After a fast lookup on the controller, Modbus RTU can be used via RS232. Althrough it can have some more advanced limitations towards the controller, for standard usage it should be possible. All modbus registers are stated in the communication documentation. Otherwise, Ive never used that controller so cant really say, but the documentations says its compatible with applications that only use modbus RTU for communicating. This would be the easiest solution if you dont want to code the driver yourself and just download a modbus library for labview 🙂
