Today: Brute Force Method
• Power & Signal Delivered to Sensor from ControllerController serve as the I/O DeviceSampling System does not have any “Smarts”All Diagnostics in the Controller

Each sensor uses individual signal/power wiresRequires Wiring HarnessUseful for Remote Operation of Sampling System
(such as NIR and RAMAN analyzers - would be a fiber-optic probe in this case)

Connected to Level 2 Ethernet Field LAN
This configuration would be especially useful where Controller/Analyzer is remotely located from Sampling system (analyzer sensor in this case would typically be a fiber optic probe (e.g., RAMAN and NIR applications)
