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.
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 shortened
even if some inputs are prohibited or if pin 9 is set to OFF so that the Analog Input
Unit will occupy two words.
