# Product Licensing ## Introduction {% hint style="info" %} All HVAC by powerIO® libraries and the CODESYS runtime license can be run in demo mode for 30 minutes.\ All function blocks and example applications can be tested in full during this time. After 30 minutes, program execution stops.\ Restarting the controller allows demo mode to be run again. {% endhint %} The HVAC by powerIO® libraries must be licensed per controller.\ This licensing option is identified in the [CODESYS Store](https://store.codesys.com/) and in the product names with the suffix *SL* . The abbreviation *SL* stands for *Single license*. > When HVAC by powerIO® libraries are updated, the license remains valid. ## Requirements for using Single License products The HVAC by powerIO® libraries can be used on CODESYS controllers that have a software license container (formerly referred to as SoftContainer) *or* with a CODESYS Key (dongle). Whether the controller supports the software license container and/or the CODESYS Key (dongle) can be checked with a free application from CODESYS on the target device. For this, please use the [Device Reader](https://store.codesys.com/de/device-reader.html), which you can download in the [CODESYS Store](https://store.codesys.com/de/device-reader.html) . For detailed information on licensing, please visit the [CODESYS licensing website](https://de.codesys.com/das-system/lizenzierung.html). Among other things, this provides a decision aid regarding the licensing options CODESYS Key (dongle) and software license container. The CODESYS Key (dongle) can be purchased in the [CODESYS Store](https://store.codesys.com/de/codesys-key.html) . {% hint style="success" %} When purchasing an H1.M100 controller, the CODESYS Key is already included in the package contents and you do not have to buy **a** CODESYS Key (dongle). {% endhint %} From our perspective, the following practical advantages and disadvantages exist between a CODESYS Key (dongle) and a software license container.

	Software license container	CODESYS Key (dongle)
Advantage	Cost-effective, as no additional hardware is required	- Can be used independently of the controller - When replacing the controller, only the CODESYS Key needs to be moved
Disadvantage	- If the controller is defective, the license is lost - When replacing the controller, it must be checked which licenses were previously activated (additional effort)	- Additional costs due to CODESYS Key - Connection to the controller's USB port (must be protected against theft)

### License-required libraries If several libraries requiring the same license are used on one controller, the license is only required once on the controller. It can be used by multiple libraries.

Library	Required license
HVAC Library	HVAC Building Automation Package SL
HVAC Modbus Library	HVAC Building Automation Package SL
HVAC KNX Library	HVAC KNX SL
HVAC BACnet2 Library	HVAC Building Automation Package SL + BACnet SL from CODESYS
HVACFAM Alarm Email Library	HVAC Building Automation Package SL + IIoT Library from CODESYS*¹
HVAC ModbusIO2 Library	License-free
POWERIOHW Library	License-free
HVAC CSV Library	HVAC Building Automation Package SL
MySQL Library	MySQL Library SL

{% hint style="info" %} Optional licenses \ \ ^\*1 For the functionality of sending mail. The library also works without sending mail. The alarms can optionally be sent via the [HVAC Automation Portal](/hub/hvac-automation-portal/en/readme.md) , for which no separate license is required. {% endhint %} ## Purchase license[](https://support.powerio.com/docs-hvac/overview/library-licensing#lizenz-erwerben) The licenses must be purchased via the [CODESYS Store](https://store.codesys.com/de/) . After successful ordering, you will receive a so-called ticket ID for activating and installing the respective license(s). The installation of the license is described in the following section. ## Activate license There are several ways to install a license on the controller. We recommend installing it with the CODESYS License Manager. You can find further ways to install CODESYS licenses on the [CODESYS licensing website](https://de.codesys.com/das-system/lizenzierung.html). {% stepper %} {% step %} ### Open License Manager Open the **License Manager** under *Tools* -> *License Manager*

{% hint style="info" %} **No internet connection? - Alternatives:**\ \ Option 1: \ Create an activation file on a workstation PC with an internet connection and then install it directly. To do this, select **Install license** instead of activate license.\ \ Option 2:\ If a CODESYS Key (dongle) is used, you can also plug it into a workstation PC. Here you can then **Activate license**. {% endhint %} {% endstep %} {% step %} ### Activate license enter the ticket ID to **Activate license** the

If activation was successful, the license will be shown in green in the license view.

{% endstep %} {% endstepper %} ## Move or delete license[](https://support.powerio.com/docs-hvac/overview/library-licensing#lizenz-umziehen-oder-l%C3%B6schen) If a license was installed on the wrong CODESYS Key or software license container, it can be removed with a delete license and activated again.\ \ powerIO® GmbH cannot perform this process. Whether deleting the license and transferring the license is possible must be clarified via the [CODESYS Support](https://de.codesys.com/support-training/codesys-support.html) \n --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
