Application Notes

The Data type parameter must be one of:

  • Byte

  • UShort, (unsigned integer)

  • Short,(signed integers)

  • Long

  • Float, (real numbers)

  • Double (default setting)

  • String (characters)

The Display width parameter will set the channel width only when the data type selected is String.

The Digits to display parameter controls the total number of digits display (both right and left of decimal point combined). If the value is greater than the DISPWIDTH value, then data in the channel is displayed as a '**' since it cannot totally fit in the width of the display.

The Number of array elements parameter will set the channel array size. The default is 1, i.e. non-array channel.

  • When a new channel is created it will appear to contain dummy values even though it contains no data.
