DM-configuration errors can be cleared by correcting the faulty settings in Data
Memory and consecutively transferring the new configuration data again to the
Unit. To transfer the configuration data you can choose from one out of two possi-
bilities:
•
Turn the power of the CJ-series PLC system ON.
•
Restart the High-speed Counter Unit (refer to 4-1-2 "Special I/O Units Restart
bits").
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.

Description
The Control Code that is specified in the
IOWR/IORD-instruction is not supported by the
High-speed Counter Unit. The Invalid Control
Code is reported in Error Code 2.
The number of words that is specified in the
IOWR/IORD-instruction is faulty. The Control
Code of the instruction for which the invalid
number of words is specified is reported in
Error Code 2.
Two problems can cause this error. The Z-
Reset Mode that you specified is not in the
valid range (0-1). It is also possible that you
issued an IOWR-instruction to change the
Maximum or Minimum Count Value of a
Circular or Linear Counter, causing one or
more of the already defined Range Limits or
Comparison Values to be outside the new
Counting Range. Counter No. indicates the
number of the Counter.
The Lower Count Limit of the Linear Counter is
not a negative value and/or the Upper Count
Limit is not a positive value.
The Counter Value issued with the IOWR-
instruction is outside the counting range of the
Counter. Counter No. indicates the number of
the Counter.
Upper Rate Range Limit
Limit. Counter No. indicates the Counter
number.
