ItpResetFastMFunc
from library version 5.4.19
 | Outdated version The sole purpose of the function block is to ensure compatibility with existing projects.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.

BOOL |
The command is triggered by a rising edge at this input. |

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). |
