In each IOC can you send the output of the command

epicsPrtEnvParams

Subject: Re: Sequencer is not monitoring Pvs from another IOC

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 [X] procServ. Here is the environment variables.

#############declaring the EPICS environment LOCALLY#############################
export [X] EPICS_ROOT=/home/[X]ganesh/epics
export [X] EPICS_HOST_ARCH=[X]linux-x86_64
export [X] EPICS_BASE=$[X]EPICS_ROOT/[X]base-3.14.12.3

Hi [X] 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 [X] IOCs, operating
system([X]s), etc.  For example, one [X] IOC may be in a [X] VME crate and another [X] IOC run from a
[X]linux [X] pc; then you would have to be certain to set the environment variables correctly,
particularly [X] EPICS_CA_ADDR_LIST.

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

Dear All,

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

[X]____Here is what I am doing.____________________________________________________

Machine 1, [X] IOC1.

[X]DB_1.db has

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

[X]SEQ1.stt
Updated above [X] PV successfully.
-----------------------------------------------------------

Machine 2 [X] IOC2

[X]SEQ2.stt has

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

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

Please help.

Thanks and Regards

[X]Ganesh
