How to get string from Mitsubishi Q series PLC?

We use Kepware to collect data from Mitsubishi Q-series PLCs and process it in ThingWorx.
I'm trying to set the device using the Mitsutubishi Ethernet driver and get the data from the PLC's data register as a string, but I can't select "String" from the data type in the Kepware property editor.
An integer can be obtained by selecting the "Word" data type.
Is there a way to get the string using Kepware?

Or do I have to create a service that takes an integer in Kepware , converts the integer to ASCII code and generate strings in ThingWorx?

Thanks
