ST_CanContinueWriting - General Information

Overview

Type:	Data structure
Available as of:	1.1.2.0
Inherits from:	-

Description

Substructure, that in ST_DiagnosticsManagerToDiagSource Provides write blockage between different functions to help prevent multiple write access to file system resources

Structure Elements

Variable	Data type	Description
xIsInit	BOOL	TRUE shows that the internal structure (calculated performance characteristic values) is reset for the start of a new cycle.
xCanContinue	BOOL	Is set by the diagnostic manager If FALSE, writing is no longer permitted. The detected error is specified in more detail using xRamDiskFull, xCycleTimeover.
xCycleTimeOver	BOOL	Is set by the diagnostic manager. Indicates the detected error of xCanContinue: reports a cycle timeout
xRamDiskFull	BOOL	Is set by the diagnostic manager. Indicates the detected error of xCanContinue: reports a full ramdisk
udiMaxTime	UDINT	Is set by the diagnostic manager
udiStartTime	UDINT	Is set by the diagnostic manager Prompt for cycle start time (for internal performance calculation)
xMinLimitMode	BOOL	If TRUE, the "MinLimitMode" calculation is used at the start of the write process. This stops write processes if the Gc_udiMinLimitRamDiskFree memory is exceeded. Otherwise (FALSE) Gc_udiLimitRamDiskFree stops write processes if the memory is exceeded.
udiNumberOfCallsUntilCycleTimeOver	UDINT	Internal parameter
audiHistory	ARRAY[1..Gc_udiCycleHistorySize] OF UDINT	Internal parameter Saves characteristic values already calculated
xCycleTimeEmergencyMode	BOOL	If TRUE, udiMaxTime is set to 5/6 of the expected cycle period. Usually (FALSE) 1/2 of the expected cycle period is set.
