Analog Output Units Section 7-3
Handling Unit Errors • When an error occurs at the Analog Output Unit, the analog output will be
0 V or 0 mA. If a CPU Unit fatal error occurs when analog outputs are set
in the 1 to 5 V or 4 to 20 mA range, 0 V or 0 mA will be output for a CPU
error I/O bus error, and 1 V or 4 mA will be output for all other errors.
• CP-series Expansion 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.

TIM0005 is started when the power is
turned ON. After 0.2 s (200 ms) elapses,
the TIM0005 contact turns ON, and the
data stored in D100 will be moved to
102 as the conversion data for analog
output 1.
