Process control of semi-continuous processes
The CCX 17 industrial operator panel displays and controls all the PID controller
parameters which can be modified without having to program the Micro or
Premium PLC application program.
The PID_MMI man-machine interface function, included in the PL7 Junior software,
provides an application program on the CCX 17 industrial operator panel for
controlling and adjusting PID loops.
It enables the CCX 17 operator panel to manage:
b Selection of a PID loop.
b Display and control of that PID loop.
b Adjustment of the PID loop parameters.
This man-machine interface function is easily installed for any man-machine
interface application on the CCX 17 operator panel. The three preconfigured screens
enable the required operations to be performed on any PID controller.
The CCX 17 operator panel can manage up to 9 PID controllers. Installation of the
man-machine interface function is simple and is performed as follows:
b The PID_MMI function is activated on each scan of the TSX Micro or Premium
PLC (unconditional call-up).
b A single call-up of the PID_MMI function manages all the PID loops in the
TSX Micro or Premium PLC -application.
