MaxiGaugeTPG366 Satellite

Name	MaxiGaugeTPG366
Description	Satellite for the MaxiGaugeTPG366 pressure sensor
Language	Python
Category	Environment Sensors
Website	madmax/hamburg/maxigaugetpg366-satellite

Description

Constellation satellite to read pressures from a MaxiGauge TPG366 device.

Note

This satellite requires write access to the serial port or USB-to-serial converter the device is attached to. It is recommended to not run this satellite with root privileges but to allow the regular user access to the required port instead. On Unix, if the port is e.g. /dev/ttyUSB0, the group can be found via stat /dev/ttyUSB0 (the Gid entry). If the group is e.g. dialout, the permissions can be given with sudo usermod -a -G dialout $USER. A restart is required for the changes to be effective.

Parameters

Configuration	Description	Type	Default Value
port	Path to serial device, e.g. /dev/ttyUSB0	String
unit	Possible values are: 0: mbar/bar, 1: Torr, 2: Pascal, 3: Micron, 4: hPascal, 5: Volt	Integer	4
channel_names	Names of the recorded metrics	List	["PRESSURE1", "PRESSURE2", "PRESSURE3", "PRESSURE4", "PRESSURE5", "PRESSURE6"]
sampling_interval	Sampling interval in seconds	Integer	10

Metrics

Metric	Description	Value Type	Metric Type	Interval
PRESSURE1-6	Pressure channels, names and unit are read from configuration (see above). Special values: -1 - Underrange, -2 Overrange, -3: Error	Float	LAST_VALUE	configurable

Framework Parameters

This satellite inherits the following framework parameters from its base classes:

Parameters inherited from Satellite

Autonomous Operation

Parameter	Type	Description	Default Value
_max_heartbeat_interval	Unsigned integer	Maximum interval in seconds between heartbeats to be sent to other Constellation components. The time between heartbeat is adjusted automatically according to the number of nodes in the Constellation but will never exceed this value.	30
_role	Role name	Role this satellite should take in the Constellation. Accepted values are ESSENTIAL, DYNAMIC, TRANSIENT and NONE.	DYNAMIC

Transition Orchestration

Parameters to control autonomous transition orchestration of satellites:

Parameter	Type	Description	Default Value
_conditional_transition_timeout	Unsigned integer	Timeout in seconds to wait for all conditions to be satisfied for conditional transitioning	30
_require_initializing_after	List of strings	List of canonical names of remote satellites for conditional transitioning in initializing state	-
_require_launching_after	List of strings	List of canonical names of remote satellites for conditional transitioning in launching state	-
_require_landing_after	List of strings	List of canonical names of remote satellites for conditional transitioning in landing state	-
_require_starting_after	List of strings	List of canonical names of remote satellites for conditional transitioning in starting state	-
_require_stopping_after	List of strings	List of canonical names of remote satellites for conditional transitioning in stopping state	-
