3.1 Outline
Settings and Items to Check Before Starting
Before connecting, use VZ Configurator to configure items such as
the VZ20X communication settings.
Precautions on the Use of Sample Programs
Sample programs are helpful tools to refer to when communicating
with VZ20X.
Visual Studio 2019 and Python development environments are
required when using sample programs.
Sample programs are intentionally written to be easy to understand.
Perform error processing, array creation, and other
tasks
as
necessary.
This section describes the
work flow
for data monitoring.
First, set the time for the VZ20X.
Next, send the monitoring start communication
command with FC=70.
After that, send the measured value acquisition
communication command with FC=71. In the case of a
1 ms data acquisition interval, send the first measured
value acquisition communication command within 2
seconds of the monitoring start communication
command.
Convert the measured values after they are acquired.
Repeat the measured value acquisition and conversion
operations the required number of times.
To stop monitoring the measured values, send the
FC=70 communication command to terminate the
process.
For details, refer to "7.2
Ethernet Communication
" in the
Model VZ20X Analog Sensing Unit User’s Manual.
