Trim Pots Trim Pot Operation
The MicroLogix 1400 controller provides two trimming potentiometers (trim
pots, POT0 and POT1) which allow modification of integer data within the
controller. The data value of each trim pot can be used throughout the control
program for timers, counters, analog presets, depending upon the
requirements of the application.
You can change the data value of each trim pot using the trim pot screens
provided by the LCD. To access to the Trim Pot Set screen, which is the top
screen for the trim pot functionality, select TrimPot Set on the LCD default
menu screen, as shown below, and press OK on the LCD keypad.
Trim pot data is updated continuously whenever the controller is powered-up.
