PID Loop Operation (DL450 only)
DL405 User Manual, 4th Edition, Rev. A
Ramp/Soak
R/S (Ramp/Soak) is the last dialog available in the PID setup. The basic PID does
not require any entries to be made in order to operate the PID loop. Ramp/Soak will
be discussed in another section in this chapter.
Complete the PID Setup
Once you have filled in the necessary information for the basic PID s etup, the
configuration should be saved. The icons on the Setup PID dialog will allow you to
save the configuration to the PLC and to disk. The save to icons have the arrow
pointing to the PLC and disk. The read from icons have the arrows pointing away
from the PLC and disk.
An optional feature is available with the Doc tab in the Setup PID window. You enter a
name and description for the loop. This is useful if there are more than one PID loop
in your application.
NOTE: It is good practice to save your project after setting up the PID loop by
selecting File from the menu toolbar, then Save project > to disk. In addition to
saving your entire project, all the PID parameters are also saved.
