Modbus installation. For this, IntesisBox acts as a Modbus TCP server or Modbus RTU slave device in its Modbus interface, allowing read/write points from the Modbus client device(s). From the M-Bus point of view, IntesisBox acts as a M-Bus level converter and master device (EN-1434-3).
With every read, the new values received are updated in the Intesisbox's memory and become available in the Modbus side. When a change in any point configured as output in IntesisBox is detected (this is written from the Modbus side), the corresponding action in the M-Bus device will be performed.
Connection to the M-Bus is done by EIA485 connection. Notice that the the gateway is also powering the bus, so no extra hardware is required to connect with M-Bus compatible meters or devices. M-Bus signals IntesisBox Modbus Server - M-Bus can read the following type of signals offered by M-Bus devices: - Energy meters: •...

IntesisBox for every one of the signals to integrate. This is explained in more detail in Annex I of this document.
Description IntesisBox acts as a slave device in its Modbus interface, this interface can be the Ethernet port (if using Modbus TCP), or the EIA232 port or the EIA485 port (if using Modbus RTU). To access the points and resources of the IntesisBox from a Modbus Master device, you must specify as the Modbus register addresses, those configured inside IntesisBox corresponding to M-Bus signals.
Every point defined in the gateway has the Modbus Format, Point and R/W features associated to it that can be configured. These features are explained in section 5.2.4. Each point defined in IntesisBox has the following Modbus features associated to it: Feature...
By default, the gateway has DHCP enabled. If disabled, the default IP is 192.168.100.246. PortA / MBUS Connect the MBUS bus to connectors A3 (+) and A4 (-) of gateway’s PortA. IntesisBox provides 36VDC M-Bus voltage to the bus. PortB / Modbus RTU Connect the EIA485 bus to connectors B2 (+), B1 (-) and A1 or A2 (SNGD) or to connectors B1 (-), B2 (+) and B3 (SNGD) of gateway’s PortB.
In case of using an EIA485 connection, connect the communication cable coming from the Modbus network to the port marked as Modbus of IntesisBox. Connect the EIA485 bus to connectors B2 (+), B1 (-) and A1 or A2 (SNGD) or to connectors B1 (-), B2 (+) and B3 (SNGD) of gateway’s PortB.
Modbus Server series. The installation procedure and main functions are explained in the IntesisBox MAPS User Manual. This document can be downloaded from the link indicated in the installation sheet supplied with the IntesisBox device or in the product website at www.intesisbox.com In this section, only the specific case of Modbus to M-Bus systems will be covered.
5.2.4 Signals All available objects, Object Instances, its corresponding Modbus register and other main parmaters are listed in the signals tab. More information on each parameter and how to configure it can be found in the IntesisBox MAPS user manual.
If NO is selected, remember that the binary file with the project needs to be generated before the IntesisBox starts to work as expected. 3.- Press the Send File button to send the binary file to the IntesisBox device. The process of file transmission can be monitored in the IntesisBox Communication Console window. IntesisBox will reboot automatically once the new configuration is loaded.
Port B of IntesisBox (More details in section 4). 5. Power up IntesisBox. The supply voltage can be 9 to 30 Vdc or just 24 Vac. Take care of the polarity of the supply voltage applied.
