Isolated Analog Output Modules
No special I/O configuration (SPIO CONFIG) information is required.
The module ID code automatically assigns the correct number of input
and output words for the processor to access.

Example – If you want to reconfigure channel 2 on your module, and it
is in slot 4 of the SLC chassis, you would modify the configuration word
at address O:4.5. Alternatively, if you want to obtain the status of channel
2, you would check the status word at address I:4.6.
