Continuous Poll button

Stop button
to stop continuous polling.
You can open as many monitor windows as you wish, either
for different sites, or for the same site using different data
sets. An open data monitor window is linked to the current
site and does not change if you select another site in the site
list.
You can view acquired data in a tabular form or in a graphical
form as a data trend.

automatically when a communication error occurs, otherwise
polling stops until you restart it manually.
