Refer to 3-7-1 Adjustment Mode Operational Flow for further details.
Note For the CIO word addresses, n = CIO 2000 + (unit number x 10).
The input disconnection detection function can be used when the input signal
range is set for 1 to 5 V (4 to 20 mA).
3-6 Analog Input Functions and Operating Procedures
3-6-1 Input Settings and Conversion Values
Input Numbers The Analog Input Unit converts analog inputs specified by input numbers 1 to
8 (1 to 4 for CJ1W-AD041-V1) only. To specify the analog inputs to be used,
turn ON from a Programming Device the D(m) bits in the DM Area shown in
the following diagram.
Note There are only four inputs for the CJ1W-AD041-V1.
The analog input sampling interval can be shortened by setting any unused
input numbers to 0.
Sampling interval = (1 ms) x (Number of inputs used) (See note.)
