The respective read cycle (that is, the transfer of a complete result string) is
complete when ACTIVE takes on the value TRUE and either DONE or ERROR has
taken on the value TRUE (positive-going edge). If you want to start an additional
job while a read job is running, you have to abort the read job. This occurs by
calling the FB with COMMAND=W#16#0000. In this case, ACTIVE does not take
on the value FALSE. Depending on whether a result string is being transferred or
not, either DONE or ERROR takes on the value TRUE. If ERROR takes on the
value TRUE, ERRCODE does not take on the value DW#16#00010007.
Note
If an error occurs, set the processing unit to the STOP mode, correct and
acknowledge the error. You can then set the processing unit back to RUN mode
with a code change in a trained code (COMMAND = W#16#0001).
