Dear EPICS users, We installed Epics base 3.14.12.3 on a computer using Scientific Linux. Then we managed to create, build and run the IOC example application included with the EPICS base. Now, we would like to create one CAClient to access the PV. Then we configured the /etc/profile file and added the necessary lines: EPICS_HOST_ARCH="linux-x86_64" export EPICS_HOST_ARCH EPICS_BASE=/opt/epics/base-3.14.12.3 export EPICS_BASE PATH=$PATH:/opt/epics/base-3.14.12.3/bin/linux-x86_64 EPICS_CA_AUTO_ADDR_LIST=YES (tried this too, but it did not work) export EPICS_CA_AUTO_ADDR_LIST EPICS_CA_ADDR_LIST="192.168.163.97 192.168.163.255" export EPICS_CA_ADDR_LIST and we am unable to reach any PV in the example app included in Epics. We am running the example app by running st.cmd in terminal, we can see the PVs inside Iocshell but when I try to connect the PV to a graphical text monitor in MEDM, the Graphical Object is not connected to the PV inside the IOC. PV Info inside MEDM says: TYPE: TYPENOTCONN HOST: <disconnected> The PV name is correct, we think: rootHost:ai1.VAL and tried rootHost:aiExample1.VAL and they are not receiving any values from the IOC. When we try to run caExample we get the following errors: [root@Epics O.linux-x86_64]# ./caExample rootHost:ai1.VAL CA.Client.Exception............................................... Warning: "User specified timeout on IO operation expired" Context: "ca_pend_io failure" Source File: ../caExample.c line 20 Current Time: Tue Aug 19 2014 14:54:46.378283619 ..................................................................
