Excel VBA change value

Hi, I have an application with a Delta RMC150. In this application, a PLC send command to RMC. I want to have VBA application who show Preset value in the RMC and i want to change this preset value from VBA.

I know it’s possible to read data from RMC with VBA but is it possible to write data?

Tanks for your help

Yes, it is possible to write to the RMC. Use the WriteFFile method to write floating point data, or the Write Files method to write integers.
The RMCLink installer will install examples, and those examples for VBA do show how to write.
