EZ I/O
EZI/O System supports two High Speed 24 bit Counter
Modules with PLS outputs that accept quadrature encoder
inputs. The PLS outputs compare the counter value to two
on/off presets and turn on outputs within 100µs of position
change. Presets can be loaded into the counter modules
from EZPLC. All inputs and outputs are optically isolated.
In addition, PLS outputs are 0.5A short circuit proof DC
outputs.
The counters have various preset/reset and inhibit modes as
shown on the following page.

1. This mode will preset the counter to the preset value while
preset is held high. While the preset signal is high, no new
count signals will be counted.
2. This mode will create an interrupt on the rising edge of the
reset signal to set the counter to the preset value.
3. This mode will create an interrupt on the falling edge of the
preset signal to set the counter to the preset value.
4. This mode will create a preset pulse every time that there is a
rising edge of signal A and the preset signal is high.
