I do not understand what you are doing. If you are offline, there is no TMFE singleton instance,
there is nothing TMFeRpcHandlerInterface to attach to, there is nobody to call TMFeRpcHandlerInterface methods.

Dear experts,
in the CYGNO experiment, we readout CMOS cameras for optical readout of GEM-TPCs. So far, we only developed the readout for a single camera. In the
future, we will have multiple cameras to read out (up to 18 in the next phase of the experiment), and we are investigating how to optimize the readout |

So I started our DAQ with an updated midas, after ca. 6 months+.
No issues except all FEs complaining about the Alarm ODB structure.

Would be worthwhile mentioning the git commit hash or tag you are using.

Just to be clear, it seems that your "EPICS Frontend" was either not recompiled against the new midas yet or the old binary is being run, but "SC Frontend"
is using the new midas.

Sorry to intervene there, but the FEs are usually compiled against libmidas.a . Therefore you have to compile midas, usually do a "make install" to update
the libmidas.a/so, then recompile the FEs. You probably forgot the "make install".

Dear all,
I want to control (start / stop / monitor its stdout and stderr) an external process (systemd / EPICS IOC shell script) from within MIDAS.

Dear all,
Stefan wants to run an external EPICS driver process as a detached process and somehow "glue" it to midas to control it. Actually a
similar requirement led to the development of MIDAS in the '90s. We had too many configuration files lying around, to many process to control and interact |

I am updating TWIST to the latest MIDAS and when I load a saved .odb file, I get
these messages. Their text ought to say where and what strings it does not like.
