Mixed Module, 24 V DC Positive Logic Input 20 Points / Output 12 Point /
(4) High-speed Counter, PWM, or Pulse Train Configurable Points
Outputs
Four of the module's twelve outputs are high speed outputs. These outputs can
be configured as high speed counter, PWM, or pulse train outputs.
Counter Outputs
Each counter output has a preset on and off point that must lie between the
counter's high and low limits. The output state indicates when the Accumulator
value is between the Preset on and off points. For example, using the Type B
counter:
If the output is enabled for the HSC channel being used, the output turns on as
displayed in the following table:
Preset closest to
low limit
ON
OFF
The output can be either on or off when the Accumulator value lies between the
Preset points.
