Tools (7)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • apply_safe_state

    Emergency action: write the scientist-configured safe-state PVs (--option safe_state, e.g. motor STOP fields, shutter close, HV off), all of them even if one fails. Available in read-only mode. It does not replace the facility's own interlocks and stop buttons.

  • get_pv

    Read one PV with its metadata: value, units, precision, alarm severity/status, IOC timestamp and age, display/alarm/warning/control limits and enum state names. Waveforms come back downsampled with min/max/mean statistics.

  • get_pvs

    Read many PVs at once (e.g. all motors or vacuum gauges of a beamline). PVs that cannot be reached are listed in `errors` instead of failing the whole call.

  • monitor_pv

    Subscribe to a PV and collect every value change for `duration_s` seconds (or until `max_updates`), then return statistics (min/max/mean/std, drift rate) and the updates.

  • put_pv

    Write a PV. This can move motors, open shutters, change magnet or high-voltage setpoints and heat or cool samples: tell the user exactly what will change first. The write is refused unless the PV matches the put allow-list, the IOC grants write access, and the value has the right type and lies within the PV's control limits (DRVL/DRVH). Returns the read-back value.

  • put_pvs

    Write several PVs in order (e.g. set both slit blades). Every write is validated first (allow- list, access rights, type, control limits); if any is invalid nothing is written. Writing stops at the first failure and the rest are reported as not written. The whole batch must finish within an hour: writes that would start later are not sent.

  • pv_info

    Connection details of a PV: serving IOC host:port, native type, element count, and whether this client has read/write access (EPICS access security) and passes the put allow-list.
