Variable name
Description
Compact Errors
This is a compact version of the "Errors" result variable It may list the following errors:
 THM -Torque High Monitoring (bit 0, value 1)
 TLM -Torque Low Monitoring (bit 1, value 2)
 AHM -Angle High Monitoring (bit 2, value 4)
 ALM -Angle Low Monitoring (bit 3, value 8)
 OK – Bolt status is OK (bit 4, value 16). This bit is set if the bolts final status is OK. It
means that there where no errors at all.
When reported binary, each error is represented by the bit written within parentheses
above (bit 0 is the least significant).
Failing Step No
The number of the last step that failed in the main part of a program. Only valid if bolt
status is NOK, or TERMNOK.
Pgm No
The optional number assigned to the program that was used to tighten the bolt. Set using
The Tightening Program form.
Ordinal No
Ordinal Bolt Number. This is always an enumeration of the bolt‟s position within the
station.
Bolt A Thresh T
The threshold torque level Tstart for measuring of Bolt A.
Spindle Serial No
The serial number of the spindle that tightened the bolt.
Compact Errors 2
This is a compact version of the "Errors" result variable It may list the following errors:
 TLM -Torque Low Monitoring (bit 0, value 1)
 THM -Torque High Monitoring (bit 1, value 2)
 ALM -Angle Low Monitoring (bit 2, value 4)
 AHM -Angle High Monitoring (bit 3, value 8)
 TR1LM - Torque rate in interval 1 too low during monitoring (bit 4, value 16).
 TR1HM - Torque rate in interval 1 too high during monitoring (bit 5, value 32).
 TR2LM - Torque rate in interval 2 too low during monitoring (bit 6, value 64).
 TR2HM - Torque rate in interval 2 too high during monitoring (bit 7, value 128).
When reported binary, each error is represented by the bit written within parentheses
above (bit 0 is the least significant).
Bolt Pgm Time
The time when the program was last changed or setup downloaded to TC.
Bolt Pgm Strategy
The control strategy of the program. This value is set according to the strategy type of the
last step in the program according to rules outlined in chapter: GM DeviceNet/Indication
schema. Possible values are:
 2: If the control strategy is Torque Control.
 6: If the control strategy is Angle Control.
 NOT_DEFINED (-32768 if report format is Binary and blank if Binary): If the control
strategy is Undefined
Spindle Name
Name of the spindle that was used to tighten the bolt.
