====== ibvunit ======

This is a program for the communication of the **IB-System** directly with physical devices through external or internal communication gateways.

The **ibvunit** program converts protocols implemented on physical devices into the communication protocol ibprotocol used by all components of the **IB-System**.

===== Version =====

The documentation applies to the **ibvunit** program in version 2.3.5.

===== Supported physical devices =====

The **ibvunit** program is compatible with all devices equipped with the MODBUS RTU communication protocol. The MODBUS RTU protocol specification is available in a separate document.

Example of physical devices:

  * Output modules with, for example, relay, analog outputs, etc.
  * Measurement/input modules allowing reading of parameters like temperature, humidity, state, etc.
  * Complete devices equipped with a MODBUS RTU communication interface (e.g., heat pumps, fans)
  * Communication interfaces
  * Communication gateways
