The alive record by itself isn't very useful. You need a remote server that listens for the heartbeat UDP messages generated by the alive record, which is what is specified by ALIVE_SERVER above. When I wrote the record, I assumed people would want to write their own remote server code for interacting with alive record from IOCs, although I'm not sure if that happened much. I released the server code as used by the BCDA group of the Advanced Photon Source earlier this year, which I wrote when I was in that group. You can find information on it and how to use it at https://epics-alive-server.github.io/ . About SEVR, I unfortunately ignored alarms when I wrote the record, as alarms didn't make sense for how it worked. I will look into fixing those alarm fields. So you can ignore SEVR being INVALID, as it doesn't signify a problem. Dohn Arms
