FB_GetRtPerformanceData

The function block FB_GetRtPerformanceData can be used to determine the current RealTime Performance data of a TwinCAT system.

Inputs

VAR_INPUT
    bExecute : BOOL;
    bReset   : BOOL;
    tTimeout : TIME;
    sNetId   : T_AmsNetId;
END_VAR

Name	Type	Description
bExecute	BOOL	The function block is enabled by a positive edge at this input.
bReset	BOOL	A positive edge at bReset AND bExecute deletes the maximum of the RealTime Performance data.
tTimeout	TIME	States the time-out period that may not be exceeded by execution of the ADS command.
sNetId	T_AmsNetId	AmsNetId (AMS network ID) of the TwinCAT computer whose CPU usage is to be read. An empty string may be specified for the local computer.

Outputs

VAR_INPUT
    bBusy               : BOOL;
    bError              : BOOL;
    nErrorId            : UDINT ;
    nUsedCpuCount       : UDINT
    stRtPerformanceData : ARRAY [1..nMaxCpuCount] OF ST_RtPerformanceData;
END_VAR

Name	Type	Description
bBusy	BOOL	When the function block is enabled, this output is set and remains set until a feedback is received.
bError	BOOL	If an error occurs during the transmission of the command, this output is set after the bBusy output is reset.
nErrorId	UDINT	Returns the ADS error number when the bError output is set.
nUsedCpuCount	UDINT	Number of CPU cores used by TwinCAT
stRtPerformanceData	ARRAY [1..nMaxCpuCount] OF ST_RtPerformanceData	RealTime Performance data The constant nMaxCpuCount is in the ParameterList of the Tc2_Utilities Library and can be set between 1..64, default is 64. See Global parameters in the Tc2_Utilities Library.
