Nomenclature Section 2-1
DIP Switch Function The DIP switch is used to decide the operating method of the Analog Input
Unit.
The following tables provides DIP switch settings for Analog Input Unit opera-
tion.
Input Range Settings
(Pins 1 to 8)
Input range settings can be made for all inputs.
Word Settings (Pin 9) The Analog Input Unit will occupy four words (64 points) when pin 9 is set to
ON. The Analog Input Unit will occupy two words (32 points) when pin 9 is set
to OFF.
Average Processing
Function (Pin 10)
Set pin 10 to ON to use the average processing function of the Analog Input
Unit. Set pin 10 to OFF if the average processing function is not used.
Caution All pins must be set before mounting the Analog Input Unit to the CQM1H/
CQM1.
An error will result if pins 1 to 8 are all set to OFF (i.e., if all input conversion is
prohibited).
When pin 9 is set to OFF so that the Analog Input Unit will occupy two words,
be sure to set pins 5 to 8 to OFF.
Do not touch any internal components other than the DIP switch.
The time required for the Analog Input Unit to convert data will not be short-
ened even if some inputs are prohibited or if pin 9 is set to OFF so that the
Analog Input Unit will occupy two words.
