Modbus Gateways

The Modbus Protocol Translator Gateways have been specially designed to allow bidirectional control and monitoring of all parameters and functionalities of your building automation projects.

The most advanced configuration tool for protocol integration

Intesis MAPS is a Windows based software tool specifically developed to configure and monitor the new generation of Intesis gateways.

Intesis Modbus Gateways

Our solutions are developed for integrators, designed to be robust so they are reliable in the field and easy to set up.


Modbus TCP & RTU

All Modbus gateways can communicate with Modbus TCP and RTU networks at the same time.



Most I/O Modbus functions supported

Use any I/O function code of the wide range supported by Modbus gateways (1x, 2x, 3x, 4x, 5x, 6x, 15x and 16x).


Multiple data formats

Configure the data length (1, 16, 32, 48 or 64 bits), format (unsigned, signed, float and bitfield) and byte order (big or little endian).


Polling groups

Improve Modbus communications grouping register requests per device, asking multiple register in a single request.

OCPP to Modbus TCP&RTU Gateway

Integrate Electric Vehicles Charging points based on OCPP 1.6 with any Modbus RTU or TCP controller or connect the chargers to an external OCPP Central System (CS) and monitor them via Modbus. This gateway offers 2 type of OCPP functionalities configurable in MAPS tool:

BMS Central System: The gateway makes accessible basic operations of the Charging points from a Modbus PLC, making the BMS the Central System of the EV charging operation.

External OCPP central system: The gateway acts as a bridge between an external OCPP CS and the OCPP chargers, allowing to monitor metering and status information of the connected chargers.


Support for OCPP 1.6 JSON
Support for Modbus RTU and TCP
Flexible Modbus configuration (Baudrate, Data type)
OCPP Scan to search Chargers in the network
Fix Modbus register map
OCPP operations supported in BMS CS mode:
-Authorize, RemoteStart/Stop Transaction, Start/StopTransaction, Local list management, HeartBeat and MeterValues
OCPP readings supported in External CS mode:
- Charger info, availability and MeterValues
Reduced dimensions, compact housing
UL certified



Use Case

Integration of OCPP EV Charging points into a Modbus installation.INMBSOCP0010100


Gateway acting as an OCPP bridge between an external OCPP Central System and OCPP chargers.



This bidirectional gateway provides a straightforward and fast integration thanks to its unique onboard features.

Thanks to its support for the OCPP 1.6 standard and its basic operations, it guarantees a seamless integration with any standard Modbus PLC or controller to work as a stand-alone Central System or connected to an External OCPP Central system.

The configuration is carried out using the Intesis MAPS software. Which allows you to define your own settings for the device. Also, it will be able to download all the available project templates or to import any created/exported project template on your computer.

Modbus logo

Modbus Protocol is a messaging structure developed by Modicon in 1979. It is used to establish master-slave/client-server communication between intelligent devices. For this reason, it is used in innumerable gas and oil and substation applications. But Modbus is not only an industrial protocol. Building, infrastructure, transportation and energy applications also make use of its benefits.

Modbus Protocol Translators

Bring connectivity to you Modbus management system thanks to Intesis Modbus solutions. Connect BACnet, KNX, LonWorks, DALI or M-BUS devices to Modbus systems and extend your building management system capabilities.

Intesis Modbus can act as Modbus RTU device, Modbus TCP device or both.

On the Modbus server versions, the gateway provides server functionality to the BMS or Modbus controller over Modbus TCP through the Ethernet port and over Modbus RTU through the serial port (EIA485 or EIA232).

On the Modbus client versions, the gateway provides client functionality to control Modbus TCP server devices through Ethernet and Modbus RTU devices through the serial port. In such cases, control and monitoring of Modbus devices from BACnet and KNX BMS controllers is possible.

  • Great integration flexibility thanks to KNX TP, RS485, Ethernet, DALI or M-Bus interfaces.
  • Scaled licences per number of datapoints help finding the right gateway version for your project.
  • Modbus advanced functionalities to improve internal and external protocol communications.
  • Modbus template repository with most common Modbus devices and template generator to create your own template devices.
