No. Environment Language File name
1 Windows, Linux, etc. Python VZ20XSample07_EN.zip
2 FA -M3 Ladder VZ20XSample08_EN.zip
Refer to the sample programs when writing a program
to monitor measured values using function code 03.
The sample programs continuously read the CH1 to CH8 data of 40106 to
40121 from the VZ20X that is connected via Ethernet, by using a PC with
Modbus function code 03.
* See "Appendix" for details on preparing and running development
environments for sample programs.
The sample program can be downloaded from our website after entering
customer information.

4.4.2 Data Monitoring Example
Specify a register in which
the measured values of
VZ20X CH1 to CH8 are
continuous, and read out
the data.
Register number
(Reference no.)
Hex number
(hexadecimal)
Register name R/W Descriptions
40101 0064
Measured value time stamp
R
The time of measured values
can be read.
This setting is common to all
channels.
The coordinated universal time
or UTC can be read as a 64 -bit
unsigned integer.
40102 0065 R
40103 0066 R
40104 0067 R
40105 0068 Device status R
The device status of the VZ20X
can be read.
40106 0069
CH1 measured value
R
Measured values can be read
as 32-bit signed integers.
The range changes depending
on the input range.
