SignalGenerator: Function block for the generation of measuring signals (9300 ServoPLC, DrivePLC, ECS)

This Automation Building Block Manual contains detailed information on the user function block SignalGenerator which can provide common test signals via digital and analog output signals for measuring purposes. The following signal types can be generated: square wave signals with an adjustable duty cycle (digital signals = _b signals), sawtooth signals, and sine waves (analog signals = _a signals). For all signal types, you can select the cycle time of a signal period and the maximum value (amplitude) as process values.

Features:

Generation of a digital PWM signal with adjustable duty cycle and adjustable cycle time

Generation of a rising sawtooth signal with adjustable peak (0 ... 100 %) and adjustable cycle time

Generation of a sine signal with adjustable amplitude (0 ... 100 %)  and adjustable cycle time

Applications:

Generation of measuring and reference signals

Control of heaters via a low-frequency PWM signal

Creation of phase-locked loops
