Firmware Update

5.5.1

Firmware Update using the Website of the Device

The ise smart connect Modbus Vaillant provides a way to install a firmware update via the device web-
site. To do this, please choose Firmware update from the menu on the device website. The ise smart
connect Modbus Vaillant will automatically check for a new version with our update server. The update
page will display the current version as well as the version of an update if available. If an update can be
installed, a brief description of the update is provided.
If the new firmware is not compatible with the old unit ID and/or register layout, a corresponding mes-
sage is displayed. Between following cases can be distinguished:
1. The new version provides new functionality. The device will work with the same functionality af-
ter the update. However, to use any new functionality, a reconfiguration of the Modbus TCP/IP
client (which is in general part of the BMS) and/or a factory reset is required.
2. The new version has a unit ID and/or register layout which is completely incompatible with the
layout of the currently used version. A reconfiguration of the Modbus TCP/IP client (which is in
general part of the BMS) is mandatory. If a factory reset of the device is necessary, there will be
a hint in the message.
The update can be started with the button Perform update. In case of an incompatibility, the start of the
update has to be confirmed once more.
5.5.2

Local Update without Internet Access

In addition to the online update, a local update without need of an active internet connection can be
used. This is intended for devices, which are only accessible over the local area network. The firmware
file can be selected locally using the Select file button and then started using the Update firmware but-
ton. In this case, the user is responsible to assure that the update is compatible (see chapter 5.5.3
"Firmware Version Numbers"). A downgrade to an older version is not possible.
5.5.3

Firmware Version Numbers

The version number of the firmware is structured according to the pattern X.Y. The major number X of
the corresponding version specifies the compatibility. If the major number of a new firmware is equal to
the current firmware, the unit ID and/or register layout is fully compatible. The second part Y of the ver-
sion number is not relevant to compatibility issues. It signals only an update within the version.
If the major number of a new firmware is higher, it is not guaranteed that this version is compatible with
the unit ID and/or register layout. Therefore, it is recommended to check the configuration of the Mod-
bus TCP/IP client.
If the major numbers are equal, it may be necessary to reconfigure the Modbus TCP/IP client and/or
perform a factory reset to have access to all features. This is not mandatory in case the new functions
are not used.
