Configuration (continued)
4.12 Diagnosis
The diagnostics telegram has several parts. The first 6
bytes have a fixed meaning. Following may be one or more
diagnostics blocks, each three bytes in length. A
Diagnostics Block is appended for each error.
Byte Bit Name Type Remarks
0
0 Station_Non_Existent Bool Slave does not exist
1 Station_Not_Ready Bool Slave is not reach for data exchange
2 Cfg_Fault Bool Configuration data do not agree
3 Ext_Diag Bool Slave provides expanded diagnostics
4 Not_Supported Bool Slave does not support diagnostics
5 Invalid_Slave_Response Bool Invalid slave response (sets slave to 0)
6 Prm_Fault Bool Wrong parameterization received
7 Master_Lock Bool Slave was parameterized by a different master 1
1
0 Prm_Req Bool Slave must be re-parameterized
