Special Hardware Requirements:
CPU 214 or higher (with analog potentiometer), small screwdriver
CPU 214 or higher (with analog potentiometer), small screwdriver
This example demonstrates how to use the two analog adjustments (potentiometers, or POTs) of the SIMATIC S7-200 CPU. The positions of the potentiometers are converted into digital values between 0 and 255. The value for analog adjustment 0 is stored in special memory byte SMB28; the value for analog adjustment 1 is stored in special memory byte SMB29.
A small screwdriver is required to adjust the positioning.
This application tip demonstrates three ways to use an analog potentiometer to adjust the Preset Time (PT) of a timer.
