Using TOT block to calculate Energy in kWh from Power in KW

[Ihtisham]

I want to calculate the energy consumed from instantaneous power. Can this be done using the TOT block with timebase set to Hour?

Probably. The biggest problem is probably going to limited accuracy due to the precision of the REAL input. Perhaps TOT can take an LREAL input?

Did you read the description of the TOT instruction here?

Is this related to the other thread here?

I suspect you won't be happy with a time base of one hour. There will be lots of power variations in that time frame. Instead, consider using a minute time base and divide the results by 60 to get kWh.
