Explain the parameters of the Scale (SCL) instruction.
What will be an ideal response?
Source—A word address containing the value to be scaled. Example: integer word N7:0, analog input word I:1.0, etc.
Rate—The slope (rate) can be a program constant or a word address. Most often this is a program constant that you have calculated. The rate value you enter, either positive or negative, is divided by 10,000 prior to being applied to the source. The rate value is limited to a range of -32,768/10,000 to 32,767/10,000 or more correctly a rate of -3.2768 to 3.2767. For example, if your calculated slope (rate) is 1.5, then enter 15,000 into the Rate parameter.
Offset—The offset can be a program constant or a word address. Like the rate, this is also most often a program constant that you have calculated. Valid range for the offset is-32,768 to 32,767.
Destination—A word address that the scaled value will be placed in. Example: integer word N7:1, analog output word O:2.0, etc.
All parameters, including the Source and Destination, are limited in value to an integer range between -32,768 to 32,767.
