Device description
The EMpro energy measuring devices (EEM-MA77x types) are universally deployable,
high-precision, network-compatible measuring devices with LC display, which can measure, evaluate and process voltages and currents in one, two and three-phase power supply
systems. For voltage measurements, up to four inputs are available; for current measurements, up to three inputs are available. You can use EMpro energy measuring devices in
TN and IT systems.
Typical installation locations of EMpro energy measuring devices are:
– Assemblies of switchgear and controlgear, assembly of switchgear and controlgear
systems
– Control panels
– Control desks
To enable versatile use, EMpro energy measuring devices are available for the following installation methods:
– For front panel installation or with DIN rail adapter, with LC display, with control buttons
– For DIN rail installation, with LC display, with control buttons (included in the EMpro
product family, but not described in this user manual)
– For DIN rail installation, without LC display, without control buttons (included in the EMpro product family, but not described in this user manual)
If you use a DIN rail adapter (EEM-MKT-DRA, Order Number 2902078), you can mount
EMpro energy measuring devices for front panel installation on a 35 mm DIN rail.
Your advantages:
– Precise knowledge of load profiles allows load management, optimization of the electrical energy usage and optimization of energy consumption from the public supply network and own production (e.g., CHP, PV system).
– Meaningful load profiles are an important aid for planning system expansions and building new systems.
– Energy costs can be assigned to individual functional divisions or cost centers.
– A transparent overview of the energy flows increases the awareness of energy consumption, uncovers waste of energy and makes it possible to identify energy-intensive
system components and equipment that harbors potential energy savings.
– Critical system states can be detected, reported and registered. Such critical system
states can, e.g., be caused by overload, unbalanced load, undervoltage, voltage and
current distortion by non-linear consumers, etc. Detection of critical system states
makes it possible to quickly react to such states in order to prevent potential decreases
in availability or energy supply failures. When critical system states are detected in time,
measures can be taken to ensure permanent system availability.
– Seamless communication with control systems via Modbus/RTU, Modbus/TCP,
PROFINET and EtherNet/IP™ and with higher-level energy management systems via
standard TCP/IP networks (Ethernet, RJ45)
– Intuitive configuration and operation of EMpro energy measuring devices with four front
buttons or integrated web server

EMpro - multi-functional energy measuring devices for front panel installation
Numerous parameters that are important for operating an electrical system are determined
by means of the voltages and currents measured by the EMpro energy measuring devices.
Apparent power, active power and reactive power are measured in all four quadrants (consumption, supply).
EMpro energy measuring devices have an integrated web server. It enables:
– Convenient configuration
– Data logging
– Mains quality evaluations
– Detailed recording of energy flows
A configurable digital input and a configurable digital output are also available. Communication interfaces to higher-level control systems are integrated in the device, depending on
the type.
Currents can be measured with current transformers or Rogowski coils. If you use Rogowski
coils, you do not need an external measuring transducer. EMpro energy measuring devices
can be connected directly to Rogowski coils from any manufacturer. Different device types
are deployed depending on whether current transformers or Rogowski coils are used. Voltages can be measured directly, or by means of voltage transducers.
Voltages and currents are measured using the principle of true r.m.s. value measurement
(TRMS) up to the 63rd harmonic, which enables detailed assessment of the mains quality.
When EMpro energy measuring devices with LC display are used, it is possible to locally
display measurement values and perform configuration tasks locally by means of buttons.
All EMpro energy measuring devices have a Modbus communication interface and an integrated web server. Other communication interfaces are available, depending on the type.
Via the web server, all relevant measurement values and parameters can be displayed and
the energy measuring devices can be configured. On the web interface, settings can be
configured for the following, among others:
– Grid types
– Average values
– Four energy meters for apparent power, active power, reactive power, consumption/supply
– Energy tariff meter
– Logging
– Alarms and behavior in the event of alarms
– Network (TCP/IP)
– Interfaces with higher-level control systems
– Digital output (with logic functions)
– Digital input
– Impulse counter
– Date/time (realtime clock, SNTP compatible)
– Identifier (of metering point)
– Display

Installation
DANGER: Risk of electric shock
If the device is disconnected, the secondary side of the relevant current transformers
must be short circuited.
Install the current sensors and corresponding measuring devices only when the power
supply of the system is disconnected.
When the current transformer is operated with an open secondary circuit, hazardous voltages may occur at the secondary terminal blocks.
When measuring by means of current transformers or Rogowski coils, the accuracy is
greatly influenced by the quality of the current sensors used.

Statistics
Average values
The device makes it possible to determine average values based on the available measurement data.
The average is generated for the following measurement values:
– Voltages: phase to phase U12, U23, U31
– Voltages: phase to neutral conductor U1, U2, U3
– Frequency
– Currents I1, I2, I3, IN
– Active power: consumption, supply
– Reactive power: consumption, supply
– Apparent power
The measurement values are divided into groups. These groups can be configured independently of each other.
The following groups have been formed:
– Voltages
– Frequency
– Currents
– Power
– Predictions
For each average value, the minimum and maximum averages are always recorded and
displayed. The data can be called up via the web server, the display and via the communication interface.
There are three different types of average value generation:
– AVG over fixed interval
– AVG over rolling interval
– AVG over sliding interval
The average value types are described in the following sections.
The figures show the three different types of average value calculation. Select a time interval that the measuring device will then use for calculating the average.

Modbus
Function
The Modbus protocol defines both a protocol on the application layer and a transmission
protocol. The application layer protocol is identical for all interface versions. The differences
between Modbus/TCP and Modbus/RTU lie in the transmission protocol.
On the application layer, Modbus supplies a 16-bit address space that can be used to address 16-bit registers. Using various function codes, read and write operations can be performed on registers.
For detailed information about the Modbus specification refer to www.modbus.org/.
The EMpro supports the following function codes:
– 03 (0x03) Read holding registers
– 04 (0x04) Read input registers
– 06 (0x06) Write single register
– 16 (0x10) Write multiple registers
Here, it has to be noted that the device does not differentiate between holding and input registers. Both function codes return the same registers.

11.2.2
Modbus/RTU
In the case of Modbus/RTU, the Modbus application layer protocol is supplemented with
additional information and physically sent via an RS-485 interface. The start and end of a
Modbus message is coordinated by means of timings.
Modbus/RTU describes a master/slave protocol. Here, the EMpro acts as Modbus/RTU
slave. An exception here is the gateway mode.
The additional information consists of a byte for addressing the device. Valid device addresses are in the range from 1-247.
The default setting for the devices is address 1. Address 0 is reserved for broadcast messages in the network and cannot be assigned as an address to a device.
According to the specification, addresses 248-255 are reserved and cannot be assigned to
the device either.
A cyclic redundancy check (CRC) is attached to the Modbus message as additional information. The CRC is used to detect transmission errors. The calculation and the polynomial
used are documented in the Modbus specification.
The Modbus/RTU protocol is supported by all EMpro versions with an RS-485 interface.
11.2.2.1
Topology
The smallest network via RS-485 (Modbus) that makes sense consists of two devices:
– 1 x master 1 x slave
The typical limit is 32 devices.
– 1 x master 31 x slaves
The largest network via RS-485 (Modbus) that makes sense consists of 248 devices, because of the addressing:
– 1 x master 247 x slaves

EMpro - multi-functional energy measuring devices for front panel installation
11.2.3
Modbus/TCP
In the case of Modbus/TCP, a special header (Modbus Application Header [MBAP]) is prefixed to the Modbus message. This Modbus/TCP message is then transmitted via an IPbased network in a TCP frame.
The EMpro acts as Modbus/TCP server and opens port 502 for communication with any
Modbus/TCP clients. This port cannot be configured by the user.
Since TCP is a connection-oriented protocol, a client first has to establish a TCP connection
with the EMpro to exchange data via Modbus/TCP.
The number of Modbus/TCP connections that can be open in parallel on each version of the
EMpro product family is limited to four.
If there are already four open Modbus/TCP connections on the EMpro, additional connection queries on port 502 are rejected.
Additionally, to enable Modbus/TCP communication, the user has to make sure that this
port is enabled in the network.
The MBAP contains a field that is declared as unit identifier in the specification. This unit
identifier is comparable with the device address of Modbus/RTU. However, it is not relevant
for the EMpro in the case of Modbus/TCP and is ignored by the device since through its IP
address the device already has a unique address in a network . An exception applies if the
device is operated in gateway mode (see Section “Modbus gateway” on page 140).
The Modbus TCP specification recommends using 255 as unit identifier for queries.
All EMpro versions support the Modbus TCP protocol.
11.2.4
Modbus gateway
EMpro versions with an RS-485 interface can optionally be operated in gateway mode.
By default upon delivery, the gateway mode is not active. In this case, the device acts as
Modbus TCP server on the Ethernet interface and as Modbus/RTU slave on the RS-485 interface.
When the gateway function is activated, the device behaves as Modbus gateway on the
Ethernet interface and, in parallel, continues to operate as Modbus TCP server (can be
reached via unit identifier == 255).
On the RS-485 interface, the device now acts as Modbus/RTU master. As master, the
EMpro can now independently send queries in the network (note: there must be no other
master in the system).
As Modbus gateway, the device converts an incoming Modbus TCP message (that does
not have the unit identifier 255 in the MBAP header) into a Modbus RTU message and forwards it to the appropriate receiver in the Modbus RTU network. On the TCP side, the unit
identifier is used for addressing the Modbus RTU receiver. In turn, the response is converted from Modbus/RTU format back to Modbus/TCP format and is sent to the querying client as Modbus/TCP response.
Broadcast messages in gateway mode
The Modbus specification does not describe the behavior of a gateway device when the unit
identifier in the MBAP header has a value of 0. In the Modbus/RTU network, this value represents a broadcast message.
There are different interpretations of the behavior of a gateway in this case.
140 / 192
PHOENIX CONTACT
108904_en_00
Communication
The following questions regarding the behavior of a gateway remain open:
– Forwarding the broadcast in the RTU network.
Since there is no broadcast in the case of Modbus/TCP, it is not defined whether or not
the MBAP address 0 is forwarded in the RTU network by the Modbus gateway.
– Response messages with the unit identifier 0.
Neither is there a definition on whether the gateway itself generates an answer to messages with a unit identifier of 0.
By default upon delivery, devices of the EMpro product family behave as follows:
The EMpro does not forward messages with unit identifier 0 to the RTU network as broadcast. Furthermore, the EMpro itself responds to the query as Modbus TCP server.
Timing in gateway mode
As gateway, the EMpro acts as Modbus master on the Modbus/RTU side and forwards queries to the addressed slaves.
As Modbus/RTU master, the device requires a time-out for queries. If this time-out has expired without a response from the Modbus/RTU slave, the gateway replies to the Modbus/TCP client with an error message.
By default upon delivery, the duration for the time-out is 250 ms.
Unsuitable time-out settings both at the gateway and and at the querying Modbus/TCP client can cause unwanted problems.
Problems can occur if the time-out times at the Modbus/TCP client or EMpro in gateway
mode are too short, or if the ratios between these two time-out times are unfavorable.
The time-out setting has to be individually configured based on the application.
Nevertheless, the following recommendations can be given; they should work in normal
cases.
– The default setting of the EMpro is adequate for most applications.
– If there are slaves with slow response times in the RTU network, the time-out setting of
the gateway should be increased.
– If very slow Baud rates are used on the RS-485, the time-out setting of the gateway
should be increased.
– The time-out duration of the querying Modbus/TCP client should always be longer than
that of the gateway.

Data types and registers
The Modbus specifications does not include requirements on how various data types are to
be displayed on the respective register.
The specification only defines that the register has to be represented as “big endian”. This
means that the high byte of a register is sent first, followed by the low byte.
8-bit integer types:
Example: Value = 1 (0x01)

Register table
The register table is available for download from the Phoenix Contact website.
1. Open phoenixcontact.net/products.
2. Enter the order number of your energy measuring device into the search field.
3. In the download area of the product, you will find the register table under “Miscellaneous”.
11.8
Contents of the register table
The register table contains information that concerns the contents and functions of the communication interfaces.
The register table encompasses the entire Modbus register.
To get the PROFINET-specific register, filter the empty cells from the “GSDML Module
Name” column, so that only cells that are filled with content remain.

Register table
Content of the line (CH)
The first line of the register table contains information about the content of the respective
line or column.
H1 … Hn: Heading
An “H” with a number indicates a heading. The number behind it indicates the hierarchical
level.
To keep the register entries structured and readable, they are divided by headings.

R: Register
The “R” stands for Register and designates the lines that each describe a register.
Only lines that also contain registers are relevant for automatic processing of the register table.
U: Unused
The “U” describes unused entries. These can be, e.g., address ranges that do not have a
function (yet) and are reserved.
E: End
The “E” describes the end of the table.
Dec: Decimal address
The second column of the register table contains register addresses in decimal form.
Hex: Hexadecimal address
The third column of the register table contains register addresses in hexadecimal form.
Count
The “Count” column displays the number of registers required for the function described in
this line. The required number is directly dependent on the data type.
Short designation
The “Short designation” column contains the abbreviated designations of the registers. The
short designations are unique, so that all other data can be referenced using the short designations.
Unit
The unit for the process values is given in the “Unit” column. For example, the unit for the
voltages is volt [V].
Divider
The “Divider” column states the divider by which the value is to be divided to get the correct
value. This is necessary, e.g., if the data type is an integer value, but a decimal fraction has
to be entered.
Example:
If the harmonics are specified as percentage with signed integer, but have to be output with
a precision of a tenth of a percent. In this case, for example, 15.2% is used as 152 with divider 10.
R/W: Read/write access
This column specifies which access is permitted for the respective register.
R: Read only
These registers can only be read. Attempting write access to these registers causes an error.

Communication
R/W: Read and write
It is possible to both read and write to these registers.
W: Write only
These registers can only be written. Attempting read access to these registers causes an
error.
W/R0: Write only and read 0
These registers can only be written. Read access to these registers results in a zero as response.
Datatype
This column contains the data type to be used for decoding the contents of each respective
register.
ASCII
Each register (16 Bit) contains two ASCII characters. When the number is entered, the number of individual registers contained in the character string is determined.
Example:
Dez:1234567
Hex: 0X31, 0X32, 0X33, 0X34, 0X35, 0X36, 0X37
Zero-terminated: “12345670”
Hex: 0X31, 0X32, 0X33, 0X34, 0X35, 0X36, 0X37, 0X00
Number of registers = 4: Hex: 0X3231, 0X3433, 0X3534, 0X0037
Bit mask
Each bit (bit 15-bit 0) of the register (16 bit) is evaluated individually.
Example: “Resetting the tariff meter”
Bit 0: Reset tariff 1
Bit 1: Reset tariff 2
Bit 2: Reset tariff 3
Bit 3: Reset tariff 4
An individual tariff meter, or any combination of meters from all tariff meters can be reset.
Bool
This data type makes a logical statement.
0: false
1: true
