Definition
The Master generates a negative service response with
this ErrorType if a communication error occurred during a
read or write service, for example the SDCI connection is
interrupted.
The Master generates a negative service response with
this ErrorType, if a Read or Write service is pending lon-
ger than the specified I-Service timeout in the Master.
If the Master received an Event with the EventQualifier
and the EventCode 0x5600, a negative service response
indicating a service timeout is generated and returned to
the requester (Master – ISDU timeout).
If the Master received an Event with the EventQualifier
and the EventCode 0x5800, a negative service response
indicating a service timeout is generated and returned to
the requester (Master – ISDU timeout).
The Master generates a negative service response with
this ErrorType, if its data link layer detects an ISDU
checksum error.
The Master generates a negative service response with
this ErrorType, if its data link layer detects an ISDU ille-
gal service primitive.
If the Master received an Event with the EventQualifier
and the EventCode 0x5200, a negative service response
indicating a parameter length overrun is generated and
returned to the requester (see parameter length overrun)
Events from legacy Devices shall be redirected in com-
patibility mode to this derived ErrorType
