Support for redundant IOCs has never been part of the core EPICS code nor is it maintained by the core developers group. It was developed by/for DESY but they don?t publish the code online. They are apparently no longer able to maintain it themselves, and we don?t know if it works with recent versions of EPICS at all (to be honest it probably won?t). The last discussions here about it were in this message<https://epics.anl.gov/tech-talk/2017/msg01265.php>, this one<https://epics.anl.gov/tech-talk/2017/msg01607.php> and this<https://epics.anl.gov/tech-talk/2019/msg01749.php> unanswered question.

If there are sites that are relying on this software they should probably get together and try to find some funding or developer expertise to maintain it.

I have several PILATUS detectors running areaDetector 1-9 (on various OSs - OpenSUSE 10, CentOS 6). I am wondering about the feasibility of upgrading to the latest version of areaDetector. In particular does ADPilatus require a specific version of camserver?

Thanks,

We must be missing something obvious but synApps won?t install on Ubuntu for us.  The problem step is make release hangs forever.  Some problem with perl but we don?t know what.

Steps:
install ubuntu 18 LTS
Install EPICS7
Unzip the synApps (6_1) tar file and edit config files
run ?make release?
Wait forever?.

Exact same procedure installs fine on Centos 7.  Since there isn?t a lot of chatter about this, it seems like we?re missing a step somewhere.  Anyone know what we need to do?

Thanks.

Randall

ADPilatus attempts to determine the camserver version and behave correctly for any version. We have some very old camserver versions on 100K units with the latest ADPilatus.

Hi,

We are trying to build https://github.com/dls-controls/ADEiger/tree/1.8.

We have an Eiger1 X 500k which recently got repaired and Dectris shipped with their 1.8 API. We see a few strange things.

1.) We can only get the device driver (EigerDetectorConfig) to load if eigerModel=2. I doubt they upgraded with the new Eiger2 chips, but I am double checking with Dectris. If we use eigerModel = 1 we get some Rest API errors.

2.) eiger2.template has an include for eigerBase.template. It says it can't open eigerBase.template. See below. We bypassed this problem by merging eigerBase.template into eiger1.template. Most PV fill except Firmware Version and Serial Number and the detector takes images ok. If we use eiger2.template (and eigerModel=2) we have more problems (not shown below or quantified yet).

Thanks,
Nino

Subject: get the timestamp of a record as a human-readable string and
        restore it after rebooting
Message-ID: <1D9A2BBC-CC1E-461D-8A88-C20C0F8A7AFB at bnl.gov>
Content-Type: text/plain; charset="utf-8"

Hello everyone,

Since the field .TIME is internal to a record (e.g. recordA), it seems not straightforward for a string record (e.g. recordB) to directly get the timestamp of recordA as a human-readable string, although it is straightforward for a Python program to put a record?s timestamp as a string.

I managed to use ?Soft Timestamp? together with ?TSEL? to get the timestamp of a not-on-the-same-IOC record as a human-readable string. See below:
record(calcout,"recordA -Calc_") {
   field(INPA,"recordA CP")
    field(CALC,"1")
    field(OOPT,"Transition To Zero")
    field(OUT, "recordB.PROC")
}

record(stringin, "recordB")
{
    field(DTYP,"Soft Timestamp")
field(PINI,"YES")
#without TSEL, recordB will not be exactly the same as recordA?s timestamp
    field(TSEL,"recordA.TIME")
    field(INP, "@%Y-%m-%d %H:%M:%S.%f")
    info(autosaveFields_pass0, "VAL")
}

recordA is a bi record running on another IOC (that is why I use CP in INPA). I want to use recordB to latch the timestamp of recordA when recordA?s value goes from 1 to 0. Everything seems working as expected. However, there is one problem with autosave. After the IOC is rebooted, the value of recordB is <undefined>, it is not restored to its saved value although I see the saved value ?2020-08-15 01:18:55.236900451? in the *_pass0.sav file before I reboot the IOC. I also tried to use pass1, the same result <undefined>.
$ caget -a recordB
recordB     <undefined> <undefined>

I see some errors during the rebooting. I guess the reason why I get ?dbGetTimeStamp failed? is that the CA link is not established yet before initial process (PINI=YES). However, when I look through the code https://github.com/epics-base/epics-base/blob/3.15/src/ioc/misc/iocInit.c, dbCaLinkInit() is indeed before initialProcess().
reboot_restore: entry for file 'settings_pass0.sav'
reboot_restore: Found filename 'settings_pass0.sav' in restoreFileList.
*** restoring from './as/save/settings_pass0.sav' at initHookState 6 (before record/device init) ***
reboot_restore: done with file 'settings_pass0.sav'
recGblGetTimeStamp: dbGetTimeStamp failed, recorddB.TSEL = recordA

How do I solve this problem? Any suggestions are appreciated!
I am using Base-3.15.6-2 and autosave-5.9 if versions matter.

Thanks,
Yong Hu
