Analog Output Units
Section 9-3
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 5 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.
