This simple logic group puts two values into one (text) telegram.

This makes it possible, for example, to display the minimum and maximum daily temperature values as text (e.g. "21°C/13°C") on a KNX push button sensor.

The two temperature values are first rounded to one decimal place and placed in a text with the LUA script element. The rounding is done because of the limited text length (14 characters). The values are separated from each other with a "/". This composite text is then sent on the KNX bus.

Note: For this example, the data point type DPST 16.001 (ISO 8859-1) is to be used, as this uses an 8-bit character set and thus also allows various special characters.
