We have developed C#/WPF application that gets thermocouple data from various hardware, creates charts/reports and manages various project related tasks. In the past we have communicated NI Compact FieldPoint devices by using OPC DA. I was very satisfied with cFP devices and its OPC DA support and easy configuration options. We did not need LabView at all. Now cFP is outdated and we still want to support NI devices.
1. What is your suggestion for cFP replacement? Is it CompactRIO?
2. What are the best options to get data by means of our own application? Can we still use OPC DA like cFP? Any SDK?
3. Is LabView license required? Do I need to install LabView?
Thank you in advance.
