I have 100+ PLCs on the network and would like to ping them to get online or offline status. I don’t need any other information. The ping node with an array of all IPs slows down the whole node red server.
Is there any other way or flow example to get online or offline status of all the PLCs?
You could send the array through a split node, followed by a delay node set to rate limit of 1 message per second. Lastly, since some timeouts might occur, do not operate this any faster than the total number of PLC's + 30s for timeouts.
