When A40213 is ON, the content
of these bits depends upon the
status of A42615 (the Interrupt
Task Error Cause Flag).
1) A42615 OFF:
An interrupt task was executed
for more than 10 ms during I/O
refreshing of a C200H Special
I/O Unit or a SYSMAC BUS
Remote I/O Unit. A42600 to
A42611: contain the interrupt
task number.
2) A42615 ON:
An attempt was made to re-
fresh a Special I/O Unit's I/O
from an interrupt task with
IORF(097) while the Unit's I/O
is being refreshed by cyclic I/O
refreshing (duplicate refresh-
ing). A42600 to A42611: con-
tain the Special I/O Unit's unit
number.
When A40213 (the Interrupt Task
Error Flag) is ON, this flag indi-
cates the cause of the error.
A42615 will be ON if a Special I/O
Unit was refreshed from the in-
terrupt task while it was already
being refreshed.
A42615 will be OFF if the inter-
rupt task was executed for more
than 10 ms during I/O refreshing
of a C200H Special I/O Unit or a
SYSMAC BUS Remote I/O Unit.
When a CS/CJ-series CPU Bus
Unit Setting Error occurs, A40203
and the bit in this word corre-
sponding to the Unit's unit num-
ber are 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.
When a Special I/O Unit Setting
Error occurs, A40202 and the bit
in these words corresponding to
the Unit's unit number are turned
ON. Bits 00 to 15 correspond to
unit numbers 0 to F.
