Outdated version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.

Description

A rising edge at input bExecute resets the fast M-function nMFuncNo. In the event of the M-function not being available, no error is returned.

This function block represents an alternative to Auto-reset or reset with another M-function (reset list during parameterization of the M-function). For reasons of transparency, mixed resets using an M-function and this function block should be avoided.

Input

Data 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

Output

Data 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).
