Scaling Data in Ladder Logic

Introduction to Scaling Data in Ladder Logic with ControlLogix In this section, we’ll be Scaling Data in Ladder Logic. Scaling simply means that we convert a raw value into engineering units. For example, 4-10mA of input will give us a raw value of 3277 to 16383. This number does not Read More »
