Modbus Protocol
Modbus is a serial communications protocol
originally published by Modicon [1979] (Schneider Electric) for use with PLCs.
Simple and robust - de facto standard communication protocol for connecting industrial electronic devices.
Modbus TCP / UDP
a Modbus variant used for communications over TCP/IP networks, connecting over port 502
does not require a checksum calculation as lower layers already provide checksum protection

Python ModBus Client
pymodbus module
First investigated option
Complete software, covering a variety of the protocol’s versions
Documentation & Github
Very complete and nice software
Unfortunately…
I did not figure out how to really make it work (or not yet ) !
Because of the simplicity of the protocol, I implemented it
For Binary format data
A big thanks to Steve !

Python ModBus Client
Of course still much functionality to be implemented.
Work in (slow) progress
Thankfully not that difficult (now)
Basic communication is completed
A few more to come in order to have it as a finished project
Specification of what is needed for any interested user

Introduction
CryoBLMs – Solid State (Si, CVD Diamond) detectors as BLMs placed inside the magnets in cryogenic temperatures
Irradiation tests so as to measure the performance of the detectors

+ K6430 for
Trigger from TTL accelerator timing
4 Si pad detectors
2 CVD pad diamonds
Also [Ioffe]
QMBox DAQ system
Internal Trigger setting

Analysis Process
A] Cleaning of the data
Trigger Level 0
Basic checks and sorting of data
Sum, Max Value, Mean, Mean of first 10 or last 10 values
Many (way too many) unwanted “triggers” that need to be removed
Voltage scan data separated
B] Integrated charge extraction from cleaned data
C] Beam data treatment
Extraction of Gaussian fit of beam from BPM and Beam Intensity data
BPMs – Mean and Deviation of gaussians in both axes
Intensity – Volume under the 3D Gaussian
Sync of BPM / SEC spills
Extraction of dose to the detectors
Double integration of the 3D Gaussian
D] Sync & Normalize !

This script takes care of the conversion from raw BPM data to Gaussian fits.
+ Usage
python bpm1_fit.py -i <input file>
-- More optional parameters:
-o <file name> # output to file.
-s <start date> # specify start date (%d/%m/%Y %H:%M:%S).

Conclusions
Work in progress, as previously mentioned
Data are never perfect, there is always something to go wrong
Loss of sync e.g.
