Counter and Hour counter questions

Hi,

I want to monitor a state of motor and store retentive:

1. Num activation total
2. Num activation today
3. Num activation yesterday
4. Hour activation totale
5. Hour activation today
6. Hour activation yesterday

About point 1 to 5 there are no problem (see attachment) but I dont understand how store the Hour activation yesterday.

Is it possibile?

Another question about Hour counter:

• Is it correct that period < 1 minutes are not considered at all?
• For example if the motor starts 10 times for 50 seconds each the hour counter remain to zero...

Thansk and Best Regards

Yes that's right:

LSC's own operating hours counter only counts elapsed minutes.

If the runtime is less than 1 minute, it is not counted.

With a running time of 2 minutes and 59 seconds, 2 are counted.

The running time from the previous day can be saved by means of an arithmetic instruction, or with the MAX / MIN block, if it has to be voltage fail-safe.

 Hi ixo65,

thanks for clarification about hour timers.

About saving previous day value of counter (num of activation) I have already done (see attachment to my first post) but I dont understand how is possibile to use the same logic (arithmetic instruction, or with the MAX / MIN block) with hour counter.

Can you help me?

Thanks and Best Regards

Yes, the Hourcounter counts only hole minutes.

If its a problem use one of this counters. The first counts hole seconds, and if that not enough, the second counter counts 0,1 sec.
