Work Area - Omron CJ2 CPU UNIT SOFTWARE User Manual

6 I/O Memory Areas

6-10 Work Area

The Work Area contains 512 words with addresses ranging from W0 to W511 for words and W0.00 to
W511.15 for bits. Words in this area cannot be used for I/O with external I/O terminals. They can be
used internally in the program.
There are also unused words in the Internal I/O Area in the CIO Area (CIO 1300 to CIO 1499 and CIO
3800 to CIO 6143) that can also be used in the program. The unused words in the CIO Area, however,
may be allocated to new functions in future versions of the CPU Units. Always use any available words
in the Work Area first, before using words in the Internal I/O Area.
