3.5.15 Analog Input Definitions
This section explains how to set the Analog Input Definitions.
„ Outline of the Analog Input Definitions
The AI-01 Module is equipped with 8 analog input (AI) channels. The overall input circuit is
isolated, but the channels are not isolated from each other.
It is possible to use 1, 2, 4, or 8 channels. Processing speed can be improved by selecting
fewer channels because it is not necessary for the CPU to scan all 8 channels.
Input servicing is performed at fixed intervals, once for each scan (high-speed or low-speed)
in the CPU-01 Module. Each channel can be set to the high-speed or low-speed scan inde-
pendently.
Set the scan timing and allocates registers to 4 analog input channels in the Analog Input
Definitions Window.
Three types of analog input ranges must be selected.
„ Opening the Analog Input Definitions Window
Open the Analog Input Definitions Window according to the procedure in 3.3 Basic Individ-
ual Module Definition Operations.
