Easergy P3 protection relays (later called relays) can be
connected to Profibus DP with an external REL52815 (VPA3CG)
Profibus interface module (also called Profibus adapter). The relay

Profibus cable
Profibus devices are connected in a bus structure. Up to 32
stations (master or slaves) can be connected in one segment. The
bus is terminated by an active bus terminator at the beginning and
end of each segment (see Figure 1. Cabling and bus termination).
To ensure error-free operation, both bus terminations must always
be powered. When more than 32 stations are used, repeaters (line
amplifiers) must be used to connect the individual bus segments.
The maximum cable length depends on the transmission speed
and cable type (see
Table 2. Line parameters and Table 3. Line length for different
transmission speeds). The specified cable length can be increased
by the use of repeaters. Using more than three repeaters in a
series is not recommended.

General
REL52815
Profibus is a vendor-independent, open fieldbus standard for a
wide range of applications in manufacturing, process and building
automation. Vendor-independence and openness are guaranteed
by the Profibus standard EN 50 170. With Profibus, devices of
different manufactures can communicate without special interface
adjustments. Profibus can be used for both high-speed, timecritical data transmission and extensive complex communication
tasks. The Profibus family consists of three compatible versions.
Profibus DP
Optimised for high speed and inexpensive hook-up, this Profibus
version is designed especially for communication between
automation control systems and distributed I/O at the device level.
Profibus DP can be used to replace parallel signal transmission
with 24 V or 0 to 20 mA.
Profibus PA
Profibus PA is designed especially for process automation. It
permits sensors and actuators to be connected to one common
bus line even in intrinsically safe areas. Profibus PA permits data
communication and power over the bus using 2-wire technology
according to the international standard IEC 1158-2.
Profibus FMS
Profibus FMS is the general-purpose solution for communication
tasks at the cell level. Powerful FMS services open up a wide
range of applications and provide great flexibility. Profibus FMS
can also be used for extensive and complex communication tasks.
Profibus specifies the technical and functional characteristics of a
serial Fieldbus system with which decentralized digital controllers
can be networked together from the field level to the cell level.
Profibus distinguishes between master devices and slave devices.
Master devices determine the data communication on the bus. A
master can send messages without an external request when it
holds the bus access rights (the token). Masters are also called
active stations in the Profibus protocol.
Slave devices are peripheral devices. Typical slave devices
include input/output devices, valves, drives and measuring
transmitters. They do not have bus access rights and they can
only acknowledge received messages or send messages to the
10

4.2 Profibus User Organization
master when requested to do so. Slaves are also called passive
stations.
4.2.
Profibus User Organization
World market leaders in automation technology have joined
together to form the Profibus User Organization. Since its
establishment, 15 countries have formed national user
organizations. These national organizations have been united
under an organization called Profibus International (PI). The
organization represents the interests of Profibus users and
manufacturers. Together with its members, this association is
pushing to establish the international use of Profibus. Several
hundred companies are members of the association. Their primary
tasks and goals are:
•
joint marketing activities
• public relations work
• spreading of information
• further development of the technology
• preparation of certificates confirming conformance to the
standard
• assignment and administration of the ident numbers
• definition of user profiles
• preparation of testing guidelines for test laboratories
• taking care of members
As a member of the Profibus international organization, you are
kept informed of current developments in the area of Fieldbuses.
Membership is open to all users and manufacturers as well as
technical and scientific institutes.

5.1 Continuous mode with fixed data

Profibus DP device profiles
5.1.
Continuous mode with fixed data set
In this mode, the protection relay is sending a configured set of
parameters continuously to the Profibus DP master.
5.1.1.
Calculation of the Profibus DP buffer length in
continuous mode with fixed data set
The needed buffer length for Profibus DP data transfer depends
on the biggest offset of any activated parameter and the size of
this parameter. The offset and the activation for each available
parameter are configurable.
The relay calculates the needed buffer length. For example, if the
relay’s display shows:
InBuf
OutBuf
32 byte
0 byte,
you have to select the corresponding module “INPUT: 32 Byte”
from the .gsd file (for example VPA_00F7.gsd) when configuring
the Profibus DP master for this relay.
The following example reveals the algorithm used by a relay to
calculate the needed Profibus DP buffer length:
Example:
• The parameter Eimp (imported active energy) has the
biggest offset, 30, of all activated Profibus DP data items
in InBuf.
• The size of Eimp item is 4 bytes.
• The parameter DirectO5C ( Direct Operate Object 5
Close) has the biggest offset,13 , of all activated Profibus
data items in OutBuf.
• The size of DirectO5C is 1 byte.
• Both buffers are forced to the same length.
Input:
Offset of the last occupied byte:
30 + (4 - 1) = 33
Round up to next 2n (n is an integer):
log2 33 = log 33 / log 2 = 5.044.
Round up to next integer → 6.
26 = 64
12
VVPA3CG/EN M/C004
5 Profibus DP device profiles
REL52815
5.2 Request mode
Output:
Offset of the last occupied byte:
13 + (1- 1) = 13
Round up to next 2n (n is an integer):
log2 13 = log 13 / log 2 = 3.700.
Round up to next integer → 4.
24 = 16
After restarting, the relay displays the following buffer sizes:
InBuf
OutBuf
64 byte
64 byte
If both buffers are in use in the continuous mode, the length of the
smaller buffer is forced to match the longer buffer. In the example :
24 = 16 is forced to 26 = 64
Select the corresponding module “INPUT/OUTPUT : 64 Byte” from
the .gsd file (for example VPA_00F7.gsd) when configuring the
Profibus DP master for this relay.
Note!
It is recommended that the maximum size for output buffer in
continuous mode is 64 bytes.
5.2.
Request mode
Using the request mode, it is possible to read all available data
from the relay and still use only a short buffer for Profibus data
transfer. The drawback is the slower overall speed of the data
transfer and the need of increased data processing at the Profibus
master as every data item must be separately requested by the
master from the slave.
Note!
It is not possible to read continuously only one single data item. In
request mode, you have to request at least two items in turn to get
updated data from the relay.
After setting the Profibus driver of the relay into request mode, the
relay is restarted (wait for approximately 30 seconds). After
restarting, the relay ignores parameter offsets and displays the
following fixed buffer sizes:
InBuf
OutBuf
8byte
8byte.
Select the corresponding module “INPUT/OUTPUT:8 Byte” from
the .gsd file (for example VPA_00F7.gsd) when configuring the
Profibus DP master for this relay.

Connecting the interface module to
Easergy P3 Standard
The Profibus interface module VPA-3CG is connected to the
‘REMOTE’ port (connector X5) on an Easergy P3 Standard relay’s
rear panel with the Profibus cable. The X4 (I/O with comms) option
must be either E or F.
The Profibus interface module must be powered from an external
12 V power supply through the cable. The continuous power
consumption is 1W.
See the relay’s user manual for more detailed information on
ordering the communication modules.

6.3.
Connecting the interface module to
Easergy P3 Advanced
The Profibus interface module VPA-3CG can be connected to an
Easergy P3 Advanced relay’s RS-232 connector in slot 6 or slot 9
with the Profibus cable.
The following optional communication modules are needed:
• for slot 6 (option card I), option K
• for slot 9 (communication interface I), option B, C, or D
