Communication
INTUNE can communicate via DDE (dynamic
data exchange) or OPC (OLE for Process
Control) to any control system which includes a
DDE or OPC server.
INTUNE also supports direct communication
drivers (developed by ControlSoft) to AllenBradley, Modicon and Siemens-TI family of
PLC’s.

Auto Tuning
PID Auto Tuning
. . . involves conducting a step tuning test on your PID loops
in either open-loop or closed-loop mode.
Auto-tuning tests can be completely automated to trigger on
a click of a button or run in a semi-automated mode.
INTUNE collects process data, analyzes and identifies a
model representing the true process dynamics.

The optimum PID values are
generated based on user
defined tuning priorities.
Upon completion of a test, the
software opens a separate
analysis window presenting the
results.
