values
Factory setting H0000
Example for CH1:
1. When b0=0, user can set OFFSET and GAIN values for
CH1 (CR#18, CR#24). When b0=1, inhibit the user
from modifying OFFSET and GAIN values for CH1.
2. b1=0 (factory setting, latched), b1=1 (not latched).
3. When b2 is set to 1, all settings will reset to factory
default settings.
#34 H’4022 O R System Version
Software version in hexadecimal. For example: H’010A
represents 1.0A.
#35~#48 System
used
O means latched. X means not latched. (available when using RS-485 communication, not available
when connected to a controller)
R means can read data by using FROM command or RS-485.
W means can write data by using TO command or RS-485.

Model Type
1. ELC-AN04ANNN model code = H’0088
2. Read the module code in the program to verify the correct extension module.
C R # 1 :
Configuration Word
The configuration word for the analog input module channels. There are 4 modes for each
channel, which can be set up individually. The default setting = H’000
For example, to set CH1 to mode 0 (b2 ~ b0 = 000), CH2 to mode 1 (b5 ~ b3 = 001), CH3 to
mode 2 (b8 ~ b6 = 010), and CH4 to mode 3 (b11 ~ b9 = 011), CR#1 must be set to H’0688.
The higher bits (b12 ~ b15) are reserved.
C R # 2 , 3 , 4 , 5 :
:
Number of samples for the average analog input values CH1 ~ CH4
Number of samples for averaging the CH1 ~ CH4 input signals. Note that the number of
samples in CR#2 ~ CR#5 only need to be written in once.
The setup range for this parameter for ELC-AN04ANNN: K1 ~ K100 samples. Default = K10
samples.
