IOWR/IORD-instruction errors
IOWR/IORD-instruction errors are detected by the Unit after they have been
issued from the ladder program to the High-speed Counter Unit. IOWR-instruc-
tions are used to change Counter settings of the Unit. In case you specify faulty
operands in the IOWR-instruction the Unit reports this as an error. IORD-instruc-
tions only generate an error in case an invalid Control Code or an invalid number
of words is specified.
