Error codes

The output pin [ErrCode] indicates the error code that occurred at the last read access of the function block to the BACnet object.

[ErrCode] can test the control program in the Programming editor online mode. In normal mode, [ErrCode] can be used by the program for specific troubleshooting exceptions, e.g., above range, below range.

[ErrCode] = 0 indicates no fault.
[ErrCode] > 0 indicates a fault.

ErrCode < 20 and >= 256

Error codes with a value < 20 and >= 256 are derived from the evaluation of the reliability property of the BACnet object. The error codes may indicate problems with field devices.

ErrCode >= 20 and < 256

Error codes >= 20 und < 256 indicate a problem between function and BACnet object (data point), e.g., difficulties accessing the object and/or required properties. Function blocks and/or data point configuration values may be incorrectly set.

Error codes derived from reliability property

Error code	Definition	Description
0	No fault	N/A
1	No sensor connected	No sensor connected to the input object.
2	Over range	The sensor connected to the input object reads a value over the normal operating range.
3	Under range	The sensor connected to the input object reads a value under the normal operating range.
4	Line break	The connection between the BACnet object and field device indicates a value with a transmission interrupt.
5	Short circuit	The connection between the BACnet object and field device indicates a value with a short circuit.
6	No field device connected	No device connected to the output object.
7	Unknown cause of fault	The automation station reports that the present value is unreliable, but no other error code describes the type of problem.
8	Processing error	Process error occurred.
9	Present value defined as fault	The present value of the multistate object corresponds to one of the states in the property for fault values, but no other fault was found.
10	Configuration error	BACnet object properties are inconsistent.
11	<reserved>	N/A
12	Communication failure	The proper operation of the object depends on communication with a remote sensor or remote device or communication with the remote sensor or remote device was interrupted.
256	Loss of remote communication	N/A
257	Group members missing or not assigned	N/A
258	Device: General fault	N/A
259	General output failure	N/A
260	Electrical protection: Power off	N/A
261	Thermal shutdown	N/A
262	Battery_Fault	N/A
263	Defective luminaire	N/A
264	Incorrect luminaire type	N/A
265	Power supply outside range	N/A
266	Lamp ignition failure	N/A
267	Load voltage outside range	N/A
268	Lamp cycle fault	N/A
269	Thermal overload	N/A
270	Load deviation detected	N/A
271	Electrical overload	N/A
272	Calibration error	N/A
273	Output control limited	N/A
274	Configuration error in I/O extension	N/A
275	Activation failure	N/A
276	Erroneous restart	N/A
300	<Unused>	N/A

Error codes derived from function block error message or return value from the system function chart (SFC)

Error code	Definition	Description
20	Object not accessible	The referenced BACnet object was not found or cannot be accessed.
21	Missing match of object types	The referenced BACnet object type does not match the type supported or expected by the function block. Cause: Present value of BACnet target object is not accessible. Present value of the BACnet target object does not match the data type expected by the function block.
22	Object reference is resolved	If supported, error code 22 indicates the following: Temporary state, BACnet object referenced by the BACnet object reference is not accessible. VAR OUTPUT cannot be determined during the resolution. If the resolution time exceeds a timeout, the error transitions to "ErrCode 20: Object not accessible".
23	Invalid object-reference	No BACnet object references are set.
24	Object is not updated	The BACnet object is in the start phase, e.g., after switch-on or download. In the start phase, the BACnet object was not yet updated by data acquisition.
25	Property not accessible	The property cannot be accessed or the BACnet property data type does not match the property data types supported by the function block.
26	No valid, present value found	The function block "Read-Multiple" could not find a valid, present value property from member objects that were aggregated by the gather type view node object.
27	<reserved>	N/A
28	Configuration parameter out of range	BACnet properties ID or array index value outside range.
29	Evaluation function is not supported	The function block does not support the configured EvlFnct.
30	Internal error	Internal error or system function chart (SFC) error. These are errors that cause an interruption of the SFC query. Typical support requests.
31	Unknown group data tag	The group data tag to be commanded is not known in the firmware.
32	Group data list error	The group data list for commanding is faulty. Distribution of the list is cancelled.
33	Group member overflow	The gathered number of group members exceed the maximum number as supported by the function block.
40	No property defined	No property was defined for the referenced BACnet object.
41	Properties do not match	The properties in the referenced BACnet object do not match the function block properties. Incorrect configuration.

Troubleshooting

If the error code indicates a problem with the device ID or object ID of the function block, ensure that the referenced BACnet object is compatible with the function block.

Function block access to the gather view nodes object:

The object ID displays a gather view node object (must be the same device).
The referenced BACnet object must be compatible with the function block type.
