I will suggest you try one of the Data Reader components 'Type 9' you should be able to read your data and use as input for other components, the component also allows you to read the data at specified intervals.
In simulation studio;
1.Under list of components
2. Click Utility groups
3. Select data reader
4. There are 3 different type9 components that you can select from
5. You need to read their description to select which one is more suitable for your application
Can you clear out what is the purpose of having this data in TRNSYS? And what is other software tool? Maybe there is already existing integration (Like it is for ESP-r)
There is variuos ways how to import the data (text table readers like Type9 is one of available options)
Keep in mind that TRNSYS is able to obtain data excel, matlab or other environments. The nice thing that in instalation directory you can find existing example models which could be easily adopter for your case.
