 Functional Classification: Errors
Variable name _TaskName_Exceeded
Meaning Task Period Exceeded Flag Global/local Global
Function TRUE if the task period was exceeded.
FALSE if task execution was completed within the task period.
Note You cannot use this system-defined variable in the user program. It is used only to access task status for
data tracing from the Sysmac Studio.
Data type BOOL Range of values TRUE or FALSE
R/W access R Retained Not retained. Network Publish Not published.
Usage in user program Not possible. Related instruc-
tions
You can access this variable from the user program only with the following
instruction.
• GetMyTaskStatus
Variable name _TaskName_ExceedCount
Meaning Task Period Exceeded Count Global/local Global
Function Contains the number of times that the period was exceeded.
If the present value exceeds the maximum value of the data type, the present value returns to 0 and the count is
continued.
If 4294967295 is exceeded, the value returns to 0 and counting is continued.
Note You cannot use this system-defined variable in the user program. It is used only to access task status for
data tracing from the Sysmac Studio.
Data type UDINT Range of values Depends on data type.
R/W access R Retained Not retained. Network Publish Not published.
Usage in user program Not possible. Related instruc-
tions
You can access this variable from the user program only with the following
instruction.
• GetMyTaskStatus
Variable name _ErrSta
Meaning Controller Error Status Global/local Global
Function TRUE if there is a Controller error.
FALSE if there is no Controller error.
Note Do not use this variable in the user program. There may be a delay in updating it and concurrency prob-
lems in relation to the status of the function module. Use this variable only to access status through com-
munications from an external device. Refer to A-3-7 Meanings of Error Status Bits for the meanings of the
error status bits.
