Daemon for the Newport connex-agp controllers This daemon was specifically tested with the CONEX-AG-PR100P. It should, in theory, work (though with other units, potentially) for other CONEX line controllers.

installation

The newport-connex-agp daemon can be installed using the following package managers:

PyPI

traits

The newport-connex-agp daemon is composed of the following traits:

has-limits
has-position (from has-limits)
is-homeable
uses-uart
uses-serial (from uses-uart)
is-daemon

hardware

The newport-connex-agp daemon has been tested with the following hardware:

conex-ag-pr100p

configuration

axis (Integer) default: 1
Allows for daisy chained controllers

units (String) default: deg
Units for the motor attatched to the controller

limits ([number, number]) default: [-inf, +inf]
Configuration limits are strictly optional.
from has-limits

out_of_limits (string) default: closest
Control behavior of daemon when set_position is given a value outside of limits.
from has-limits

serial_port (string)
from uses-uart

baud_rate (number)
from uses-uart

port (integer)
TCP port for daemon to occupy.
from is-daemon

serial (string) default: NULL
Serial number for the particular device represented by the daemon
from is-daemon

make (String) default: NULL
from is-daemon

model (String) default: NULL
from is-daemon

state

The newport-connex-agp daemon will provide the following state information:

status
type: String
Device status, translated into text from the Tell Status (TS) command.

error_code
type: String
Four digit code describing error conditions in the Tell Status (TS) command.

hw_limits
type: [number, number]
from has-limits

position
type: number
from has-limitshas-position

destination
type: number
from has-limitshas-position

methods

Daemons with the newport-connex-agp trait expose the following public methods:

get_limits ➜ [number, number]
Get daemon limits. Limits will be the intersection of config limits and driver limits (when appliciable).
from has-limits

in_limits ➜ boolean
Check if a given position is within daemon limits.
from has-limits
Arguments:

position, {'type': 'number'}

get_destination ➜ number
Get current daemon destination.
from has-limitshas-position

get_units ➜ string
Get units of daemon. These units apply to the position and destination fields.
from has-limitshas-position

get_position ➜ number
Get current daemon position.
from has-limitshas-position

set_position
Give the daemon a new destination, and begin motion towards that destination.
from has-limitshas-position
Arguments:

position, {'type': 'number'}

set_relative ➜ number
Give the daemon a new destination relative to its current position. Daemon will immediately begin motion towards new destination. Returns new destination.
from has-limitshas-position
Arguments:

distance, {'type': 'number'}

home
Initiates the homing procedure. The daemon will report as busy during the homing procedure. After the homing procedure is complete, the daemon will return to the current destination.
from is-homeable

direct_serial_write
Expose direct access to the serial port to clients. This should not be encouraged for normal use, but may be very important for debugging. If a device is expected to return data, it should be logged at the INFO level, not returned to the client. This is done to allow long tasks to be run asynchronously, and to explicitly discourage use of this method except when debugging. Setting `busy` to true is encouraged, but individual daemon writers should consider their own use case.
from uses-uartuses-serial
Arguments:

message, {'type': 'string'}

busy ➜ boolean
Returns true if daemon is currently busy.
from is-daemon

id ➜ dictionary
JSON object with information to identify the daemon, including name, kind, make, model, serial.
from is-daemon

get_config_filepath ➜ string
String representing the absolute filepath of the configuration file on the host machine.
from is-daemon

get_config ➜ dictionary
Full configuration for the individual daemon as defined in the TOML file. This includes defaults and shared settings not directly specified in the daemon-specific TOML table.
from is-daemon

get_traits ➜ [string]
Get a full list of the daemon traits.
from is-daemon

get_state ➜ dictionary
Get daemon state, as saved in the state.toml file.
from is-daemon

set_state
Set daemon state. Accepts any subset of the state dictionary, dynamically.
from is-daemon

list_methods ➜ [string]
Get an array of all known public method names.
from is-daemon

shutdown
Cleanly shutdown (or restart) daemon.
from is-daemon
Arguments:

restart, {'type': 'boolean', 'default': False}

help ➜ string
If method not given, return a human-readable string with information about the daemon as a whole. If method is given, return a human-readable string with the signature of the method on the first line and a description of the method on subsequent lines. The signature is not specified to be in any particular language. It is intended for usage by humans ONLY.
from is-daemon
Arguments:

method, {'type': 'string'}
