6.4 Changing the Setpoint Using the Setpoint Dialog Box
Any operator whose login account is configured with the appropriate privilege can use the
CN8-SW system to change a controllerÕs setpoint.
To change a controllerÕs setpoint:
1. Access the window used to change the setpoint by:
· r i g h t - c l i c k i n g o n t h e c o n t r o l l e r Õ s i m a g e i n t h e m a i n d i s p l a y ,
o r
· l e f t - c l i c k i n g o n t h e c o n t r o l l e r t o s e l e c t i t , t h e n s e l e c t i n g C o n t r o l l e r |
S e t p o i n t .
Either of these actions will open the Setpoint window.
2. Enter the new setpoint.
3. If you want the setpoint to be written to the controllerÕs non-volatile memory when you
click on Send, click on the box in front of ÒPermanentÓ. The box will be checked.
(Clicking on the box again clears it.) If the controllerÕs power is cycled after you click
on Send, the new SP will be used again when power is restored, because the new
SP will have been stored in the controllerÕs non-volatile memory.
or
If you want the setpoint to be written to temporary (volatile RAM) memory when you
click on Send, do not click on the ÒPermanentÓ box. If the controllerÕs power is
cycled, the new SP will be lost.
4. Click on Send. The new setpoint will be sent to the controller the next time the CN8-
SW computer communicates with the controller.

As with any RS-485 host, the CN8-SW computer communicates with one device at a time. To see
which controller the CN8-SW application is currently communicating with, check the message at the left
of the status bar (at the bottom of the CN8-SW main window). If the status bar is not visible, use the
View menuÕs Status Bar item to display the status bar.
