Built-in Analog Input
The CP1L-EL/EM CPU Units are equipped with 2 built-in analog inputs.
When a voltage of 0 to 10 V is applied to the built-in analog input terminal, the
voltage is converted from analog to digital and the PV in A642 and A643 can
be changed to any value within a range of 0 to 1000 (0000 to 03E8 hex).

Analog Input Signal
Ranges
Analog input data is digitally converted according to the input signal range as
shown below.
Note
When the input exceeds the specified range, the A/D conversion data will be
fixed at either the lower limit or upper limit.
■
0 to 10 V
The 0 to 10 V range corresponds to the hexadecimal values 0000 to 03E8 (0
to 1000). The entire data range is 0000 to 044C (0 to 1100).
