Diagnostics and error handling

BK3xx068 Version: 4.3.0

Errors when checking the CfgData

Error code 2

Error code 2 indicates that a byte in the CfgData is not correct. The error argument describes which CfgData

byte has been detected as containing an error (the offset of the faulty byte +1).

Error code 5

Error code 5 indicates that the length of the digital outputs (in bytes) calculated from the CfgData is not

correct. The error argument contains the expected byte length.

Error code 6

Error code 6 indicates that the length of the digital inputs (in bytes) calculated from the CfgData is not

correct. The error argument contains the expected byte length.

Error code 7

Error code 7 indicates a variety of errors when checking the CfgData. The error argument describes the

error.

Error argument Description

1 The length of the CfgData received is not correct

2 The syntax of the CfgData received is not correct

3 The length of the DP input data that has been calculated from the CfgData is too large

4 The length of the DP output data that has been calculated from the CfgData is too large

5..12 Reserve

13 Maximum input length exceeded

14 Maximum output length exceeded

15 Maximum diagnostic data length exceeded (64bytes) or value below minimum

diagnostic data length (16bytes)

16 Maximum config data length exceeded (240bytes) or value below minimum config data

length (1byte)

17 Maximum parameter data length exceeded (224bytes) or value below minimum

parameter data length (64bytes)

Errors during slave start-up

Error code 8

Error code 8 indicates that the length of the DP buffer is greater than the size of the DP RAM in the

PROFIBUS ASIC. The error argument contains the difference (divided by 8). DP communication is

deactivated.

Error code 9

Error code 9 indicates a variety of errors that may be detected as the device boots. The error argument

describes the error.

Error argument Description

1 The length of the DP input data is too great (too many modules are inserted)

2 The length of the DP output data is too great (too many modules are inserted)

3 The length of the CfgData is too great (too many modules are inserted)
