Exchanging Data with the CPU Unit Section 7-5
The input disconnection detection function can be used when the input signal
range is set for 1 to 5 V (4 to 20 mA).
Allocation for Adjustment
Mode
For adjustment mode, set bits 00 to 07 in D(m+18) to 01 hex.
The allocation of CIO words and bits is shown in the following table.
Set Values and Stored
Values
Refer to 7-9-1 Adjustment Mode Operational Flow for further details.
Note For the CIO word addresses, n = CIO 2000 + (unit number x 10).
Input signal range Voltage/current
1 to 5 V 0.3 V max.
4 to 20 mA 1.2 mA max.
