Variable |
Data type |
Description |
|---|---|---|
|
xInit |
BOOL |
Has the data structure already been initialized? Has to be checked by every access function. If the flag is still on FALSE, the FC_InitExceptionList function has to be executed. |
|
xQuitActive |
BOOL |
Is TRUE as long as a DiagQuit is active. See timQuitTimeout |
|
udiNumberOfActiveExceptions |
UDINT |
Number of exceptions entered into the exception list. |
|
xExceptionListHasChanged |
BOOL |
The content of the exception list has been changed. |
|
udiExceptionListChangeCounter |
UDINT |
Is incremented if the content of the exception list has been changed. |
|
astException |
ARRAY[1..Gc_udiMaxNumberOfExceptions] OF ST_Exception |
Field with active exceptions. Never access this field directly. Use the FB_CopyExceptionList POU to create a copy for yourself and work with it. |
|
astExct |
ARRAY[1..Gc_udiMaxNumberOfExceptions] OF ST_ExceptionElementInfo |
Additional information about the active exceptions. |
|
stOverflowException |
This exception is entered into the exception list if there is an attempt to enter too many exceptions (Gc_udiMaxNumberOfExceptions). |
|
|
tonQuitTimeout |
TON |
Function block that is required to delete the exceptions that are no longer active. |
|
timQuitTimeout |
TIME := T#300MS |
Adjustable time after which all the exceptions are deleted that are no longer marked as active. A value >= 300ms must be selected. It may be necessary to increase this time in the case of a great many of Sercos slaves or when modules are used that monitor slaves connected to field buses. You will notice this if you have to press the DiagQuit button several times in order to acknowledge all exceptions. In these cases, increase the time that it is set here by assigning the desired value to the variable in SR_MainMachine.Init_SubModules. |
|
astExceptionDelayList |
ARRAY[1..Gc_udiMaxNumberOfDelay] OF ST_Exception; |
List of delayed exceptions whose reaction is not yet active. Never access this field directly. Use the FC_CopyExceptionDelayList POU to create a copy for yourself and work with it. |
|
stExceptionDelayListExt |
ARRAY[1..Gc_udiMaxNumberOfDelay] OF ST_ExceptionDelayListExt; |
Additional information of the ExeptionDelayList. |
|
udiExceptionDelayListFirst |
UDINT |
Additional information of the ExeptionDelayList. |
|
udiExceptionDelayListFirstFree |
UDINT |
Additional information of the ExeptionDelayList. |
|
xExceptionDelayListHasChanged |
BOOL |
The content of the ExeptionDelayList was changed. |
|
udiExceptionDelayListChangeCounter |
UDINT |
Is incremented if the content of the ExceptionDelayList was changed. |
