General Announcement:
- From PRC, Maurizio V. and Raul V. have no new things to report, apart of the HXRSS difficult tuning.
- As DRC, Luis Maia says the main points were discussed (see below).

CTRL:
- Friday heard from Desy an update on servers that hold DOOCS and uTCA has to be done, and is planned for tomorrow. In case it is not transparent, the DOOCS servers will need 
to be restarted from our 
side.

DA:
- Nothing to report.

EEE:
- uTCA system to be restarted in case Tuesday's intervention affects it.

VAC:
- Everything is fine.

XPD:
- Nothing to report.

DET:
- Nothing to report.

ITDM: 
- Nothing to report.
- Related to Tuesday's updates with JDDD: in case of issues one option is to redefine the variables in the servers, as once tested.

XRO:
- Nothing to report.

LAS:
- Not present.

UNSYS:
- Everything is fine.
- Issues with lost of high level controls in the last blue week: not fully understandable why the fiber optics was lost.

SPB:
- Pulse energy during the nights is low; started with 1mJ and later dropped to ~600uJ.

FXE:
- Digitizer problem during the week was solved:
This occurred when a change of bunch number was requested; the digitizers are reconfigure via mid-layer device whenever number of pulses/frequency is updated. 
It is not clear if this was the cause of the issue. DOC reboot the hardware which resume data acquisition. 
Today (Monday) morning FXE noted that another mid-layer device was not displaying digitizer data properly; since the digitizers are the base class, it could be that 
communication was not reinitiated after the hardware reboot. Re-instantiating the mid-layer fix the issue.
- A temperature drift on the Mono is still to be investigated and XRO is aware of it.

MID:
- Nothing to report.

HED:

SCS:

CTRL is prepared for corrective actions if needed (restarting DOOCS devices in Karabo).
- Bridges Karako-DOOCS may need to be restarted with the new name server (Flash default). Shall be further investigated if this would be the case. 

DA:
- All fine at DA.

EEE:
