Note
If the IOM Hold BIt (A50012) is ON, the contents of the CPU Bus Unit Area
won’t be cleared when a fatal error occurs or the operating mode is changed
from PROGRAM mode to RUN/MONITOR mode or vice-versa.
If the IOM Hold BIt (A50012) is ON and the PLC Setup’s “IOM Hold Bit Status
at Startup” setting is set to protect the IOM Hold Bit, the contents of the CPU
Bus Unit Area won’t be cleared when the PLC’s power supply is cycled.
The Inner Board Area contains 100 words with addresses ranging from
CIO 1900 to CIO 1999. Words in the Inner Board Area can be allocated to a
Duplex Inner Board to transfer data such as the operating status of the Unit.
All 100 words must be allocated to just one Inner Board.
1. The Inner Board Area is used for Inner Boards only in Single CPU Systems
2. The user cannot mount Inner Boards into CPU Units for Duplex CPU Sys-
Data is exchanged with the Duplex Inner Board once each cycle during nor-
mal I/O refreshing, which occurs after program execution. Depending on the
type of Inner Board that is mounted, data can also be refreshed directly.
The function of the 100 words in the Inner Board Area depends upon the
Duplex Inner Board being used. For details, refer to the Board’s Operation
Manual.
When the words in the Inner Board Area aren’t allocated to an Duplex Inner
Board, they can be used only in the program.
Bits in the Inner Board Area can be force-set and force-reset.
The contents of the Inner Board Area will be cleared in the following cases:
1. The operating mode is changed from PROGRAM mode to RUN/MONITOR
2. The PLC’s power supply is cycled and the IOM Hold Bit is OFF or not pro-
3. The Inner Board 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 Inner Board Area is cleared when power is interrupted or the
CPU Unit is restarted.
If the IOM Hold BIt (A50012) is ON, the contents of the Inner Board Area
won’t be cleared when a fatal error occurs or the operating mode is changed
from PROGRAM mode to RUN/MONITOR mode or vice-versa.
