prod

Switch power to lab equipment from the command line. Supported hardware:

• ANEL NET-CONTROL / NET-PwrCtrl, network controlled relays
• Rohde & Schwarz NGE100 series power supplies, over VISA

$ prod
PORT                            STATE
ac
1 "tact1"                       on
...
$ prod tact1 cycle

Usage is prod [DEVICE/PORT|ALIAS] [show|on|off|toggle|cycle|pulse]. Without arguments, prod lists all ports and their state. Without an operation, it shows the state of the given port. cycle switches off, waits one second and switches on again, pulse does the opposite.

Configuration

prod reads the first of ~/.prod.yaml, ~/.config/prod.yaml and /etc/prod.yaml:

devices:
  ac:
    compatible: anel,net-control
    url: http://192.168.0.244
    auth: adminanel             # user and password, the default
    ports:
      1:
      2:

  psu:
    compatible: rs,nge100
    resource: TCPIP::192.168.0.10::INSTR
    ports:
      1:
        voltage: 12
        current: 2

aliases:
  tact1: ac/1
  tact2: ac/2

Dependencies

On Debian and Ubuntu:

sudo apt install python3-argcomplete python3-yaml

The NGE100 also needs python3-pyvisa and a VISA backend, such as python3-pyvisa-py. Installing with make needs python3-pip and python3-setuptools.

Installing

sudo make install

This installs prod with pip under /usr/local, and its bash completion in /usr/local/share/bash-completion/completions. The completion is active in new shells. Remove it all with sudo make uninstall.

To install in a virtual environment of its own instead, with the Python dependencies from PyPI as listed in pyproject.toml:

pipx install .              # or '.[nge100]' for the NGE100
cp prod.bash ~/.local/share/bash-completion/completions/prod
