High-speed Counter

Range Comparison &

Bit Pattern Output

In this example, pulse input 1 operates a high-speed counter, the high-speed counter PV is compared in a range comparison, and corresponding bit pattern is output internally when the PV is within a specified range. The internal bit pattern value is output by a transfer to CIO 0001.

The Reset Bit is kept ON in the program and the counter PV is reset when the phase-Z signal turns ON after the PV reaches its maximum value. Before run- ning the program, make the following settings in the System Setup and restart the FQM1 to enable the new settings.

Counter 1:

Linear counter, Counting speed = 50 kHz, Phase Z and software reset, and Increment/decrement pulse input

The other System Setup settings are left at their default settings.

Example

When the PV is between 0 and 2,500 hex, CIO 0001.00 is ON. When the PV is between 2,501 and 7,500 hex, CIO 0001.01 is ON. When the PV is between 7,501 and 10,000 hex, CIO 0001.02 is ON. When the PV is 10,001 hex or higher, CIO 0001.03 is ON.
