When the number of communication
retries has exceeded the upper limit
Product diagnosis
By connecting the base and PC, you can set up the product/wireless
communication and check the communication status on the web
screen. Log data of the number of wireless communication retries and
of the received signal strength can be generated from the web screen
and downloaded in a CSV file. The wireless
environment and installation location can
be optimized by checking the number of
retries and the received radio wave
intensity.
∗
Refer to the logging function on page 4.
The log files showing the number
of retries or the received radio
wave intensity can be downloaded
in the form of a CSV file.
