Is there a way to display the communication status between each datalogger and the collection PC where RTMC Pro is installed?
If your question is whether there is a way to view said data, then the best answer is to use the LoggerNet status Monitor application. If instead, you mean to display similar data within an RTMC project or generated web site, all of the status fields that the status monitor uses are available as data in the "__statistics__" data broker. There are tables within this grouping that report communications status and other informsation for every device in the network map including dataloggers.
RTMC Pro is often connected to LoggerNet software to collect and manage data from data loggers. You can open LoggerNet and check the Status Monitor or Logger Status section to see the connection status of each data logger.
