Error Code List

Error Codes

This page lists all error codes with more in-depth descriptions than can be found in the Phidget22 API.

These codes are thrown as Phidget Exceptions or returned as error codes from C functions. See the Phidget22 API documentation for your device to see which error codes are supported. The error codes are generic, and the error description may contain more detailed information about the actual cause of the error.

Name	Value	Description	Details
OK	Hex: 0x00 Dec: 0	Success
PERM	Hex: 0x01 Dec: 1	Not Permitted
NOENT	Hex: 0x02 Dec: 2	No Such Entity
TIMEOUT	Hex: 0x03 Dec: 3	Timed Out	This can happen for a number of common reasons: Check that the Phidget you are trying to open is plugged in, and that the addressing parameters have been specified correctly. Check that the Phidget is not already open in another program, such as the Phidget Control Panel, or another program you are developing. If your Phidget has a plug or terminal block for external power, ensure it is plugged in and powered. If you are using remote Phidgets, ensure that your computer can access the remote Phidgets using the Phidget Control Panel. If you are using remote Phidgets, ensure you have enabled Server Discovery or added the server corresponding to the Phidget you are trying to open. If you are using Network Server Discovery, try extending the timeout to allow more time for the server to be discovered.
KEEPALIVE	Hex: 0x3A Dec: 58	Keep Alive Failure
INTERRUPTED	0Hex: 0x04 Dec: 4	Op Interrupted

FAULT	Hex: 0x08 Dec: 8	Address Issue
BUSY	Hex: 0x09 Dec: 9	Resource Busy	The Phidget you are trying to open is already open elsewhere. Check that the Phidget is not already open in another program, such as the Phidget Control Panel, or another program you are developing. Check that the addressing parameters have been specified correctly.
EXIST	Hex: 0x0a Dec: 10	Object Exists
NOTDIR	Hex: 0x0b Dec: 11	Object is not a directory
ISDIR	Hex: 0x0c Dec: 12	Object is a directory

RO	Hex: 0x13 Dec: 19	Read Only Object
UNSUPPORTED	Hex: 0x14 Dec: 20	Operation Not Supported	This error is thrown when a method is called that is not supported by the Phidget hardware. For example, calling setFanMode on the 1065, which has no fan. Or calling setEnabled on an encoder channel that is always enabled, like the one built in to the DCC1002.
INVALIDARG	Hex: 0x15 Dec: 21	Invalid Argument	One or more of the parameters passed to the function is not accepted by the channel in its current configuration. This may also be an indication that a NULL pointer was passed where a valid pointer is required.
AGAIN	Hex: 0x16 Dec: 22	Try again
NOTEMPTY	Hex: 0x1a Dec: 26	Not Empty
UNEXPECTED	Hex: 0x1c Dec: 28	Unexpected Error
DUPLICATE	Hex: 0x1b Dec: 27	Duplicate
BADPASSWORD	Hex: 0x25 Dec: 37	Bad Credential

PIPE	Hex: 0x29 Dec: 41	Broken Pipe
RESOLV	Hex: 0x2c Dec: 44	Name Resolution Failure
UNKNOWNVAL	Hex: 0x33 Dec: 51	Unknown or Invalid Value
NOTATTACHED	Hex: 0x34 Dec: 52	Device not Attached	This can happen for a number of common reasons: Be sure you are opening the channel before trying to use it. If you are opening the channel, the program may not be waiting for the channel to be attached. If possible use openWaitForAttachment. Otherwise, be sure to check the Attached property of the channel before trying to use it.
INVALIDPACKET	Hex: 0x35 Dec: 53	Invalid or Unexpected Packet
2BIG	Hex: 0x36 Dec: 54	Argument List Too Long
BADVERSION	Hex: 0x37 Dec: 55	Bad Version	This error occurs when the version of the Phidget libraries is different than the one being used on the network server. Update both to the latest version to solve the error. If you're using Javascript, ensure that the same version of phidget22.min.js is being used in your working directory as the one being pointed to by the webserver in the Phidget Control Panel.
CLOSED	Hex: 0x38 Dec: 56	Closed
NOTCONFIGURED	Hex: 0x39 Dec: 57	Not Configured
