Advanced PID for precision control
PID (Proportional Integral Derivative) is the most commonly
used feedback control loop in industrial control systems. PID
calculates an error value as the difference between a mea-
sured process variable and a desired set point. The controller
then attempts to minimize the error by adjusting the process
control. With MicroSmart Pentra PLCs, PID implementation
can be deployed in two ways: integrated PID controls or a
dedicated Process Control module, which can be mounted on
the MicroSmart Pentra expansion bus.
Integrated PID Controls
Using built-in PID functions in the MicroSmart Pentra PLCs,
and in conjunction with analog I/O expansion modules, a
maximum of 56 PID loops can be programmed. A PID Macro
instruction in WindLDR software is also available to guide
you through the process of setting up and tuning the P, I and
D parameters. You can also select from various control modes
including Auto-tuning, Advanced Auto-tuning or Manual.
Advanced PID Control Module
A dedicated PID Control module is available for extreme
stability and complex applications. This particular module
has more functionalities than you will find in any other
controller on the market. Independent of CPU scan time, the
PID Control module does the work, reducing PLC scan time
without taking up PLC memory space.
