7.1.2 Correspondence between Output Signals and Addresses in a
Module
In the analog output module ADA02A, a 12-bit digital value is written
into each of the following addresses to output the desired
voltage/current to its corresponding analog output.
(1) For PMC-N/Q (PMC for Series 15/F-D Mate)

D00-n corresponds to the 2
0
weight, while D11-n corresponds to the 2
11
weight.
However, D11-n corresponds to the code bit 2's complement
representation.
NOTE
When setting an I/O module address, this module
initial adress must be assigned to an even address.
To write a value that is to be converted from digital to
analog into a PMC program, be sure to write it in
words (16 bits).
