Counting Functions - PLCS HSC

Disabling to count, sampling counting, latch counting and periodic pulse counting are can be used.

If the following data are written in buffer memory(ch1:1AH ch2:3AH) and starting to count is given (Y06(Y0E) is on by an outer input or a user program), one among the four counting functions can be used.

Counting Function

Set Value

Note

Disabling to Count

0

In case that start to count is on while enabling to count(Y04(Y0c)) is turning on, counting is stopped.

Latch Counting

1

A currently counted value is stored for a certain time.

Sampling Counting

2

The pulses inputted during a set time are counted.

Periodic Pulse Counting

3

A currently and a previously counted value are stored for set periodic time.

Point

Counting functions can be changed while starting to count is off.

If the value in the range from 1 to 65535 is inputted to buffer memory(ch1:1B , ch2:3B), set sampling/periodic time can be changed.
The unit is 10ms. If 10 are inputted, it will be 10*10ms = 100ms.
