Why Daylightingcontrol doesn't work and the DGI could not associate with EMS？

edit

hi everybody，im stuck with this problem. It's about EC window,In the EMS, I set the construction, from the output variables:Surface Window System Solar Transmittanceand,it changes with the glass states. However,the Daylightingcontrols: Daylighting Reference Point Glare Index doesn't change,here is the ouput. Without EMS,if i set Windowshadingcontrol and there are two states of window, the daylightingcontrol can sense the glare and switch the window to dark state. The question is that it seems Daylighting reference point can't work with EMS,don't konw if anybody know how to deal with it or have the same problem,any comments would be really helpful!Thanks! Here is the link and thank you！
