Chapter 16: PC Function

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-S30. Then it outputs the results of the calculations performed by the circuit.
Use of the PC function enables the IV-S30 to output measurement results to an external equipment such
as a lamp by itself, without the need for an external PC.

16-1 Operation cycle

The operation cycle of the IV-S30 is outlined below. This flowchart contains only the operations related
to the PC function, and does not show communications with external devices.
