I have a Modbus module from ICPDAS (ET-7019/PET-7019), which I want to read data directly from. Since I'm fairly new to Modbus, not really sure where to start from. I have read the Modbus introduction and understood some of the basics. I've also downloaded the Modbus library but don't really see any good example. The ICPDAS Modbus module is ethernet based and is currently connected to our network. The ICPDAS can log data but I'd like to read data directly using LabVIEW.
We have LabVIEW 2009 development suite and RT module, cFP 2220 and 180x. I read some sections saying using cRIO as modbus master/slaves and assume we can use cFP as a similar method? I don't have DSC module.
Would someone be nice to draw a diagram or explain where I can start in terms of connection and configuration? Read from ICPDAS is the only function I need.
Many thanks,
Dahai
