2. The input format used for adjustment is as follows:
Set Values and Stored
Values
Refer to 2-7-1 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).
