Introduction
EnOcean to Modbus TCP/IP Gateway –User Manual
V1.7 / 2023-11-01 5/40
1INTRODUCTION
1.1 Description
The EO-MOD-IP device is a gateway between EnOcean and Modbus/IP communication protocols. The
EnOcean is a set of technologies and communication protocol that enables the use of wireless and battery-
free sensors, switches and actuators. The Modbus is a communication protocol that is simple to implement
and is widely used in building automation systems. The EO-MOD-IP gateway can receive data from up to 40
EnOcean devices, store it and provide it through the Modbus interface to other devices connected to the
network. It also allows bidirectional communication of EnOcean actuators such as switches, dimmers or
heating valve controllers.
The first part, the manual describes the hardware of the gateway. Chapter 7 contains brief instructions for
configuring the gateway, especially for connecting EnOcean devices. Chapter 8 describes the Modbus
interface and explains how EnOcean devices are mapped to Modbus registers. For firmware update
procedure refer to Chapter 9.
1.2 Installation instructions
The gateway is fixed by using plastic anchors and Phillips
screws to the wall or solid surfaces of suspended
ceilings making sure that it is in a good radio position for
receiving and transmitting signals. When located in
shielded surfaces, the standard supplied antenna can be
replaced with another permitted antenna type for the
868 MHz frequency with an SMA (Male) connector.
External antenna with cable and magnetic base, type
ANT-A1-SMA868-MAG2M is available at the
manufacturer or distributor.

Hardware Overview
EnOcean to Modbus TCP/IP Gateway –User Manual
V1.7 / 2023-11-01 6/40
2HARDWARE OVERVIEW
On the front panel, there are a power connector, RJ45 Ethernet connector, type B USB connector, antenna
connector and LED indicators. The USB connector can be used for configuration and firmware update, and
is also used by the EO-BAC Tool application. The green POWER terminal block is removable, making it easier
to handle the device when cables are connected.
The LEDs indicate: the connection of power supply
(POWER), activity in the Modbus network (MOD
RX, MOD TX), activity in the EnOcean wireless
network (ENOC), USB communication (USB) and
error states (ERROR). The LEDs are very useful
when testing or commissioning but because the
emitted light can be disruptive during normal
operation, the LEDs can be deactivated (Web UI >
Settings > LED Indication).
There is a switch to the right of the POWER
terminal block that is only accessible after pulling
out the POWER terminal block. This is used to set
the USB interface mode:
•the “HID” position (default) allows the connection of EO-BAC Tool application
•the “MSC” position allows access to filesystem

requirements. The electrical installation must
be in accordance with national requirements
and safety standards.

Configuration
EnOcean to Modbus TCP/IP Gateway –User Manual
V1.7 / 2023-11-01 10/40
7CONFIGURATION
The gateway has an integrated web application (Web UI) that serves to configure it using a web browser.
Alternatively, a desktop application EO-BAC Tool is available at www.firvena.com, ->
SUPPORT/DOWNLOAD/EO-MOD-IP/APPLICATION, it requires USB connection to the gateway and Windows
7 or higher. The use of EO-BAC Tool becomes necessary, among other things, if the password to Web UI has
been forgotten. The following part describes how to open Web UI for the first time.
7.1 Accessing Web Interface
The IP address factory setting is:
Switch on the gateway and connect it to a local network via the
ETHERNET connector or directly to a computer with an Ethernet
adapter. The DHCP client is enabled by default, so the gateway
automatically obtains the IP address and other network parameters
from a DHCP server if available. The gateway signals DHCP success by
shortly turning off the green POWER light.
If the configuration via DHCP fails, because there is no DHCP server in
the network or you connect the gateway directly to a computer, the default network configuration is used
after 10 seconds. In this case, change Ethernet adapter settings so that your computer has the same subnet
mask and a different IP address, e.g. 192.168.1.95.
The Web UI is available on HTTP port 80, if you
know the IP address of the gateway, simply
enter “http://<IP Address>” into the address
bar of your web browser (e.g.
http://192.168.1.90).
The main page opens in “view-only mode”. Login is required for other
pages and configuration changes. The default password is “123”, you can
change it in [Settings > Change Password]. If the password is lost, you need
to perform a factory reset using the EO-BAC Tool.
There are several options to find out the currently valid IP of the gateway:
1. Network Discovery using UPnP
This method is recommended when using the Microsoft Windows
operating system and UPnP messages are allowed in the network to which
the gateway is connected.
Open the Network item in the File Explorer:

Configuration
EnOcean to Modbus TCP/IP Gateway –User Manual
V1.7 / 2023-11-01 11/40
The gateway is under the group “Other Devices”.
The description and IP address of the gateway are
shown. Double click on the device item to open
the Web UI. [Right click > Properties] will display
additional information.
If the gateway is not shown, try to refresh the list:
[Click on the list > press F5 key] or [Right click > Refresh].
2. Using EO-BAC Tool
In the USB HID mode (see Ch. 2), the gateway presents itself as a Custom
HID USB device. Connect the gateway to your computer using USB and
use the EO-BAC Tool.
3. USB MSC
In the USB MSC mode (see Ch. 2), the gateway presents itself as an
external USB drive. Connect the gateway to your computer using USB.
Find a file named NETINFO.TXT in the root directory and open it. The file
contains the current IP address. To access the Web UI, enter the IP address to the address bar of your web
browser.

V1.7 / 2023-11-01 12/40
4. DHCP server
If you have access to the local DHCP server (usually through the configuration interface of your router), the
IP address should be in DHCP clients list, look for the host name “EO-MOD-IP_XXXXXX”. To access the Web UI,
enter the IP address to the address bar of your web browser.
7.2 Web UI
This chapter is a brief guide to the use of the Web UI application.
The Web UI is used to configure the gateway. The main purpose of the application is to manage EnOcean
devices connected to the gateway. The application is also a useful verification tool whereby you can evaluate
whether your system works well. It allows to see the states, measured quantities, communication intervals
or signal strength of the connected EnOcean devices.

7.2.2 Assigning EnOcean elements –unidirectional
This teach-in procedure is only applicable for unidirectional communication when the gateway only receives
data.
Let’s have a humidity sensor (A5-04-01) we want to assign to the channel 1. The procedure is as follows:
1. Click the “Add new” icon, a
dialog box appears.
2. Push the pairing button to
transmit a teach-in telegram.
3. The received telegram is
displayed in the dialog box.
4. Select the channel number 1.
5. Click “Save” to confirm
changes
6. Now the sensor is assigned
to channel 1 and its data is
available through the
Modbus interface.
Optionally, the Label can be set for the device. The Label text is used in the Channel labels registers (see Ch.
8.2.5). If the Label field is left empty, the default text will be used.
The knowledge of EEP allows the gateway to interpret the received data correctly. Some types of EnOcean
devices do not provide the EEP information in their teach-in telegram or even not have a special telegram
for teach-in (e.g. buttons and switches). In that case, the EEP must be set manually, it is usually given by a
label on the device or a datasheet.
Devices can also by assigned manually by entering the ID and EEP.
Click on the channel box to view more settings and status information:

7.2.3 Assigning EnOcean elements –bidirectional
This teach-in procedure is applicable for EnOcean devices with bidirectional communication profiles when
the gateway is supposed to receive data from the device and also transmit data to the assigned device.
Let’s have a valve actuator (A5-20-01) we want to assign to the channel 1. The procedure is as follows:
1. Click the “Add new” icon, a dialog box appears.
2. Check “LRN enable”
3. Select the channel number 1.
Channel 1 is now in the teach-in mode.
4. Push the pairing button to transmit a teach-in telegram from the actuator.
5. Gateway receives the telegram and sends a teach-in response.
6. The device is automatically saved to the selected channel and its data is available through the Modbus
interface.
To change the Label, enter the new text and click “Save”.
Notes:
•The device being assigned usually signals successful teach-in, e.g. by flashing LED. If it signals an error, the
teach-in must be repeated.
7.2.4 Assigning Smart ACK devices
To assign a Smart ACK device to the gateway, the procedure is the same as for bidirectional profiles (7.2.3).
Repeaters are not supported, there must be a direct connection between the gateway and the Smart ACK
device.
7.2.5 Definition of Virtual Device
The gateway can be used to simulate a real EnOcean device. This function is necessary when controlling
actuators that do not implement any bidirectional profile, typically some types of relay switches.
For example, we want to control a relay switch that supports reception of a Door/Window Contact D5-00-
01. The procedure is as follows.

Configuration
EnOcean to Modbus TCP/IP Gateway –User Manual

EnOcean to Modbus TCP/IP Gateway –User Manual
V1.7 / 2023-11-01 18/40
8MODBUS INTERFACE
The gateway is a Modbus TCP/IP server, it processes requests sent by clients. By default, the Modbus server
listens on TCP port 502 and UDP port 502 (there is a limit of four simultaneous TCP connections). Each
Modbus server may provide different services, which are identified by function codes in Modbus. The
definitions of standard services are described by the application layer specification –see [7], for more
information about Modbus over TCP/IP see [8].
This chapter describes how the data of EnOcean devices is translated into the Modbus data model and how
this data can be accessed by standard function codes. A complete list of Modbus registers is also available.
8.1 Mapping of EnOcean Devices
EnOcean devices are mapped as a set of Modbus registers. The gateway can handle up to 40 EnOcean
devices. To assign an EnOcean device, the teach-in procedure has to be carried out (see Ch. 7.2). The
assigned EnOcean devices are identified by Channel (CH1…40) within the gateway, the Channel is selected
by user during teach-in procedure.
Data fields received in a telegram are divided into individual Modbus registers so that they can be accessed
using Modbus standard functions from the network. The gateway contains a database of supported EnOcean
products, the meaning of individual data registers depends on the type of EnOcean device (EEP) that is
assigned to the channel during teach-in procedure.
Three types of data fields are distinguished:
•Numeric value: usually a measured physical quantity such as temperature, humidity, etc.
•Enumeration: defined as a list of items that express a state or configuration of the device
•Boolean: two-state enumeration whose items can be interpreted as true/false, such as on/off,
enabled/disabled, open/closed, etc.
In addition, two directions are distinguished:
•RX: data received by the gateway (incoming telegrams)
•TX: data transmitted by the gateway (outgoing telegrams)

Modbus Interface
EnOcean to Modbus TCP/IP Gateway –User Manual
V1.7 / 2023-11-01 19/40
The data fields are stored internally as Values. The Values are identified by Value index, 15 Values is reserved
per channel (indexes 0 to 14):
The Values from Telegram data range represent a model of EnOcean telegram. For simple devices (such as
sensors with unidirectional communication) the model of telegram can also be assumed to be a model of
EnOcean device. Some more complex EEP definitions consist of several types of telegrams that represent
different commands, so the device cannot be described by a single telegram. Special mapping is created for
these devices.
For direction “RX”, all used Values are mapped to RX Values registers (starting at address 0). For direction
“TX” all used Values are mapped to TX Values registers (starting at address 1000). If the channel is not
occupied the associated Value registers are zeroed.
The mapped data fields from EnOcean telegram are indexed in the same order as they appear in the EEP
definition –see [3].
Besides the data values, there are also helper values for each channel that provide status information:
