EGX300 with firmware 4.450 not plotting demand properly
Issue
EGX300 with firmware 4.450 does not plot demand properly on the gateway site. It shows demand as negative values at times.
Product Line
EGX300
Environment
EGX site
EGX disk image
Cause
The EGX300 is incorrectly calculating demand as cumulative data i.e. it tries to calculate interval data by subtracting the last data record with the current data record. This incorrect calculation causes some demand values to drop to negative numbers if the previous interval's demand is higher than the current one.
