ItpResetEx

ItpResetEx 1:

The function block 'ItpResetEx' executes a channel reset, which deletes all existing tables of the NC channel. In contrast to the conventional ItpReset, an active channel is stopped first, before the reset is executed. This simplifies programming in the PLC, since no explicit check is necessary to ascertain whether the axes are still in motion.

ItpResetEx 2:

Outdated version

The sole purpose of the function block is to ensure compatibility with existing projects. For new projects please use the function block ItpResetEx2.

ItpResetEx 3: Inputs

VAR_INPUT
    bExecute       : BOOL;
    nGrpId         : UDINT;
    nChnId         : UDINT;
    tTimeOut       : TIME;
END_VAR

Name

Type

Description

bExecute

BOOL

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

nGrpId

UDINT

Group ID

nChnId

UDINT

Channel ID

tTimeOut

TIME

ADS timeout delay (the bBusy signal can be active for longer than tTimeOut)

ItpResetEx 4: 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).
