expansion unit is connected via
Profibus to a subordinate master system by means of the IM 306 DP slave.
Since you have to replace your CPU respectively IM interface connection
by the IM 306 DP slave, a new wiring of the I/O periphery is not necessary.
For the AG-115U the following IM 306 DP slaves from VIPA are possible:
Order number Deployment at ... Interrupt capability
VIPA 306-1LZ00 ... AG-115U CPU slot yes
VIPA 306-1LE00 ... AG-115U IM slot no
• Each AG-115U is treated as a central controller, which is to be
connected via Profibus to a subordinate master system by means of the
IM 306 DP slave.
• In each rack besides the IM 306 DP slave only digital respectively
analog modules are allowed. No further IM interface connections are
permitted. Here a termination connector is always to be used. More
about this may be found at "Installation".
• Due to the data transfer via Profibus maximally 244byte of input data
and 244byte of output data may be transferred.
• The interrupt capability is only supported by deployment of the module
with order number 306-1LZ00.

Basics Profibus
Profibus is an international standard applicable to an open field bus for
building, manufacturing and process automation. Profibus defines the
technical and functional characteristics of a serial field bus system that can
be used to create a low (sensor-/actuator level) or medium (process level)
performance network of programmable logic controllers.
Together with other field bus systems, Profibus has been standardized in
IEC 61158 since 1999. IEC 61158 bears the title "Digital data com-
munication for measurement and control - Field bus for use in industrial
control systems".
Profibus comprises an assortment of compatible versions. The following
details refer to Profibus DP.
Profibus DP-V0 (Decentralized Peripherals) provides the basic functionality
of DP, including cycle data exchange as well as station diagnostic, module
diagnostic and channel-specific diagnostic.
Profibus DP is a special protocol intended mainly for automation tasks in a
manufacturing environment. DP is very fast, offers plug'n'play facilities and
provides a cost-effective alternative to parallel cabling between PLC and
remote I/O. Profibus DP was designed for high-speed cyclical data commu-
nication between bus master and slave systems.
The original version, designed DP-V0, has been expanded to include
version DP-V1, offering acyclic data exchange between master and slave.
DP-V1 contains enhancements geared towards process automation, in
particular acyclic data communication for parameter assignment, operation,
visualization and alarm handling of intelligent field devices, parallel to cycle
user data communication. This permits online access to station using
engineering tools. In addition, DP-V1 defines alarms. Examples for
different types of alarms are status alarm, update alarm and a manu-
facturer-specific alarm.
Please note in operating the DP V1 functionality that your DP master
supports DP-V1 as well. For this you find details in the documentation to
your DP master.

Profibus distinguishes between active stations (master) and passive
stations (slave).
Master devices
Master devices control the data traffic at the bus. It is also possible to
operate with multiple masters on a Profibus. This is referred to as multi-
master operation. The protocol on the bus establishes a logical token ring
between intelligent devices connected to the bus. Only the master, which
that has the token, can communicate with its slaves.
A master is able to issue unsolicited messages if it is in possession of the
access key (token). The Profibus protocol also refers to masters as active
participants.
Slave devices
A Profibus slave acquires data from peripheral equipment, sensors,
actuators and transducers. The Profibus couplers are modular slave
devices, which transfer data between linked periphery and the high-level
master.
In accordance with the Profibus standards these devices have no
bus-access rights. They are only allowed to acknowledge messages or
return messages to a master when this has issued a request. Slaves are
also referred to as passive participants.
The master of the class 1 is a central control that exchanges cyclically
information with the decentral stations (slaves) in a defined message cycle.
Typical MSAC_C1 devices are controls (PLC) or PCs. MSAC_C1 devices
gain active bus access, which allows them to read the measuring values
(inputs) of the field devices and to write the set points (outputs) of the
actuators at a fixed time.
MSAC_C2 are employed for service and diagnostic. Here connected
devices may be configured, measuring values and parameters are
evaluated and device states can be requested. MSAC_C2 devices don’t
need to be connected to the bus system permanently. These also have
active bus access.
Typical MSAC_C2 devices are engineering, project engineering or operator
devices.

HB37E - IM - RE_306-1LE00 - Rev. 09/28 1-7
The bus transfer protocol provides two alternatives for the access to the
bus:
Master communication is also referred to as token-passing procedure. The
token-passing procedure guarantees the accessibility of the bus. The
permission to access the bus is transferred between individual devices in
the form of a "token". The token is a special message that is transferred via
the bus.
When a master is in possession of the token it has the permission to
access the bus and it can communicate with any active or passive device.
The token retention time is defined when the system is configured. Once
the token retention time has expired, the token is passed to the following
master which now has permission to access the bus and may therefore
communicate with any other device.
Data communication between a master and the slaves assigned to it, is
conducted automatically in a predefined and repetitive cycle by the master.
You assign a slave to a specific master when you define the project. You
can also define which DP slaves are included and which are excluded from
the cyclic exchange of data.
Data communication between master and slave can be divided into a
parameterization, a configuration and a data transfer phase. Before a DP
slave is included in the data transfer phase the master checks whether the
defined configuration corresponds with the actual configuration. This check
is performed during the definition and configuration phase. The verification
includes the device type, format and length information as well as the
number of inputs and outputs. In this way a reliable protection from
configuration errors is achieved.
The master handles the transfer of application related data independently
and automatically. You can, however, also send new configuration settings
to a bus coupler.
When the status of the master is DE "Data Exchange" it transmits a new
series of output data to the slave and the reply from the slave contains the
latest input data.
Consistent data is the term used for data that belongs together by virtue of
its contents. This is the high and the low byte of an analog value (word
consistency) as well as the control and status byte along with the
respective parameter word for access to the registers.
The data consistency as applicable to the interaction between the periphery
and the controller is only guaranteed for 1Byte. This means that input and
output of the bits of a byte occurs together. This byte consistency suffices
when digital signals are being processed.
Where the data length exceeds a byte, for example in analog values, the
data consistency must be extended.

Profibus DP provides an extensive set of diagnostic functions for fast error
localization. Diagnostic messages are transferred via the bus and collected
by the master.
DP-V0 provides the basic functionality of DP, including cycle data
exchange as well as station diagnostic, module diagnostic and channel-
specific diagnostic.
Data is transferred cyclically between the DP master and the DP slave by
means of transmit and receive buffers.

The key feature of version DP-V1 is the extended function for acyclic data
communication. This forms the requirement for parameterization and
calibration of the field devices over the bus during runtime and for the
introduction of confirmed alarm messages.
Transmission of acyclic data is executed parallel to cycle data
communication, but with lower priority.

The DPM 1 (Master Class 1) has the token and is able to send messages
to or retrieve them from slave 1, then slave 2, etc. in a fixed sequence until
it reaches the last slave of the current list (MS0 channel); it then passes on
the token to the DPM 2 (Master Class 2). This master can then use the
remaining available time ("gap") of the programmed cycle to set up an
acyclic connection to any slave (e.g. slave 3) to exchange records (MS2
channel); at the end of the current cycle time it returns the token to the
DPM1.
The acyclic exchange of records can last for several scan cycles on their
"gaps"; at the end, the DPM 2 uses the gap to clear the connection.
Similarly as well as the DPM 2, the DPM 1 can also execute acyclic data
exchange with slaves (MS1 channel).

When addressing data, Profibus assumes that the physical structure of the
slaves is modular or it can be structured internally in logical functional units,
so-called modules. This model is also used in the basic DP functions for
cyclic data communication where each module has a constant number of
input-/output bytes that are transmitted in a fixed position in the user data
telegram. The addressing procedure is based on identifiers, which
characterize a module type as input, output or a combination of both. All
identifiers combined produce the configuration of the slave, which is also
checked by the DPM when the system starts up.
The acyclic data communication is also based on this model. All data
blocks enabled for read/write access are also regarded as assigned to the
modules and can be addressed using slot number and index.
The Slot_Number addresses the module and the index addresses the data
blocks of a module. The Slot_Number = 0 addresses data of the Profibus
coupler, Slot_Number > 0 addresses the data of the function modules.

Each data block can be up to 244bytes. In the case of modular devices, the
slot number is assigned to the modules. Compact devices are regarded as
a unit of virtual modules. These can also be addressed whit slot number
and index. Through the length specification in the read/write request, it is
also possible to read/write parts of a data block.
Note!
For the addressing at the deployment of the Siemens SIMATIC manager
the following conventions are valid:
DP slave coupler: Setting of the diagnostic address as ID.
Modules of the DP slave coupler: Setting of the module address as ID. For
an output module you have to set additionally bit 15 of the module address
(e.g. address 0004h becomes 8004h). With a combination module you
have to set the lower one of the two addresses.

Additional available services are shown in following table.
More detailed information to the services and the DP-V0/1 communication -
principles is to find in the Profibus norm IEC 61158.
Services for Acyclic data communication between the
DPM 1 and Slaves
Read The master reads a data block from the slave.
Write The master writes a data block to the slave.
Alarm An alarm is transmitted from the slave to the
master, which explicitly acknowledges receipt.
The slave can only send a new alarm
message after it has received this
acknowledgment; this prevents any alarms
being overwritten.
Alarm_Acknowledge The master acknowledges receipt of an alarm
to the slave.
Status A status message is transmitted from the
slave to the master. There is no acknowledg-
ment.
Data transmission is connection-oriented over a MS1 connection.
This is set up by the DPM 1 and is closely linked to the connection for
cyclic data communication. It can be used by the master, which has
parameterized and configured the respective slave.
Services for Acyclic data communication between the
DPM 2 and Slaves
Initiate Abort Setup and termination of a connection for
acyclic data communication between the
DPM 2 and the Slave
Read The master reads a data block from the slave.
Write The master writes a data block to the slave.
Data_Transport The master can write application-specific data
(specified in profiles) acyclically to the slave
and if required, read data from the slave in the
same cycle.
Data transmission is connection-oriented over a MS2 connection.
This is set up before the start of the acyclic data communication by
the DPM 2 using the Initiate service. The connection is then available
for Read, Write and Data_Transport services. The connection is
terminated correspondingly. A slave can maintain several active MS2
connections simultaneously. A limitation is given by the resources
available in the slave.

Profibus employs screened twisted pair cable on the basis of the RS485
interface. The data transfer rate of the system is limited to a max. of
12Mbaud.
The RS485 interface uses differential voltages. For this reason this kind of
interface is less susceptible to interference than a plain voltage or current
based interface. The network may be configured as linear or as tree
structure. Your Profibus coupler carries a 9pin socket. This socket is used
to connect the Profibus coupler to the Profibus network as a slave.
Due to the bus structure of RS485, any station may be connected or
disconnected without interruptions and a system can be commissioned in
different stages. Extensions to the system do not affect stations that have
already been commissioned. Any failures of stations or new devices are
detected automatically.
Every device on the Profibus is identified by an address. This address must
be an unique number in the bus and with the IM 306 DP slave between 2
and 125.
At the IM 306 DP slave the Profibus address may be set by the address
switch located at the front side of the module. This address must be
assigned during hardware configuration of the master system in the
properties dialog of the slave system.
For the IM 306 DP slave there are GSD files available from VIPA. These
may be downloaded from the "Service" area of www.vipa.de.
The IM 306 DP slave may be configured as DP-V0 or as DP-V1 slave.
Each slave type has its own GSD file.
The assignment of the slave type is shown in the following table:
Slave type GSD file
DP-V0 VI100BB4.GSD
DP-V1 VI110BB4.GSD
Please install the required files in your configuration tool. Details on the
installation of the GSD files are available from the manual supplied with
your configuration tool.
After the installation of the GSD file the IM 306 DP slave may be found in
