SCL - Scale Data

Use this instruction to scale data from your analog module and bring it into the limits prescribed by the process variable or another analog module. When rung conditions are true, this instruction multiplies the source by a specified rate. The rounded result is added to an offset value and placed in the destination.

Example

Equation: N7:111 = (N110 * 100/10000) + 10

Note

  • If the result of the source value / 10000 > 32767 this will generate a minor error fault. This error should be cleared to avoid a major error.
