8.3.4.5 F178_HighSpeedCounter_Measure, Input Pulse Measurement

This instruction measures the number of input pulses in a specified counting period and the
pulse period.
Characteristics of input pulse measurement

For input pulse measurement, the channel number, the counting period (1ms–5s) and
the number of counting periods (1–5) must be specified. These parameters are used
to calculate the average number of input pulses per counting period.

The unit of pulse period measurement ([s], [ms] or both) can be specified.
REFERENCE
Please refer to the FPWIN Pro online help for details and a programming
example.

8.3.5 Sample Programs

The following programming examples demonstrate how to make control code settings and
how to use the high-speed counter instructions.
The FPWIN Pro projects in LD and ST code can be downloaded from the Panasonic Web site
(http://www.panasonic-electric-works.com/peweu/en/html/22164.php).
The programming examples for this chapter can be found in
pe_63403_0001_sample_high_speed.zip.
These examples can be used with different PLC types. Therefore you have to adapt the PLC
type in the Control FPWIN Pro Navigator.
After you have changed the PLC type, a message appears: "Adapt System Registers and
Compile Options?" Select [Adapt automatically], so that you do not lose the system register
settings set in the programming example.
