Inputs

Name	Type	Description
bPersistent	BOOL	If the value is `TRUE`, the internal data is stored persistently.

Outputs

Name	Type	Description
ipResultMessage	I_TcMessage	Contains more detailed information on the current return value. This special interface pointer is internally secured so that it is always valid/assigned.
bError	BOOL	This output is `TRUE` if an error occurs.
bNewResult	BOOL	When a new result has been calculated, the output is `TRUE.`
bConfigured	BOOL	Displays `TRUE` when the function block is successfully configured.
fMin	LREAL	Minimum of the input values.
fMax	LREAL	Maximum of the input values.
fAvg	LREAL	Average of the input values.
fbTimeMin	FB_ALY_DateTime	Timestamp of `fMin`.
fbTimeMax	FB_ALY_DateTime	Timestamp of `fMax`.

Methods

Name	Definition location	Description
Call()	Local	Method for calculating the outputs for a specific configuration.
Reset()	Local	Resets all internal states or the calculations performed so far.
SetChannelValue()	Local	Method for passing values to the algorithm.

Sample

VAR
    fbMinMaxAvg : FB_ALY_MinMaxAvg_1Ch;
    fbSystemTime : FB_ALY_GetSystemTime;
    nInput : INT;
END_VAR

// Get current system time
fbSystemTime.Call();

// Call algorithm
fbMinMaxAvg.SetChannelValue(nInput);
fbMinMaxAvg.Call(fbSystemTime.tSystemTime);
