(18) List of Peripheral Faults (LPF) (Buffer memory address D0
H
to D1
H
,

to D3

: Un\G208 to Un\G209, Un\G210 to Un\G211)
Each bit corresponds to the peripheral fault occurrence status of the
corresponding slave address (1A to 31A, 1B to 31B).
When the bit is ON, it indicates that a peripheral fault has occurred in the slave
corresponding to that bit. (When any of the bits is ON, the peripheral fault bit of
the EC flag (buffer memory address: 10
H
) turns ON.)
When the bit is OFF, it indicates that a peripheral fault has not occurred in the
slave corresponding to that bit.
The peripheral fault slave list is a function compatible with AS-i Ver. 2.11.
For the peripheral fault detection conditions, refer to the manual of the slave
used.
