[Input: digital, analog] Block function code setting
■ Lock selection, function 1, function 2 (U01, U04, U05, etc.) (digital,analog)
The following items are available as function block.
Note that if the upper and lower limits are identical, there are no upper and lower limits.

4005 LPF
(Low pass filter)
with enable
Value of an analog input 1 is filtered through LPF
(time constant U04) when the digital input 1 is “1”.
When the digital input 1 is “0”, the analog input 1 is
directly output.
(LPF maintains the previous output value. Therefore,
when the digital 1 input changes from 0 to 1, the
output will be the value with the previous output value
added as the initial value of LPF.)
(No upper/lower limiter)

0: No filter
0.01 to 5.00s
Fixed as 0
4006 Rate limiter with
enable
Value of an analog input is limited with change rate
specified in functions 1 and 2 when the digital input 1
is “1”. When the digital input 1 is “0”, the analog 1
input is directly output. When setting the initial value,
carry out an operation with the initial value for input 1
and 0 applied to input 2. Then, reflect the result as the
initial value (= previous output value) with 1 applied to
input 2.
During the initialization or when the CLC terminal is
ON, the previous output value is cleared to 0.

5000 Selector 3 Function to select analog input 2 based on “SO01” to
“SO200”.
Step No. Not required
5100 Selector 4 Function to select analog input 1 and “SO01” to
“SO200” based on digital input 1.
Step No. Not required
6001 Reading
function codes
Function to read the content of arbitrary function
code. Use the 1st function code (such as U04) to
specify a function code group, and the 2nd one (such
as U05) to specify the last two digits of the function
code number. For the function code settings, refer to
“ Configuration of function codes” in page 5-270.
Both input 1 and input 2 are not used. Data formats
that can be read correctly are as follows (the values
are restricted between -9990 and 9990 and, for [29],
20000 is indicated as 100%):
[1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [12], [22], [24],
[29], [35], [37], [45], [61], [67], [68], [74], [92] and [93]
Data formats other than the above cannot be read
correctly. Do not use any other format.
