Data is exchanged with CPU Bus Units once each cycle during I/O refreshing,
which occurs after program execution. (Words in this data area cannot be
refreshed with IORF(097).)
Each CPU Bus Unit is allocated 25 words based on its unit number, as shown
in the following table.
The function of the 25 words depends upon the CPU Bus Unit being used. For
details, refer to the Unit’s operation manual.
Words in the CPU Bus Unit Area that aren’t allocated to CPU Bus Units can
be used only in the program.
Bits in the CPU Bus Unit Area can be force-set and force-reset.
The contents of the CPU Bus Unit Area will be cleared in the following cases:
1. The operating mode is changed from PROGRAM to RUN or MONITOR
2. The PLC’s power supply is cycled and the IOM Hold Bit is OFF or not pro-
3. The CPU Bus Unit Area is cleared from a Programming Device.
4. PLC operation is stopped when a fatal error other than an FALS(007) error
By default, the CPU Bus Unit Area is cleared when power is interrupted or the
CPU Unit is restarted.
