Note

On some devices, the values returned may be dependent on channel configuration

settings.

Some devices require the {ch} format.

SELFCAL

 Get a value indicating if the device supports self-calibration for analog inputs.

Message

"@AI:SELFCAL"

Response

"AI:SELFCAL=<implementation>value"

implementation

PROG% (programmable), or not specified if value is

NOT_SUPPORTED

value

SUPPORTED, NOT_SUPPORTED

Example

"AI:SELFCAL=PROG%SUPPORTED"

SENSORS

 Get the analog input sensor types that are supported by the device or specified channel.

Message

"@AI:SENSORS"

"@AI{ch}:SENSORS"

Response

"AI{ch}:SENSORS=implementation>value"

Channel number (if {ch} format is used).

implementation

FIXED%, PROG% (programmable), HWSEL% (hardware selectable),

or not specified if value is NOT_SUPPORTED

value

TC, RTD, THERM (thermistor), or SEMI (semiconductor), or returns

NOT_SUPPORTED if the device doesn't support analog input sensors

or the value of {ch} is not valid for the device.

Example

"AI{0}:SENSORS=FIXED%TC"

SENSORCONFIG

 Get the analog sensor configurations that are supported by the specified channel.

Message

"@AI{ch}:SENSORCONFIG"

Response

"AI{ch}:SENSORCONFIG=implementation>value"

Channel number.

implementation

FIXED%, PROG% (programmable), HWSEL% (hardware selectable),

or not specified if value is NOT_SUPPORTED

value

2WIRE, 3WIRE, 4WIRE, FULLBRG, HALFBRG, QTRBRG, or returns

NOT_SUPPORTED if the device doesn't support configuration of

sensors or the value of {ch} is not valid for the device.

Example

"AI{0}:SENSORCONFIG=PROG%2WIRE,3WIRE,4WIRE"
