After you have set your Node ID's and IP Addresses for your Showstopper devices, you will want to configure them in Spikemark to easily see which E-Stop in your system is triggered.
Showstopper Status and Node configurations is only available in Spikemark 5 with Showstopper 4 Hardware.
Simply, Open the Showstopper Node Editor
Enter a name for each Node ID on the Network and Click to Check Box to make it Visible in the Showstopper Status Window
Organize your E-Stops into groups or groups of groups to provide organization for all the E-stop's in your system.
To Create a Group of Showstopper Nodes, open the Showstopper Group Node Editor
After assigning names to Node IDs and organizing them by groups, see your E-stop Statuses in the Showstopper Status Window.
