PWM
Note:
The function is available for DIO modules.
The
PWM Configuration
section on
the
PWM
page allows you to 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.
Note:
Because of the characteristics of the relay functions, it is recommended that the
PWM on ET-2260/2261/2268 module (i.e., modules with relay functions) is not used
for extended periods of time.

PWM Configuration
The table describes the parameters contained in the "
PWM Configuration
" section.
Item
Description
Defaults
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.
