ItpResetFastMFunc

This function block represents an alternative to Auto-reset or reset with another M-function (reset list during parameterization of the M-function). For the sake of clarity, mixed operation involving resetting with an M-function and this function block should be avoided.

The fast M-function nMFuncNo is reset with a rising edge at input bExecute. In the event of the M-function not being available, no error is returned.

	Outdated version The sole purpose of the function block is to ensure compatibility with existing projects. For new projects please use the function block ItpResetFastMFuncEx.

Inputs

VAR_INPUT
    bExecute       : BOOL;
    nChnId         : UDINT;
    nMFuncNo       : UINT;
    tTimeOut       : TIME;
END_VAR

Name	Type	Description
bExecute	BOOL	The command is triggered by a rising edge at this input.
nChnId	UDINT	Channel ID
nMFuncNo	UINT	Flying M-function that is to be reset.
tTimeOut	TIME	ADS Timeout-Delay

Outputs

VAR_OUTPUT
    bBusy     : BOOL;
    bErr      : BOOL;
    nErrId    : UDINT;
END_VAR

Name	Type	Description
bBusy	BOOL	This output remains TRUE until the function block has executed a command, but at the longest for the duration supplied to the 'Timeout' input. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.
bErr	BOOL	This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in 'nErrId'. Is reset to FALSE by the execution of a command at the inputs.
nErrId	UDINT	Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs. The error numbers in ErrId can be looked up in the ADS error documentation or in the NC error documentation (error codes above 0x4000).
