Analog I/O Units
Section 7-4
Handling Unit Errors
• When an error occurs in the Analog I/O Unit, analog input data will be
0000 and 0 V or 4 mA will be output as the analog output.
• CP-series Expansion Unit/Expansion I/O Unit errors are output to bits 0 to
6 of word A436. The bits are allocated from A436.00 in order starting with
the Unit nearest the CPU Unit. Use these flags in the program when it is
necessary to detect errors.
Programming Example
This programming example uses these ranges:
Analog input 0: 0 to 10 V
Analog input 1: 1 to 5 V or 4 to 20 mA
Analog output: 0 to 10 V or 4 to 20 mA

TIM
T0
TIM 0 will start as soon as power turns ON.
After 0.2 to 0.3 s (200 to 300 ms), the input for
TIM 0 will turn ON, and the converted data
from analog input 0 that is stored in word 2
will be transferred to D00000.
