Work Area (W)
The Work Area is part of the internal memory of the CPU Unit. It is used in programming. Unlike the
input bits and output bits in the CIO Area, I/O to and from external devices is not refreshed for this area.
The Work Area contains 12
8
words with addresses ranging from W0 to W127.
It is sometimes necessary to use the same set of input conditions many times in the same program. In
this case a work bit can be used to store the final condition to simplify programming work and program
design.
•
Bits in the Work Area can be force-set and force-reset.
•
The contents of the Work Area will be cleared in the following cases:
•
When the operating mode is changed between PROGRAM or MONITOR mode and RUN mode
•
When the PLC power is reset
•
When the Work Area is cleared from the CX-Programmer
•
When PLC operation is stopped due to a fatal error other than an FALS error occurs. (The con-
tents of the Work Area will be retained when FALS is executed.)
