Basic Program (Analog Input Unit)

Program outline
Using ch 0 to ch 5 (set for no execution of input conversion processing) of the analog
input unit, this program reads the analog input data to the data registers DT100 to DT105
using the preparation completion flag.
Converts the analog values 4 to 20mA that were read to the digital
values 0 to 13107 (if, for example, the analog input range was set to
4 to 20mA DC)
By the move instruction F0 (MV),
the contents of input relay areas
WX0 to WX5 are read to the data
registers DT100 to DT105.
Settings
Channels that execute analog input conversion processing
H1111: ch 0 to ch 3 are set for execution
H11: ch 4 and ch 5 are set for execution and ch 6 and ch 7 are not set for execution
