Python Iseg HV controller

The Iseg HV modules are using Mpod crate. A Mpod-C (controller) is used to control the HV module.

The Mpod-C can be controlled via ethernet, USB, or CAN. For the ethernet, it requires an IP.

GUI control and monitor

The GUI also push monitor values to database and display on Grafana https://fsunuc.physics.fsu.edu/grafana/d/JG7ADC67z/iseg-hv-monitor?orgId=1&refresh=5s

Iseg HV with Wiener Mpod

to control the Mpod-C via USB (say, setting up the IP), in Windows, install the MUSEController.

SNMP

More detail can be found in here.

In linux, install snmp

sudo apt install snmp snmp-mibs-downloader

copy the WIENER-CRATE-MIB.txt into /usr/share/snmp/mibs/

Name	Type	Unit	Read/Write	Comment
outputVoltage	Float	V	R/W	Set voltage
outputCurrent	Float	A	R/W	Set trip current
outputMeasurementSenseVoltage	Float	V	R	Sense output voltage
outputMeasurementCurrent	Float	A	R	Leakage current
outputSwitch	Integer		R/W	0 = off, 1 = on, 2 = reset Emergency Off, 3 = set emergenct Off, 10 = clear events
outputVoltageRiseRate	Float	V/s	R/W
outputVoltageFallRate	Float	V/s	R/W

example syntax

~>snmpget -v 2c -Op .12 -m +WIENER-CRATE-MIB -c guru 128.186.111.101 outputMeasurementSenseVoltage.u1
WIENER-CRATE-MIB::outputMeasurementSenseVoltage.u1 = Opaque: Float: 0.000000000000 V

~>snmpset -v 2c -Op .12 -m +WIENER-CRATE-MIB -c guru 128.186.111.101 outputVoltage.u0 F 0.0
WIENER-CRATE-MIB::outputVoltage.u0 = Opaque: Float: 0.000000000000 V

Python GUI for control and monitor

https://fsunuc.physics.fsu.edu/git/rtang/IsegSNMPGUI

This program should be suitable for all Iseg HV modules using Mpod-C with SNMP protocal.

The only hard-coded thing is the Mpod-C IP, and the database IP and name.
