# Universal Communication Modules (UCM)
Universal Communication Modules (UCM) serve to translate the protocols of individual connected energy devices into a unified one. This is achieved via extensions that deliver data to the Enapter Gateway and Cloud through a secure wireless connection.
Each Enapter UCM runs Blueprint. Enapter Blueprints is a technology that allows integration of various devices (electrolysers, power meters, inverters, batteries, sensors, etc.) into the Enapter Cloud platform with Lua scripts and YAML configuration.

# Software UCMs
Enapter Virtual UCM - ENP-VIRTUAL
Pure Software implementation of the UCM which is running on Enapter Gateway to support Ethernet, Modbus TCP, SNMP, HTTP devices integration such as Solar Inverters, AHU, Charge Controllers, DC Generators, Batteries and others.
Enapter Standalone UCM - ENP-STANDALONE
Pure Software implementation of the UCM which is running in Python environment on any computer and operation system as well as docker container. It used to create custom integrations of any complexity.
# Hardware UCMs
The RS-485 Module used to read data from devices such as inverters, ventilation systems, valves, irradiance sensors, power meters and others. The RS-485 Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
The RS-232 Module is used to read data from devices such as inverters, ventilation systems, valves, irradiance sensors, power meters and others. The RS-232 Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
The CAN Bus Module is used to read data from devices such as vehicles, inverters, ventilation systems, valves, irradiance sensors, power meters and others. The CAN Bus Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
The Relay Module is used to control of a low-power load without high inrush currents. For example: a normal closed valve, a normal open valve, signal lamps or intermediate contactors. The Relay Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
The Analog Output Module is used to control analog devices with a 0…10 V signal using RS-485 interface or Wireless connection. For example: a valve, a sensor or a dimmer. The Analog Output Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
The Analog Input Module is used to receive data from analog devices with a -50…+50 V signal using RS-485 interface or Wireless connection. For example: a valve, a sensor and others. The Analog Input Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
The Analog Input Module is used to receive data from analog devices with a 0…20 mA signal, RS-485 interface and Wireless connection is used for communication with the module. For example: a valve, a sensor and others. The Analog Input Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
Digital Input Module is used to monitor the status of discrete signals such as contactors, relays and others. ENP-DI7 Module can work in wet or dry contact modes (set by the jumper inside the module). The Digital Input Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
