15-3-2 Related Auxiliary Area Flags
Bit Name Description Values
A434.00 Open-circuit
Detection Flags
When analog Input 0 (AD0) open-circuit Error
is detected, this bit will be changed to “1”.
0: No error
1: Open-circuit error detected
A434.01 Open-circuit
Detection Flags
When analog Input 1 (AD1) open-circuit Error
is detected, this bit will be changed to “1”.
A434.04 Analog Initial-
ization Com-
pleted Flag
The Analog Initialization Completed Flag will
be changed to “1” ON when initial processing
is completed.
If the system starts operating, use this flag in
the program to delay reading converted data
from analog inputs until the data is valid.
0: Initializing
1: Initialization completed
