DT measurements

Goals

• New acquisition and visualisation of DT modbus devices

Background and strategic fit

We want to acquire DT modbus devices, we want to use EPICS as base control system to acquire modbus ICPDAS interface. Show historical data using Grafana dashboard.

HW

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

Grafana dashboard

Grafana Dashboard

Dashboard: https://dashboard.lnf.infn.it/prod/grafana/d/aFCo3JX4z/energy?orgId=1&refresh=10s&from=1689673914848&to=1689684714848

directory DT-LNF-INFN

How to add sensors

Sensors must be added to file https://baltig.infn.it/chaos-lnf-control/iocsh-dt-modbusdev/-/blob/main/dt-modbusdev.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

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.
