Introduction
The MicroSmart provides analog I/O control capabilities of 12- through 16-bit resolution using analog I/O modules.
This chapter describes the system setup for using analog I/O modules, WindLDR programming procedures, data register
device addresses for analog I/O modules, and application examples.
For hardware specifications of analog I/O modules, see page 2-55.
System Setup
The MicroSmart CPU module can be used with a maximum of seven expansion I/O modules, which include digital I/O
modules and analog I/O modules.
Quantity of Applicable Analog I/O Modules
The quantity of the analog I/O modules that can be connected to the MicroSmart CPU module depends on the model of
the MicroSmart CPU modules as listed below:

Note:
FC5A all-in-one 24-I/O type CPU modules cannot use analog I/O modules in combination with the AS-Interface master module
(FC4A-AS62M) and/or expansion RS232C/RS485 communication module (FC5A-SIF2 or FC5A-SIF4). When using these modules in com-
bination with analog I/O modules, use the slim type CPU module.
The all-in-one 24-I/O 12V DC type CPU module cannot use analog I/O modules.
