Servo Rate 

Name 

Description 

100 Hz 

PWM signal has constant 100 Hertz frequency (10 msec repetition 

rate) with 0 – 100 % duty cycle

 

50 Hz 

PWM signal has constant 50 Hertz frequency (20 msec repetition 

rate) with 0 – 100 % duty cycle 

6.6.2

 

    Output Type 

Smart Sensor probes support NULL (0), ON/OFF (1), PWM (2) and SERVO (3) outputs. When set to NULL the 

output signal will be left in a high impedance state. When set to ON/OFF the Rate and Servo Range controls 

have no effect. When the SERVO type is selected the Duty-Cycle is restricted so the output signal is either  

0.5 – 2.5 msec or 1.0 to 2.0 msec based on the Servo Range bit. 

6.6.3

 

    Active State 

Smart Sensor discrete outputs may be configured as Active HIGH or Active LOW. When set to 1 (Active High), 

the output will be high impedance when active. When set to 0 (Active Low), the output will be low 

impedance (~ 0.0 volts) when active. The Factory reset value is 0 (Low). 

6.6.4

 

    Mapping Enabled 

The read-only Mapping Enabled bit indicates that the output may be optionally directly mapped to a sensor 

input based on the Sensor Mapping field. If the Mapping Enabled bit is clear no mapping is supported, and 

the Sensor Mapping field is ignored. 

6.6.5

 

    Sensor Mapping 

The Sensor Mapping value may select ‘no mapping’ or any of Sensor 0..3. If no mapping is selected the 

output may be directly controlled by writing a value from 0 – 100 % to the internal Output Value. If a Sensor 

is selected and the hardware supports the mapping the output will track the selected sensor value, scaled by 

the Input Minimum and Input Maximum values. 

If Sensor Mapping is enabled for PWM outputs the scaling values are used such that a signal input at or 

below the Scaling Low-value results in a 0% output and a signal input at or above the Scaling High-value 

results in a 100% PWM duty cycle. 

If Sensor Mapping is enabled for SERVO outputs the scaling values are used such that a signal input at or 

below the Scaling Low-value results in a minimum (0.5 or 1.0 msec) pulse width and a signal input at or 

above the Scaling High-value results in a maximum (2.0 or 2.5 msec) pulse width.
