Scope
This document shall discuss the supported features of Profibus DP, how these features are related to the M2000, and the
special considerations and type of data that is accessible over Profibus DP. This document assumes general understanding of
the Profibus DP protocol by the reader. For further information regarding the Profibus DP Protocol, refer to
www.Profibus.com.
The M2000 Profibus DP daughterboard supports Profibus DPV1 protocol. This is an extended protocol that allows for acyclic
communication for parameter configuration.
In addition, the M2000 Profibus DP daughterboard supports PA Profile Version 3.0.
INTRODUCTION
Profibus is an international, vendor-independent, bus standard for a wide range of applications in manufacturing, production,
process and building automation, and other automation control industries.
The Profibus family comprises three types of protocol, Profibus DP, Profibus-PA and Profibus-FMS, and each is used for
different tasks. Only Profibus DP is considered in this document.
Profibus DP (Decentralized Periphery) is a rapid and low cost communication connection designed for high speed data
transmission. Profibus DP is accomplished with an M2000 through a Profibus DP to Modbus RTU signal conversion board,
referred to as the Profibus DP daughterboard throughout the remainder of this document.

SYSTEM CONFIGURATION
The network diagram below illustrates a typical network configuration of Profibus devices with an RS485 interface. The
Profibus devices with an RS485 interface do not need any segment coupler. These devices can connect directly to the Profibus
DP network.
The maximum cable length in a segment depends on the transmission speed. The Profibus DP daughterboard communicates
at speeds from 9.6 kBps to 6 Mbps over distances from 100 to 1200 meters.
Baud Rate (pbs) 9.6 K 19.2 K 93.75 K 187.5 K 500 K 1.5 M 6M
Length (m) 1200 1200 1200 1000 400 200 100
The Profibus DP protocol has two distinct modes of operation—cyclic data-exchange mode and acyclic configuration mode.
Two types of master devices are defined in a DPV1 network.
Figure 5: Typical network configuration
Master Class 1
Master Class 1 devices can read and write to variables within the slave device cyclically. The Master Class 1 device will also
support acyclic read and write services to application parameters in the slave device. The slave device offers such services only
to the master device that has set the device into cyclic data exchange and only when it is in cyclic data exchange.
A Master Class 1 device is typically a process controller (PLC or SPS) that is performing control functions based on
continuously updated measurement variables.
Master Class 2
Master Class 2 devices typically establish connections to the slave device. Through this connection the master device will be
able to manipulate application parameters of the slave device.
A Master Class 2 device is typically a configuration station (Laptop/PC with configuration management software). Master
Class 2 devices are capable of configuring the device and may operate on all network accessible parameters within the
PA profile.
General Station Data (GSD) Files for Master Class 1 Devices
The GSD files contain information that will be needed for project planning of the Profibus communication network and are
downloadable via the internet.
System Conguration
Page 6 January 2022MAG-UM-01409-EN-05

GSD files describe the capabilities of the Profibus DP device. For example, the baud rates supported by the slave device are
listed in the GSD file.
Configuration Type Identity Number GSD File Name
Profibus 3.0 PA Profile Configuration 0x9700 PA139700.GSD
Manufacture Specific Configuration 0x0D01 BD020D01.GSD
Follow the instructions of the vendor PLC or SPS when installing the GSD file into the PLC.
Cyclic Data Exchange
During network configuration the user defines which data should be transferred cyclically to the master from the slave device.
This is performed through the bus configuration tool for the PLC or SPS. Network configuration will be done using one of the
supported GSD files (PA139700.GSD or BD020D01.GSD).
The PA Profile Configuration cyclically transfers the analog input function block as defined by the GSD file, PA139700.GSD. The
Profibus DP daughterboard associates the meter’s flow rate [User Units] with the analog input function block. This is the only
dynamic variable that can be cyclically exchanged using the PA profile configuration.
The Manufacture Specific Configuration allows for selection of up to 11 dynamic variables to be transmitted cyclically. The
table below defines configurable data that can be exchanged cyclically.
Slot Assignment
(see GSD) Dynamic Variable Units Number of Bytes Supported Configurations
1 Flow Rate User Units 5 0x94 or 0x42 84 08 05
2Flow Velocity m/s 4 0x93
3 T1/T+ User Units 4 0x93
4 T2/T– User Units 4 0x93
5 T3/TN User Units 4 0x93
6 Digital Input Status — 2 0x91
7 Flow Direction — 2 0x91
8 Relative Flow Rate % 4 0x93
9Preset Batch Totalizer m34 0x93
10 Preset Batch Totalizer User Units 4 0x93
11 Power Loss Totalizer seconds 4 0x93
Total: 41 bytes (Maximum)
The Profibus DP daughterboard supports zero module configuration (0x00) to allow the possibility of leaving a dynamic
variable out of cyclic data exchange when using manufacture-specific configurations.
MPORTANTI
For both types of supported network configurations, modification of the display units [User Units]
will have an immediate effect on the data transferred over Profibus.
MPORTANTI
For best performance of the Profibus DP daughterboard,
ensure the Modbus RTU baud rate for Port B is set to 38400.
System Conguration
Page 7January 2022 MAG-UM-01409-EN-05

Identity Numbers
The Profibus DP daughterboard is based on the Profibus PA Profile v3.0. The device supports two identity numbers.
• 0x0D01 belongs to GSD file BD020D01.GSD and includes the complete functionality of the M2000.
• 0x9700 is a manufacturer independent identity number and belongs to the GSD file PA139700.GSD. This provides
interchangeability of devices (that is, an exchange of electromagnetic flow meters of different vendors).
Network Baud Rate
After power on, a baud rate search is started to detect the current bus speed. It is not necessary to set the baud rate manually.
If the baud rate is changed during operation, a power cycle of the slave device is required to re-establish communication with
the master.
MPORTANTI
The Profibus DP daughterboard only supports baud rates up to 6 Mbs.
A baud rate of 12 Mbs is not supported.
Slave Device Network Address
A new device will have the address of 126. In order to operate on the network it must be assigned a bus address in the range
of 0 to 125. Normally, the lower addresses will be assigned for master devices. The address may be changed only when the
device is not in cyclic data exchange mode.
There are two ways to commission the network address of the slave device:
• Using Profibus DP
• Using M2000 menu (Port B External Node Address)

Analog Input Functional Block
The Analog Input (AI) function block has a single fixed channel. This fixed channel associates with the Flow Rate [User Units]
parameter. The AI function block operates in modes controlled by a state machine. The modes determine the output (that is,
OUT) from the function block. The following modes are supported:
Mode Output from Function Block Mode Coding
(Hexadecimal)
Out of Service Last output value (when resource states shows a HW Failure). 0x80
Manual Output value set by operator. 0x10
Auto Output value is calculated from the function block input.
(The input may be set by the operator when in simulation). 0x08

Figure 6: Analog input function block structure
OTE:N PV_SCALE, PV_FTIME, OUT_SCALE, UNIT and SIMULATE are programmable function block parameters within the
analog input function block.
The input to the function block is normally taken from an index in the transducer block and is determined by the CHANNEL
parameter (fixed) of Analog Input function block. However, if the operator enables the simulate function, the input value is
taken from the SIMULATE parameter.
In addition, the operator may choose to scale the output into another unit compared to what is given by the measurement
(PV). Normally the OUT value will be given in either % or in the unit of measurement of PV. The scaling is linear and is made
between the PV upper/lower range and the OUT upper/lower range.
MPORTANTI
The PV unit is fixed to the meter’s selected flow unit.
Changing the meter’s flow units will change the PV unit.
After changing the flow unit, review the scaling parameters of the OUT value.
The output from the Analog Input function block is the OUT parameter. The source for the output is determined by the mode
of the function block. The function block is executed as normal in AUTO mode and the function block execution generates
the OUT value. In Out-of-Service mode, the function block execution is stopped and the OUT value remains at the last usable
value. In manual mode, the operator may write directly to the OUT value and force the output to a value.
A first order low-pass filter may be used. PV_FTIME is the damping factor of the filter. This value represents the time when the
OUT value has reached 63% of the final value after an input step.

There are four configurable alarm levels: Low Alarm, Low Warning, High Alarm, and High Warning. When the OUT value has
exceeded one of the alarm levels, then the status of the OUT value is changed to signal the event.
The output value (OUT) consists of 5 bytes: a 4 byte float value (defined according to IEEE Standard 745) followed by a 1 byte
status value.
MPORTANTI
The only way to check the quality of the transmitted measured values is to monitor the status value.
A value will be transmitted even if the status of the measurement value is bad or uncertain.
The supported status values are described in the following table.
