APS Sub-Layer Status Parameters

Application support (APS) sub-layer confirm primitives often include a parameter that reports on the status of the request to which the confirmation applies:

• A request has been executed successfully
• A transmit request failed since the ASDU is too large and fragmentation is not supported
• A received fragmented frame could not be defragmented at the current time
• A received fragmented frame could not be defragmented since the device does not support fragmentation
• A parameter value was out of range
• An APSME-UNBIND.request failed due to the requested binding link not existing in the binding table
• An APSME-REMOVE-GROUP.request has been issued with a group identifier that does not appear in the group table
• A parameter value was invalid or out of range
• An APSDE-DATA.request requesting acknowledged transmission failed due to no acknowledgement being received
• An APSDE-DATA.request with a destination addressing mode set to 0x00 failed due to there being no devices bound to this device
• An APSDE-DATA.request with a destination addressing mode set to 0x03 failed due to no corresponding short address found in the address map table
• An APSDE-DATA.request with a destination addressing mode set to 0x00 failed due to a binding table not being supported on the device
• An ASDU was received that was secured using a link key
• An ASDU was received that was secured using a network key
• An APSDE-DATA.request requesting security has resulted in an error during the corresponding security processing
• An APSME-BIND.request or APSME.ADDGROUP.request issued when the binding or group tables, respectively, were full
• An ASDU was received without any security
• An APSME-GET.request or APSME-SET.request has been issued with an unknown attribute identifier
• Status not indicated
