Either 0 to 100 mV or –100 to 100 mV.
Scaling required for the above input sig-
nals. (Any minimum and maximum values
can be set.) (8 inputs set separately.)
The value derived from carrying out the
following processing in order of the pro-
cess value data is stored in four digits
hexadecimal (binary values) in the allo-
cated words in the CIO Area.

Undefined.
When the process value is increased from 2% or less, the inrush input limit function
limits the increase for a set time. (It is available only for inputs of 0 to 100 mV.) This
function can be used to prevent sudden process value increases due to inrush cur-
rents caused by motor startup and so on.
Upper limit value: –32,000 to 32,000
Upper limit time: 0 to 100 s
Process value 2-point alarm (H, L), hysteresis, and ON-delay timer (0 to 60 s) are
available.
Calculates the moving average for the past four process values (every 200 ms), and
stores that value in the CIO Area as the process value.
Specifications
Input signal type and scaling to industrial
units are separate for each of the 8 inputs.
Note Input signal type and scaling to
industrial units are set in the DM
Area.
Example:
Input signal type: 0 to 100 mV; industrial
unit scaling: 0 to 500. DM Area settings
are as follows:
Input signal type: 0 (0000 Hex)
Industrial unit maximum value stored: 500
(01F4 Hex)
Industrial unit minimum value stored:
0 (0000 Hex)
