Re: error of beacon

Hi Azra,

I guess there are multiple Ethernet ports on the computer where the PLC ioc is running. Put the two lines below at the front of your ioc startup script (just after the line #!), then change “ioc-subnet-broadcast-ip …” based on your networking settings,  and the annoying CA beacon message should be gone.

epicsEnvSet("EPICS_CA_AUTO_ADDR_LIST", "NO")

epicsEnvSet("EPICS_CA_ADDR_LIST", “ioc-subnet-broadcast-ip such as 10.0.153.255”)

You need to find out the broadcast IP of your ioc (Channel Access) subnet: the command ifconfig on Linux should tell you what you should use.

I have been using this quick fix a lot and it works very well. Hope it work for you.
