The following table lists the STS properties you can access from this step. Except for the TestHeadAvailable property, these queries must be run only on an STS with STS Maintenance Software 19.0 or later.
NameTypeDescription
12VPowerSupplyEnabledBooleanReturns whether the 12 V pins on STS CX and STS DX systems are enabled. The pins are disabled by default at STS power up and when a load board is not installed or locked down on the STS, such as when the value of the DIBPresent property is False. These signals are available on the system cable for STS CX systems and on the P143 system block for STS DX systems.
Note You can successfully make this query only on STS M2 systems. Otherwise, the step returns a run-time error.
48VPowerSupplyEnabledBooleanReturns whether the 48 V pins on STS CX and STS DX systems are enabled. The pins are disabled by default at STS power up and when a load board is not installed or locked down on the STS, such as when the value of the DIBPresent property is False. These signals are available on the system cable for STS CX systems and on the P143 system block for STS DX systems.
Note The step returns a run-time error if you make this query on STS T1 M1 systems.
CurrentRunTimeStringReads from the system controller of the STS the amount of time the STS has been running since the last power-on event.
DIBLockedBooleanReturns the locked state of the DIB locker.
DIBPresentBooleanReturns whether a load board is installed by detecting whether the load board shorts the DIB_INTERLOCK pin to GND. The DIB_INTERLOCK and GND signals are available on the system cable for STS CX systems and on the P143 system block for STS DX systems.
Note You must design the load board to connect DIB_INTERLOCK to GND to activate STS DIB detection. Refer to the DIB Design Kit for more information about designing load boards.
FramePartNumberStringReturns the unique identifier and revision of the STS.
FrameSerialNumberStringReturns the unique serial number of the STS.
LoadBoardIDPROM.ChecksumPassedBooleanReturns whether the checksum of the load board passed.
LoadBoardIDPROM.DateManufacturedStringReturns the manufacture date of the load board.
LoadBoardIDPROM.DescriptionStringReturns the description of the load board.
LoadBoardIDPROM.FormatNumberReturns the version number of the format that describes how the raw data from the IDPROM is converted into IDPROM values.
LoadBoardIDPROM.ManufacturerStringReturns the manufacturer of the load board.
LoadBoardIDPROM.PartNumberStringReturns the part number of the load board. By default, TSM writes this property to the LoadBoardTypestation settings and logs the value to the corresponding STDF record field if LoadBoardIDPROM.ChecksumPassed is true. You can override this behavior in the GetStationSettings and ConfigureStationSettings callback sequences of the SemiconductorModuleCallbacks.seq sequence file.
LoadBoardIDPROM.RevisionNumberReturns the revision number of the load board.
LoadBoardIDPROM.SerialNumberNumberReturns the serial number of the load board. By default, TSM writes this property to the LoadBoardIdstation settings and logs the value to the corresponding STDF record field if LoadBoardIDPROM.ChecksumPassed is true. You can override this behavior in the GetStationSettings and ConfigureStationSettings callback sequences of the SemiconductorModuleCallbacks.seq sequence file.
SystemPartNumberStringReturns the unique identifier and revision of the STS configuration.
SystemSerialNumberStringReturns the unique serial number of the STS configuration.
Note If the STS does not return a serial number or the serial number is “NOTSET”, this property returns the same value as the FrameSerialNumber property.
TestHeadAvailableBooleanReturns whether TSM can access the STS. The following conditions prevent TSM from accessing the STS:
  • STS Maintenance Software is not installed.
  • The version of STS Maintenance Software is earlier than version 19.0.
  • An error occurred when trying to communicate with the STS.
TotalRunTimeStringReads from the system controller of the STS the amount of time the STS has run over its entire lifetime.
