Re: Sequencer is not monitoring Pvs from another IOC

[Ganesh Jangir <ganesh.jangir@tcs.com>]

Hi Pierrick, Benjamin

Thanks for the mail. I made an clean ioc using makeBaseApp.pl -t ioc <name> , makeBaseApp.pl -i -t ioc <name> . Added Db files and Sequencer files followed by successful make.

I am using
Epics base-3.14.12.3
Sequencer seq-2.1.16
OS: Linux Fedora 19  64bit

I am not using procServ. Here is the environment variables.

#############declaring the EPICS environment LOCALLY#############################
export EPICS_ROOT=/home/ganesh/epics
export EPICS_HOST_ARCH=linux-x86_64
export EPICS_BASE=$EPICS_ROOT/base-3.14.12.3
export EPICS_EXTENSIONS=$EPICS_ROOT/extensions
export EPICS_CA_ADDR_LIST="192.168.8.2 192.168.8.3 192.168.8.4 192.168.8.5"
export MOTIF_LIB=/usr/lib64/

export SEQ=$EPICS_ROOT/extensions/seq-2.1.16

export PATH=/sbin:/bin:/usr/sbin:/usr/bin:$file:$EPICS_ROOT/base-3.14.12.3/bin/linux-x86_64:/bin/linux-x86_64

Hi Ganesh,
In order to get an answer from the experts, you will likely need to provide more information;
namely, version number of the software, the hardware configurations of the IOCs, operating
system(s), etc.  For example, one IOC may be in a VME crate and another IOC run from a
linux pc; then you would have to be certain to set the environment variables correctly,
particularly EPICS_CA_ADDR_LIST.

Are you running these IOCs from procServ?  I'm asking because I have a similar issue.
Cheers,
Pierrick

Dear All,

Sequencer in one IOC, is not able to monitor, PV from another IOC on the same network. However these PVs are accessible by caget and camonitor on both machines.


____Here is what I am doing.____________________________________________________

Machine 1, IOC1.

DB_1.db has

record(waveform, "CMD_FIELD")
{    field(DESC, "command")
    field(NELM, 16000)
    field(FTVL, CHAR)
 }

SEQ1.stt  
Updated above PV successfully.
-----------------------------------------------------------


Machine 2 IOC2

SEQ2.stt has

char CMD_[16000];
assign CMD to "CMD_FIELD";
monitor CMD;
evflag cmdDFlag;
sync CMD cmdDFlag;


But not able to access the PV. It works only when I am creating this PV in IOC2.


Please help.


Thanks and Regards

Ganesh
