S71200 HSC Pulse/Sec to Pulses/Hr
S71200 HSC Pulse/Sec to Pulses/Hr
(OP)
Hello,
can anyone tell me if it possible to infer an intermediate speed measurement from a frequency measurement in pulses per second.
i.e. I have a HSC that counts in Hz such as 15Hz......16Hz.......17Hz.......18Hz.....etc
I would like to be able to get intermediate measurements such as
15.3Hz.....16.25Hz......17.8Hz......18.6Hz......etc
is this possible to do this with a High Speed Counter. I have the HSC configured on a Siemens S71200 PLC
regards

RE: S71200 HSC Pulse/Sec to Pulses/Hr
if you program for the rising and falling edge of the signal you could get double the input hz.
If you go the opposite in time then your just a straight conversion by counting the pulses for per hour.

But if i configure for a pulse for every falling and rising edge am i not miss interrupting a pulse? is that the "A&B Quadrature"? i hear this term before?
I don't understand what you mean when you say
"If you go the opposite in time then your just a straight conversion by counting the pulses for per hour."
Well what i mean by pulses per sec to pulses per hour is that i have a HSC measuring pulses per second and am converting this figure to pulses per hour by multiplying the per/sec value by 3600. the problem is that a jump from for example 15 pulses per sec to 16 pulses per sec causes an increment of 3600 (as expected). I would like there to be a possibility of reducing this large step increase by being able to count for example 15.45 pulse/sec X 3600

I thought a HSC would measure frequency with intermediate values such as 15.3.....15.5....15.9Hz....etc?
