00:
−
10 to +10 V
01: 0 to 10 V
10: 1 to 5 V/4 to 20 mA (See note 2.)
11: 0 to 10 V
Select the input signal range 1 to 5 V/4 to 20 mA by wiring the connector or
terminal block conversion connector. The voltage/current input setting can
also be set using DM word m+52.
0: 1 to 5 V
1: 4 to 20 mA
Note 1. For the DM word addresses, m = (unit number x 100)
2. The input signal range of “1 to 5 V” or “4 to 20 mA” is switched using the
voltage/current switch.
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.
Reading Conversion
Values Analog input conversion values are read in 4-digit hexadecimal for each input.
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.)
