with fixed allocations.
The following words are allocated in the master when the
DeviceNet Section is used as a slave with fixed allocations.

These bits in the CIO Area are used as work bits in programming to
control program execution. They cannot be used for external I/O.
Work Area
8,192 bits (512 words): W00000 to W51115 (W000 to W511)
Controls the programs only. (I/O from external I/O terminals is not pos-
sible.)
Note When using work bits in programming, use the bits in the Work
Holding Area
8,192 bits (512 words): H00000 to H51115 (H000 to H511)
Holding bits are used to control the execution of the program, and
maintain their ON/OFF status when the NSJ Controller is turned OFF
or the operating mode is changed.
Note The Function Block Holding Area words are allocated from

Auxiliary bits are allocated specific functions.
Temporary Area
16 bits (TR0 to TR15)
Temporary bits are used to temporarily store the ON/OFF execution
conditions at program branches.
