Count up by 1 eyery time for a cycle

[AmeHyesung]

Hello everyone we are now using labview for our project, which is to manage charging and discharging process for a battery. And we need to record the life cycle for the battery. That is when recharging it life cycle should be increased by 1.

We try to use case structure with for loop but it increase too fast and keep increasing. I only want it to increase once when limitation is meeted. Also I try to use shift register but it can't stop...also keep increasing unless I  stop the whole program.

Can anyone help us with this problem?? If recieve a signal, boolean or something else..., life cycle(variable) will increase by 1.

Millions of thakls!!!

You should be able to use the loop counter from your outer most For or While Loop to count up a number for each cycle, assuming that you have each charge and discharge as a single process. 

Otherwise you should be able to implement the counter pretty simply dependent on some condition using the most basic set up of:

here's a simulation using a state machine, see if you understand the process here. user sets charge and discharge capacity and the number of cycles to be done.

This all seems to be working fine, Is there anything else that you need help with?

Thanks !!! I'll try it!!!

really really thank you!!!!!!!

Hello apok~I try to connet the vi that you did with a DAQ to get the state of charge from a battery. But when connect to daq the program cannot work well....When press start putton there's nothing happen.  mAh also doesn't indicate SOC and it won't change to either 'charge' or 'discharge'... Is there something wrong with what I added??

Hi Ame,

are you working with hahaxuan on the same project?

yes...dataflow. the daq must be read by the loop, whether it's internal(daq in same loop) or a second loop communicating through queues or locals and not by the way you connected the 2 loops.

hmmm...i've read the SOC somewhere? are you working with @JoeR_87 

[AmeHyesung]

Sorry...what do you mean by locals??? local variables or a function??

 I'm not working with  him~ 🙂
