ScopeSetRecordLen

ScopeSetRecordLen 1:

The function block "ScopeSetRecordLen" can be used to configure the Scope View recording time. Currently this function can only be used if only one view (such as Scope View 1) is active in the application. Internally, an instance of the ADSWRITE function block is called.

VAR_INPUT

VAR_INPUT
    bExecute        :BOOL;
    fRecordLen      :LREAL;
END_VAR

bExecute:: The function block is activated by a positive edge at this input.

fRecordLen: The recording time in seconds for the Scope View that is to be configured.

VAR_OUTPUT

VAR_OUTPUT
    bBusy       :BOOL;
    bError      :BOOL;
    iErrorId    :UDINT;
END_VAR

bBusy: When the function block is activated this output is set. It remains set until and acknowledgement is received.

bError: If an ADS error should occur during the transfer of the command, then this output is set once the bBusy output is reset.

iErrorId: Supplies the ADS error number when the bError output is set.
