How to troubleshoot LAN connections on a control system


In order to check the connection on LAN we have "Live monitoring" in the Systems view, a helpful tool to see if commnuication is flowing through to your devices.

You are able to see wether periphial devices on the network or serial is alive and thus finding the ones that are not.

We are able to see if TCP, PJLink, Telnet and serial are communicating with the controller connected.

It is also possible to see the state of inputs and outputs, high/low, triggered/untriggered.

Watch the video and the description below to get started:

The way you get started is to press "Live Monitoring" in the Systems view.


Then, if you are sure you have the matching project loaded, just press "Start".

If you haven't got the latest project loaded or if you are in the field and want to load from the system, then press "Download project", this is possible from USB or the network.


When you press start you can see below, that the Inputs are being triggered (red=low, green=high). When the outputs are triggered they will turn red.

The LAN connection is shown with the green/red bullit indicating which device is not connected, in the example below the connection to the preamplifier is pulled and then reconnected (on LAN please allow approximately 10 seconds in order to reconnect)

On the serial connections you are able to see outbound and incoing communication indicated by arrows on the ports.
