Logging directly from the midas logger to FTP is a bit cumbersome. In case of delays during login etc. this can throttle the whole DAQ chain.
What we use in our lab is to write to local disk, then use the lazylogger (https://midas.triumf.ca/MidasWiki/index.php/Lazylogger) to copy the
local files to a remote FTP server. This way we de-couple data taking from backup, making the system much more swift.

rb_xxx functions are midas event agnostic. The receiving side in mfe.cxx (lines 1418 in receive_trigger_event) however pulls one event at a time. If you
have some inconsistency I would put some debugging code there.

structure. Assuming a slow device frontend, its class driver should have a routine of type

Hi, Giorgio - I think you encountered a fundamental problem with what to do at the begin of
run. There are two ways of thinking about it.
|
|
02 Feb 2020, Pintaudi Giorgio, Info, Force triggering of idle routine of a frontend

Dear Konstantin,
thank you very much for the explanation. I already have an idea of how to solve my problem by bypassing the class driver altogether or by slightly modifying
the mfe.cxx frontend.
|
|
03 Feb 2020, Stefan Ritt, Info, Force triggering of idle routine of a frontend
|
It is important to note that slow control readout and sending of midas events are two separate things. Readout is done as fast as possible, even multi-threaded
if selected. On fast devices this can be 100 Hz readout rate and even more. This data is stored in an internal buffer. When one of the values changes by
more than the update threshold, then the ODB gets updated. The midas events are composed from this internal buffer when a new event has to be sent. This |

04 Feb 2020, Pintaudi Giorgio, Info, Force triggering of idle routine of a frontend
|
Dear Stefan,
thank you very much for the clarification. I knew about the DF_XXX flags and I am making good use of them in all my frontends. Anyway, what I really needed
was to change the readout rate depending on the run status (in particular DF_RUNNING or DF_TRANSITION).
|

Dear Giorgio,
ok, now I'm slowly getting your point.

07 Feb 2020, Pintaudi Giorgio, Info, Force triggering of idle routine of a frontend

Dear Stefan,
Thank you for the advice. I will try to modify the driver as you say. As for the dynamical change of readout rate, basically you are telling me that is
not achievable without dirty hacks like mine and it is better to find a way to avoid it.
|
|
09 Feb 2020, Stefan Ritt, Info, Force triggering of idle routine of a frontend
|
You dirty hacks will probably work, but what you REALLY want is to read out your HV always as fast as possible, not only during run transitions or ramping.
We had a case where a detector produced electrostatic discharges which only lasted for a second or so, and we were happy to detect this in spikes in the
HV current. With measurements of only one per minute we would not have realized that so quicky.

I had a look again at the issue. If you sett the event limit to zero in the EQUIPMENT list, then the idle() routine of your class driver is called as often
as possible. Typically with 100 Hz. It's then up to you what to do in the class driver. The hv_idle() routine of the HV class driver shipped in the distribution
for example read a channel more often if it has been changed recently. Look at the lines

Are there good reasons to not compile MIDAS with set(CMAKE_CXX_STANDARD 14)? So far this was an easier "fix" for me than to recompile ROOT with c++11. |

14 Jan 2020, Peter Kunz, Forum, EPICS frontend does not compile under midas-2019-09-i

I'm still trying to upgrade my MIDAS system to midas-2019-09-i. Most frontends work fine with the modifications already discussed.
However, I ran into some trouble with the epics frontend. Even with the modifications it throws a lot of warnings and errors (see attached log file). I
can reduce the errors with -fpermissive, but the following two errors are persistent:

I fixed the compiler errors in epics_ca.cxx, can you try again? (see https://bitbucket.org/tmidas/midas/commits/)
But, I do not see errors with ca_create_channel() and ca_create_subscription().

Hi Konstantin,
I have EPICS Base Release 3.14.8.2 and got your example running with it, though I had to make one change.
For some reason it wouldn't find libca.so, but when I linked the static library libca.a instead, it worked.

After upgrading to the lastes MIDAS version I got the DAQ frontend of my application running by changing all compiler directives from cc to g++ and using
#include "mfe.h"
extern HNDLE hDB |

Thanks for explaining this, Konstantin.

Actually now I see that
a4) poll_event() and interrupt_configure() have "source" as "int[]" instead of "int" (why did this work before?)

Re: MIDAS versions
Thanks for pointing that out. I wasn't actually aware that there is a release branch and a development branch.

For using the release branch read the messages in this thread. Most of the time, the develop branch is fine, except when we are developing something
new, and the only way to tell is to watch the git activity on bitbucket or see the release branch announcements I post on the midas forum.
