Cal time in ION diagnostic module

[Liangchen1982]

Hello SE experts,

We have many sites using ION8650 dynamic programming: meters talk to each other through modbus master/slave modules, the master meter poll resource meters data, and doing loss allocation calculation,  then sending back the results to the resource meters. And we are experiencing energy spike data in the load profile which could because of the communication delay and high CPU usage.

I am checking the meter's diagnostic module, Calc time is "6590". what does this mean? ION reference doesn't have explanation. Could you pls help clarify it?

Hello @Liangchen1982 ,

The Calc time is the execution duration (in micro-seconds) of a portion of the meter's internal one-second calculations that does not include the one-second framework and some other calculations.
