When an error occurs in a data
exchange between the CPU Unit
and a CS/CJ-series CPU Bus
Unit, the CS/CJ-series CPU Bus
Unit Error Flag (A40207) is
turned ON and the bit in A417
corresponding to the unit number
of the Unit where the error oc-
curred is turned ON. Bits 00 to 15
correspond to unit numbers 0 to
F.
The CPU Unit will continue oper-
ating and the ERR/ALM indicator
on the front of the CPU Unit will
flash.

Board Error Flag (A40208) and
the appropriate bits in A424 will
be turned ON.

Not used.
A42504 When there is an error in an Op-
tical I/O Unit (excluding Slave
Racks), the status of A42504
(ON or OFF) indicates whether
the Unit is allocated high or low
bytes.
1: High
0: Low
