Status and error bits
Description
You use the "Technology object > Diagnostics > Status and error bits" diagnostic function in
the TIA Portal to monitor the status and error messages for the technology object. The
Diagnostics function is available in online operation.
The meaning of the status and error messages is described in the following tables. The
associated technology object tag is given in parentheses.
Encoder status
The following table shows the possible external encoder status values:
Status
Description
Enabled
The technology object is enabled.
(<TO>.StatusWord.X0 (Enable))
Homed
The technology object is homed. The relationship between the position at the technology
object and the mechanical position was successfully created.
(<TO>.StatusWord.X5 (HomingDone))
Error
An error has occurred at the technology object. Detailed information about the error is avail-
able in the "Error" area, and in the <TO>.ErrorDetail.Number and <TO>.ErrorDetail.Reaction
tags of the technology object.
(<TO>.StatusWord.X1 (Error))
Restart active
The technology object is being reinitialized.
(<TO>.StatusWord.X2 (RestartActive))
Encoder values valid
The encoder values are valid.
(<TO>.StatusSensor[n].State)
Online start value changed Data relevant for the restart has been changed. The changes will not be applied until the
technology object is restarted. (<TO>.StatusWord.X3 (OnlineStartValuesChanged))
Motion status
The following table shows the possible axis motion status values:
Status
Description
Done (no active job)
No active Motion Control job at the TO.
(Enable by "MC_Power" job excepted)
(<TO>.StatusWord.X6 (Done))
Homing job
The technology object is executing a homing job from the Motion Control instruction
"MC_Home".
(<TO>.StatusWord.X11 (HomingCommand))
