Jeff,

This worked. It did not seem to matter if I set the EPICS_CAS_SERVER_PORT = 5071 or not. It worked either way.

I did get errors on both IOC's though. They were basically the same whether I configured the EPICS_CAS_SERVER_PORT

Errors for IOC on default Port

Errors for IOC's on Port 5071

I also tried Andrews suggestion of not changing the port numbers on either IOC but then my edm screen would reconnect to one but not both IOC's if it became disconnected.

My intention is to be able to modularize my control processes to aid in troubleshooting and to have the flexibility to spread out processing if needed by moving IOC's between hardware. Is there a better way of doing this?

Thanks

EPICS_CAS_SERVER_PORT = 5071

Subject: Multiple IOC

I have two IOC's running on one linux PC.  One is using the default
ports and I changed the other's port using:

EPICS_CA_REPEATER_PORT=5070
EPICS_CA_SERVER_PORT=5071



I have been able to get an edm screen to see pv's from both IOC's by
changing the environment variable:

EPICS_CA_ADDR_LIST=nnn.nnn.nnn.nnn nnn.nnn.nnn.nnn:5071


I have not been able to get the two IOC's to see each others PV's.  Any
ideas how I would be able to do this?

Thanks
