Lot Start begins at sbSECSLotStartClick or an OLP LotInfo_REQUEST, then calls SetLotStart which writes the Lot ID and start time to config.ini, clears by-lot statistics, fires the DoLotStart SECS event, and locks the UI. The full state machine is defined around line 1438 of uLotInfo.cpp.

Recipe download runs through DownloadFromServer, which validates the RMS connection, backs up local parameters via DoBackupSetupFile, unzips the package with 7z.exe, verifies eight required data files, then restores protected local settings via DoOverWriteSetupFile.

Contact Height is overwritten when the Security_new.def [Network] Contact High flag is true, meaning server values are accepted. The default is false, which preserves local Contact Height during DoOverWriteSetupFile; Greatek builds force all flags to true.

DoLotStart fires inside SetLotStart only when the customer is not TSMC Tainan, SECS/GEM is enabled, and RunInfo.bLotStart is false, preventing duplicate events. In 2DID sorting mode, DoVisualSortLotStart is sent instead.

sbSECSLotEndClick rejects Lot End when SystemStart is true, CheckCanChangeRealDummy fails, or iTestHeadMotorTask equals 1, meaning the index is currently pressing down. These guards prevent ending a lot during active machine operation.

All Lot Info fields persist to config.ini under the [Lot Info] section at AuthPath, including Lot ID, LotStartTime, OP ID, Run Mode, and Station. On FormShow, SetLotStart runs in restore mode with bReadFromFile=true to reload these values.
