Chapter 15: PC Function

15-1 Outline

The PC function is designed to create a ladder circuit program based on the data (coordinates,
distance, degree of match, and results of numerical calculations) obtained from the measurements
and calculations made by the IV-S30J. Then it outputs the results of the calculations performed by the
circuit.
Use of the PC function enables the IV-S30J to output measurement results to an external equipment
such as a lamp by itself, without the need for an external PC.

15-2 Operation cycle

The operation cycle of the IV-S30J is outlined below. This flowchart contains only the operations
related to the PC function, and does not show communications with external devices.
