6–8 Tuning the Loops
Publication 1771Ć6.4.5 - January 1997
You can change the system response setting after auto-tuning is
complete, provided you follow these steps:
1. At the Tuning Results screen, select the loop you wish to alter.
2. From the
Loop menu, select Configure tuning.
Accessing the tuning configuration values
To access the configuration values for this loop, you can also double
click on the loop.
The Tuning Configuration screen appears.
3. Change the system response setting.
4. Download to the PLC processor.
5. At the Tuning Results screen, download the system dynamics
values for the loop.
This triggers the module to recalculate new proportional, integral,
and derivative gains based on the system dynamics and the new
system response setting.
To learn how to monitor and control the loops, read chapter 7.
