4.6 PWM
Clicking the
PWM tab will display the PWM Configuration page allowing you enable and configure
the PWM parameters for the ET-2200 series module, including the PWM Alarm and duty cycle, etc.,
each of which will be described in more detail below.
PWM Configuration
The following table provides an overview of the parameters contained in the PWM Configuration
section:
Item Description
Default
Value
Enable PWM This parameter is used to enable the PWM output function. 0
Enable PWM Alarm
This parameter is used to enable the PWM output alarm function when
Host/Slave watchdog timeout.
0
Duty Cycle
This parameter is used to set the duty cycle for the DO channels. Two
values are required for each DO channel.
The first value is the high pulse width, while the second is the low pulse
width. The duty cycle is in 1 ms units, and the resolution is
approximately 5 ms. (10 to 65535 ms). A value of 0 will disable the duty
cycle functions for that channel.
1000
(ms)
Update Settings Click this button to save the revised settings to the ET-2200 module.
Note: Because of the characteristics of the relay functions, it is recommended that the PWM on
ET-2260/2261/2268module (i.e., modules with relay functions) is not used for extended periods of
time.
