Hi

I am currently trying to set up a program with counter inputs from an energy meter. I have setup the inputs fine and also used +CV command to accumulate the kWh.

What i want to do now is to setup another schedule to calculate the daily kWh reading whereby I read the counter input every second and add this to a +cv and run another schedule at 1 day interval to give the one daily reading.

However if i reset the counter input in one schedule the other schedule does not see the counts. here is a copy of the program created with delogger 5 DT85 series 3.

can you advise how i might program this so i can record accumulated kWh and also a daily kWh.

thank you
Stephen

Good afternoon Stephen,

In schedule A you are sampling counters 3 and 4 every 15 minutes and then resetting the counters.
3C(R,"M1",W,+=1CV)
4C(R,"M2",W,+=2CV)

In schedule B you are sampling counters 3 and 4 every 1 second and then resetting the counters.
3C(R,"M1-1sec",W,+=5CV)
4C(R,"M2-1sec",W,+=6CV)

I would re-arrange the schedule swapping schedule A with B so the one second schedule runs first
Leave the code for the counters as is
3C(R,"M1-1sec",W,+=1CV)
4C(R,"M2-2sec",W,+=2CV)

Then in the 15 minute schedule report and reset the CV values
1CV(R,"M1-1sec",W,+=5CV)
2CV(R,"M2-1sec",W,+=6CV)

This way you only reset the counter once.

Cheers,
Roger

Hi Roger,
Thank you for your reply. below is the changes i have made to the program as suggested, can you please confirm i have carried this out correctly to acheieve the accumulated Kwh and the daily Kwh.

RS1S

RB("B:",ALARMS:OV:100KB,DATA:OV:20MB)15M LOGONB GB
3C(R,"M1",W,+=1CV)
4C(R,"M2",W,+=2CV)

5CV(S4,"EM01 Daily",R)
6CV(S4,"EM02 Daily",R)

finally the logon command is given via an alarm between hours of the day, with this trigger and schedule C only logging once per day will Schedule C once per day still take a log if the alarm has run a logoff command at 20:00.

Thank you.
Stephen

Hi Stephen,

Not quite. You are still resetting the counters at two point rather than one.

More like:
'schedule definition
RA("B:",ALARMS:OV:100KB,DATA:OV:2MB)1S LOGONA GA
3C(R,"M1-1sec",W,+=1CV)
4C(R,"M2-1sec",W,+=2CV)

RB("B:",ALARMS:OV:100KB,DATA:OV:20MB)15M LOGONB GB
1CV(R,S4,"EM01",W,+=5CV)
2CV(R,S4,"EM02",W,+=6CV)

RC"PVDaily"("B:",ALARMS:OV:100KB,DATA:OV:5MB)1D LOGONC GC
5CV(S4,"EM01 Daily",R)
6CV(S4,"EM02 Daily",R)
