Error frames data set
If a data set is rejected by the COM190, the following happens:
• The request is negatively acknowledged with an NRS frame.
• The request is signaled to the master with an error frame that includes the negative
acknowledgment and error code.
Structure of the error frame
The error frame has the following structure:
Function_Num
• Function_Num
If no error: B#16#00
For an error:
– Function identification from data set (DS) record: reading 0xDE, writing 0xDF
– DS record protocol element not used: B#16#C0
• Error_Decode
Location of error identification: COM190 0x80
• Error_Code_1
Error identification
Error_Code_1 and its cause:
• Error_Code_2
Manufacturer-specific extension of error identification: COM190 0x00, not used.
Note
The error frame structure used and the error codes are based on the SIMATIC error
messages.

Error_Decode
Code Cause
0xA0 Read error (data set currently not readable, e.g. because required (IOM) function is not
available)
0xA1 Write error (on write access to a "read-only" DSx and general error on write access)
0xA7 Busy on write/read request:
The COM190 is busy with another request. The request must be repeated.
0xA9 Function is not supported (on write access for I&M0 data)
0xB0 Invalid index (for non-implemented DSx) and read error (on read access to a write-only
DSx)
0xB1 Write/read (IM data) length error (on incorrect length data for write DSx)
0xB2 Invalid slot (when an invalid slot is specified for read and write DSx)
0xB6 Access denied (e.g. due to write protection and invalid slot for writing IM1 ... 4)
0xB7 Invalid Parameter (request contains invalid parameter, complete request was rejected)
0xBA User Defined – Write Partial (request contains inadmissible commands, request is partial-
ly executed)
0xC4 Internal error: Request processing has failed.
