Safety Notes!
Before starting the installation
Disconnect the power supply of the device.
Ensure that devices cannot be accidentally restarted.
Verify isolation from the supply.
Earth and short circuit.
Cover or enclose neighboring units that are live.
Follow the engineering instructions of the device concerned.
Only suitably qualified personnel in accordance with EN 50 110-1/-2 (VDE 0 105 Part 100) may work on
this device/system.
Before installation and before touching the device ensure that you are free of electrostatic charge.
The functional earth (FE) must be connected to the protective earth (PE) or to the potential equalization.
The system installer is responsible for implementing this connection.
Connecting cables and signal lines should be installed so that inductive or capacitive interference do not
impair the automation functions.
Install automation devices and related operating elements in such a way that they are well 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 devices.
Ensure a reliable electrical isolation of the low voltage for the 24 volt supply. Only use power supply units
complying with IEC 60 364-4-41 (VDE 0 100 Part 410) or HD 384.4.41 S2.
Deviations of the mains voltage from the rated value must not exceed the tolerance limits given in the
specifications, otherwise this may cause malfunction and dangerous operation.
Emergency stop devices complying with IEC/EN 60 204-1 must be effective in all operating modes of the
automation devices. Unlatching the emergency-stop devices must not cause restart.
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, emergency-
stop devices should be implemented.
Wherever faults in the automation system may cause damage to persons or property, external measures
must be implemented to ensure a safe operating state in the event of a fault or malfunction (for example,
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 and HD 384 and national work safety regulations).
All shrouds and doors must be kept closed during operation.

PROFIBUS-DPV1
D300956 0210 - BL67/BL20 - DPV11-2
General
PROFIBUS-DPV1 is an enhancement of PROFIBUS-DP which provides the possibility of acyclic data commu-
nication.
A cyclic and centrally directed data transfer between master and slaves is characteristic for the standard
functions of PROFIBUS-DP. A Class1 mater (PLC) controls the cyclic exchange of process data with the slaves.
The data exchange is carried out in rotation and in a defined order. The data which have to be transmitted
are projected beforehand.
Via acyclic communication functions, PROFIBUS-DPV1 now offers the possibility to transmit data to the slave
in addition to the cyclic process data.

D300956 0210 - BL67/BL20 - DPV1 1-3
Acyclic data transfer
1
Acyclic data transfer
The need for acylcic data transfer exists wherever slave devices which provide several parameterization
options have to be parameterized during operation.
Typical examples are the parameters of a drive, like limit values, rotational speed or torque, operation mode
and the generation of an error list.
Acyclic services are handled with low priority, paralelly and additionally to the cylcic process data transfer.
The negative influence on the speed of the high-priority process data transfer, shall thus be minimized.
DPV1-functions
The DPV1-functions consist basically of the services "Read" and "Write". The master uses these services for
read- or write access to data blocks in PROFIBUS.
In addition to that, an "intiate" and "abord"-service for the connection management, a "data-transport"-
service for the exchange of large data packages and the "alarm"-and "status"-services for the transmission
of alarm messages have been defined.
DPM1 versus DPM2
PROFIBUS-DPV1 differentiates between two master classes.
An automation system (PLC), which generally controls the basic cyclic process data transfer with standard
DP-functions, is defined as Class1-master. A Class1-master can use DPV1-functions optionally.
The new Class2-master is generally an engineering tool which is used for the acyclic data transfer.
The protocol cycle of the DPV1-functions on the field bus depends on the use of a Class1- or a Class2-master.
Note
At present, the BLxx-gateways for DPV1 only support the services "Read" and "Write".

PROFIBUS-DPV1
D300956 0210 - BL67/BL20 - DPV11-4
Addressing the data in DPV1
The data-addressing is done per module by means of the following details:
slot
index
length
The slot-number addresses the module and the index addresses the module’s parameters. Each data block
can have a maximum size of 240 bytes.
In case of a successful data access, the slave sends a positive answer. If the data access failed, a negative
answer which classifies the problem precisely is sent.

BL××-gateways for PROFIBUS-DPV1
D300956 0210 - BL67/BL20 - DPV12-2
Introduction
This chapter contains a description of the characteristics of the BL××-gateways for PROFIBUS-DPV1.
As the DPV1-gateways for BL20 and BL67 do not differ from the DPV0-gateways in their technical data, their
connection options (field bus, power supply), their mechanical mounting etc., only the special features of
the DPV1-gateways are described in the following.
For topics which are DPV0/DPV1-common you will therefore find cross references to the respective docu-
mentation for the DPV0-gateways:

Function
The BL××-DPV1-gateways allow the operation of BL××-modules on PROFIBUS-DPV1. The gateway is the
connection between the I/O-modules and the PROFIBUS-masters (see Chapter 1, PROFIBUS-DPV1).
The gateways regulate the process data between the I/O level and the fieldbus, and generate diagnostic
data for the higher-level master.
Information is made available to the software tool I/O-ASSISTANT via the service interface.
Note
BL×× gateways can only be used as slaves.

Diagnosis
Attention
BL××-DPV0-gateways can not be replaced by the new DPV1-gateways. The devices have differ-
ent indent numbers and different GSD-files.
Note
The new DPV1-gateways allow the DP-standard-diagnosis according to PROFIBUS-DP specifica-
tion.
The diagnosis is not compatible with the diagnosis of the DPV0-gateways.
