Re: [EnergyPlus_Support] EMS callin point for Output:Variable (include meters)





the variables are reported in "real time". you need to adjust your report for "daylight savings time" perhaps?

to test, run the same code in winter. there we are in real time and there should be no shift.

Hi group.


I'm having problems creating a custom variable through EMS module.


My program is very simple, just make an unit conversion for a METER. And I remark it with caps because I thinks this is the problem.


For a variable from the RDD list, there is no problem. I use â??End of Zone Timestep Before Reportingâ?? calling point, and no problem is showed.


But the problem appears when the program includes the use of a meter. I'm using a sensor which reads "InteriorLights:Electricity" meter. Then the program just converts J to kWh.


When I review the results file (I ask for the EMS variable and the meter), the EMS variable mismatches by one forward timestep:


TIMESTEP    EMS VARIABLE    METER

 01/01  06:05:00 0 5402563.63
 01/01  06:10:00 1.50071212 5402563.63

[...]

 01/01  10:00:00 1.50071212 5402563.63
 01/01  10:05:00 1.50071212 0


I tried with other calling point â??End of Zone Timestep After Reportingâ??, thinking if meters are calculater just for the reporting but the results are the same.


Have you already faced this problem? Am I doing something wrong?


Thanks in advance.
