Subject: Ongoing work to get the FRG gauges readouts to EPICs channels 

I decided to create an independent service for the XGS data readout so we can get this to work first before trying to integrate into current system. After starting the service, I noticed that the EPICS channel were not updating as expected. So I started to debug the problem and managed to track it down to an ip socket connect() error, i.e. we get a connection error for the ip address assigned to the LAN port to which the XGS box was connected. After trying a few things and searching the internet, I think the error indicates that this particular LAN port is not yet configured. I reached this conclusion after noting that only a select number of LAN ports connected without issues and these are the ports that already had devices connected. So it must be the case that the LAN ports were somehow configured. The next step is to look at the IOLAN manual to figure out how to configure the ip port for the XGS controller. Fingers crossed.
