Counter settings

To enable correct calculation of delta values it is important to specify the low value of the counter and the high (roll-over) value.

The low value is typically 0, whilst the high value is typically the size of the data type.

Caution: 
It is essential that you enter the correct high value, otherwise you will get the wrong delta value on roll-over.

These additional enable the OPC value to be manipulated before the delta calculation is performed:

  • Offset: To offset the raw value by a specific number.
  • Multiplier: To multiply the raw value by a consistent amount. For example, if 1 count means 2 pieces have been produced by the machine.
