VAR_INPUT
    CLEAR       : BOOL;
END_VAR

CLEAR : With a rising edge at this input an indication is reported as processed and the outputs of the ADSWRITEIND function block are reset ( DATAADDR = 0, LENGTH = 0 !). A falling edge releases the function block for the processing of further indications.
