4.5.3 Monitor the Feedback Signal
The feedback signal can be monitored using an A/D card in the PC, or a PLC.
Although, currently available through the RS485 interface, the user may find it
more convenient to directly read the transducer analog output. This would be
beneficial when adding to existing system software which performs system
control, data acquisition, etc.
