It could be perfectly legimate for the same PV name to appear in more than one IOC, as long as the IOCs are in different subnets or use different EPICS_CA_SERVER_PORT settings, which places the PVs in totally different namespaces. As long any PV Gateways between the namespaces either block or rename these PVs this is not necessarily an error. IRMIS does not currently know anything about different PV namespaces, so its standard crawlers shouldn't be flagging duplicate PV names as mistakes. Maybe there could be a switch to turn on such checking, or a per-IOC setting that indicates which namespace(s) (subnet+port) the PVs are being served into. With that addition, it should be possible to include PV gateways into IRMIS as well... - Andrew -- There is considerable overlap between the intelligence of the smartest bears and the dumbest tourists -- Yosemite National Park Ranger
