Goals

• New acquisition and visualisation of Dafne temperature probes.

Background and strategic fit

We want to acquire PT100 probes + xx, we want to use EPICS as base control system to acquire modbus ICPDAS interface ICPDAS ET7xx. Show historical data using Grafana dashboard.

HW

List and information of acquisition modules are available at Asset Management.

• 12 ICP modules ET-7215 for "PT100" thermoresistors;
• 1  ICP module ET-7218Z/S for the two "T" thermocouples close to the IR region)

Probe List

Insert here the information about the Element Name of the probe, the installation Zone, Probe type (i.e PT100),the ICPDAS IP that acquires the probe, the Analog Input the number of (1:7) connected to  the probe, the switch IP and port connected to the ICPDAS that acquire the probe.

How to add sensors

Sensors must be added to file epics-archiver-on-dafne/iocsh-icpdas/dafne-icpdas.cmd.

The configuration is self-explanatory, please pay attention to change the name accordingly when cut and paste.

Add sensor to Epics Config

ssh dante@vldanteco101
cd epics-archiver-on-dafne
cd iocsh-icpdas
gedit dafne-icpdas.cmd

Once finished as root restart the docker compose that contains an IOC that reads ICPDAS , the epics archiver and a CU that reads the IOC:

systemctl start dafne-epics
# and check 
systemctl status dafne-epics

To check if a PV( i.e. DAFNE:ICP-23-0001:Temp_TRAES104) is correctly added you can attach to the running epics container  through:

ssh dante@vldanteco101
docker exec -it epics bash
root@367907cf46e3:/mnt/data/iocsh-icpdas# caget DAFNE:ICP-23-0001:Temp_TRAES104
DAFNE:ICP-23-0001:Temp_TRAES104 20.5366

Add sensor to !CHAOS Config

Open Chaos Dashboard node configuration, edit DAFNE/MAINRING/TEMP/ALL and add new PVs.

The add the PV in driver parameters:

Restart the CU DAFNE/MAINRING/TEMP/ALL

Git commit changes

ssh dante@vldanteco101
cd epics-archiver-on-dafne
cd iocsh-icpdas
git commit -m "my comment" .
git push origin

Add PV to Epics Archiver

Open Epics Archiver

Add the new PV(s) in the text box, then check and archive.
