wiener_hv

An object-oriented python wrapper for sending SNMP commands to Wiener high voltage modules.

Requirements

• python (currently only tested on python2, migration to python3 in-progress)
• WIENER-CRATE-MIB.mib file installed in either local directory or /usr/local/share/snmp/mibs/

Operation

The highVoltage class contains methods for applying voltages to individual channels or the whole board. Voltages can be read from or outputted to text files.

from highVoltage import highVoltage
hv = highVoltage('10.10.0.1')    # input correct IP address here

# read values from file named HVDefaults.txt
channelArr, voltageArr = hv.voltageFromFile("HVDefaults.txt")

# apply values to boards
hv.setVoltages(channelArr, voltageArr)

# check voltages and print them to terminal
hv.checkVoltages()

Command-line operation

The script can also be called from the command line with three arguments: on, off, and status.

python highVoltage.py on This will pull voltages from the default file (LastUsedHVSettings.txt) and apply them to the boards.

python highVoltage.py off This will shutdown all channels of the crate

python highVoltage.py status This will print to screen the channels with their read-out voltage and current.
