*1. Each channel operates on a separate I/O.
*2. The 3-stage are pre-forecast, forecast, and machine stoppage.
Pre-forecast: Displayed only on LCD (no external output is provided).
Forecast: Displayed on LCD and LED and output (output for each counter).
Machine stoppage: Displayed on LCD and LED and output (output when the count value of one or more of counters 1
to 9 has reached its machine stoppage value).
*3. This Counter operates on the forecast value only.
*4. The pre-forecast value is set as a negative offset in respect to the forecast value.
*5. The machine stoppage value is set as a positive offset in respect to the forecast value.
*2. The 3-stage are pre-forecast, forecast, and machine stoppage.
