Standard beginning

The function block fbStandardBegin determines the start conditions for the step sequence and monitors the safe status to allow automatic or manual operation. This function block is a main component of every sequence and is located in the Selmo Basic library. refHwzHmi is the reference (pointer) to the variable list "GVL_<HwZone_name>_HMI.stHmiIf" refHwzIf is the reference (pointer) to the variable list "GVL_<HwZone_name>.stHwzIf" refSeqHmi is the reference (pointer) to the variable list "GVL_<Sequence_name>_HMI.stHmiIf" (stHmiSequence) refSeqIf is the reference (pointer) to the variable list "GVL_<Sequence_name>.stSeqIf" (stSequenceInterface) xSeqSafetyModeOn Query of the safety key switch "GVL_<HwZone_name>_IOs.xSafetyFunctionKeySwitch" iSeqStepcounter current step counter of the sequence "GVL_<Sequence_name>.iStepcounter" aSeqPb Array of manual operation push buttons (HMI Buttons) is increased by one index per active HMI button per zone aLampMatrix Array of the bit matrix (variable declaration) is increased by two indices per zone aStepMatrix Array of the bit matrix (variable declaration) is increased by two indices per zone aTempMatrix Array of the bit matrix (variable declaration) is increased by two indices per zone aEocSteps Array of the bit matrix (Variable declaration) is increased by one index per step
