Analog Output Units
Section 7-3
• 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.

Analog Output Units
Each CP1W-DA041/CPM1A-DA041 Analog Output Unit provides four analog
outputs.
• The analog output signal ranges are 1 to 5 V, 0 to 10 V, -10 to +10 V, 0 to
20 mA, and 4 to 20 mA. The resolution is 1/6,000. The open-circuit detec-
tion function is activated in the ranges of 1 to 5 V and 4 to 20 mA.
• The Analog Input Unit uses four output words, so a maximum of three
Units can be connected.
