CIP General Status Codes
(Original Document)
NOTE: Taken by permission from The CIP Networks Library, Volume 1, Common Industrial Protocol (CIP™), Edition 3.6, April 2009.
The following table lists the status codes that may be present in the general status code field of a detected error response message. Note that the extended code field is available for use in further describing any general status code. Extended status codes are unique to each general status code within each object. Each object manages the extended status values and value ranges (including vendor specific). All extended status values are reserved unless otherwise indicated within the object definition.
General Status Code (in hex)
Status Name
Description of Status
00
Success
Service was successfully performed by the object specified.
01
Connection unsuccessful
A connection related service was unsuccessful along the connection path.
02
Resource unavailable
Resources needed for the object to perform the requested service were unavailable.
03
Invalid parameter value
See status code 0x20, which is the preferred value to use for this condition.
04
Path segment error
The path segment identifier or the segment syntax was not understood by the processing node. Path processing stops when a path segment error is detected.
05
Path destination unknown
The path is referencing an object class, instance, or structure element that is not known or is not contained in the processing node. Path processing stops when a path destination unknown error is detected.
06
Partial transfer
Only part of the expected data was transferred.
07
Connection lost
The messaging connection was lost.
08
Service not supported
The requested service was not implemented or was not defined for this object class/instance.
09
Invalid attribute value
Invalid attribute data detected.
0A
Attribute list error
An attribute in the Get_Attribute_List or Set_Attribute_List response has a non-zero status.
0B
Already in requested mode/state
The object is already in the mode/state being requested by the service.
0C
Object state conflict
The object cannot perform the requested service in its current mode/state.
0D
Object already exists
The requested instance of object to be created already exists.
0E
Attribute not settable
A request to modify a non-modifiable attribute was received.
0F
Privilege violation
A permission/privilege check was unsuccessful.
10
Device state conflict
The device’s current mode/state prohibits the execution of the requested service.
11
Reply data too large
The data to be transmitted in the response buffer is larger than the allocated response buffer.
12
Fragmentation of a primitive value
The service specified an operation that is going to fragment a primitive data value, i.e., half a REAL data type.
13
Not enough data
The service did not supply enough data to perform the specified operation.
14
Attribute not supported
The attribute specified in the request is not supported.
15
Too much data
The service supplied more data than was expected.
16
Object does not exist
The object specified does not exist in the device.
17
Service fragmentation sequence not in progress
The fragmentation sequence for this service is not currently active for this data.
18
No stored attribute data
The attribute data of this object was not saved prior to the requested service.
19
Store operation unsuccessful
The attribute data of this object was not saved due to an unsuccessful attempt.
1A
Routing unsuccessful, request packet too large
The service request package was too large for transmission on a network in the path to the destination. The routing device was forced to abort the service.
1B
Routing unsuccessful, response packet too large
The service response packet was too large for transmission on a network in the path from the destination. The routing device was forced to abort the service.
1C
Missing attribute list entry data
The service did not supply an attribute in a list of attributes that was needed by the service to perform the requested behavior.
1D
Invalid attribute value list
The service is returning the list of attributes supplied with status information for those attributes that were invalid.
1E
Embedded service error
An embedded service resulted in a detected error.
1F
Vendor specific error
A vendor specific error has been detected. The additional code field of the error response defines the particular error encountered. Use this general code only when none of the codes presented in this table or within an object class definition accurately reflect the detected error.
20
Invalid parameter
A parameter associated with the request was invalid. This code is used when a parameter does not meet the requirements of this specification and/or the requirements defined in an application object specification.
21
Write-once value or medium already written
An attempt was made to write to a write-once medium (e.g., WORM drive, PROM) that has already been written, or to modify a value that cannot be changed once established.
22
Invalid reply received
An invalid reply is received (e.g., reply service code does not match the request service code, or reply message is shorter than the minimum expected reply size). This status code an serve for other causes of invalid replies.
23
Buffer overflow
The message received is larger than the receiving buffer can handle. The entire message was discarded.
24
Message format error
The format of the received message is not supported by the server.
25
Key failure in path
The key segment that was included as the first segment in the path does not match the destination module. The object specific status indicates which part of the key check was unsuccessful.
26
Path size invalid
The size of the path that was sent with the service request is either not large enough to allow the request to be routed to an object or too much routing data was included.
27
Unexpected attribute in list
An attempt was made to set an attribute that is not able to be set at this time.
28
Invalid member ID
The member ID specified in the request does not exist in the specified class/instance/attribute.
29
Member not settable
A request to modify a non-modifiable member was received.
2A
Group 2 only server — general error
This detected error code may only be reported by DeviceNet group 2 only servers with 4 Kb or less code space and only in place of service not supported, attribute not support, or attribute not settable.
2B
Unknown Modbus error
A CIP to Modbus translator received an unknown Modbus exception code.
2C
Attribute not gettable
A request to read a non-readable attribute was received.
2D - CF
Reserved by CIP for future extensions.
D0 - FF
Reserved for object class and service errors
This range of detected error codes is used to indicate object class specific detected errors. Use this range only when none of the codes presented in this table accurately reflect the error that is detected.
