3. After making the DM settings from a Programming Device, it will be neces-
sary to either turn the power to the PLC OFF and ON, or turn ON the Spe-
cial I/O Unit Restart Bit in order to transfer the contents of the DM settings
to the Special I/O Unit.
Voltage/Current Range
Setting
When “1 to 5 V, 4 to 20 mA” is selected for the input signal range, either the “1
to 5 V” or “4 to 20 mA” range can then be selected by means of the D(m+35)
setting. Adjusting the factory-set voltage and current can improve the accu-
racy of current output specifications.
Reading Conversion
Values
Analog input conversion values are stored for each input number, in CIO
words n+5 to n+8.
Note For the CIO word addresses, n = CIO 2000 + (unit number x 10).
Use MOV(021) or XFER(070) to read conversion values in the user program.
Example 1 In this example, the conversion data from only one input is read. (The unit
number is 0.)
Example 2 In this example, the conversion data from multiple inputs is read. (The unit
number is 0.)
For details regarding conversion value scaling, refer to Scaling on page 366.
