This block can be used to monitor the availability of network devices or servers
To setup the Ping function block click on it in the page. You will see in properties under User interface a field for Ping address. Here you need to enter the IP address of the device you want to monitor.
With the parameter Tp you can define how many seconds after the previous successful ping the next ping is sent.
Likewise with the parameter Tt you can define how long after an unsuccessful ping the next ping should be sent.
And with parameter N you can set the maximum number of unsuccesful pings that can be sent before the output is switched off. The output is always active as long as the device is available and receiving pings.
When DisP is active you can stop pings being sent to the device.
Set up a caller service so the Miniserver will call you if the monitored device goes offline like in the example above.
More information on the caller service here.
