1.7.2.1.10 Diagnosis
Structure of CI590-CS31-HA Diagnosis Block
If a CI590-CS31-HA module is connected via a CS31 bus, then the field bus master receives
diagnosis information by an extended diagnosis block. The following table specifies the struc-
ture of this information. In case of an error the user can get this information by the diagnosis
system, see

According to the I/O bus specification
Bit 7 and bit 6, coded error class
0 = E1
1 = E2
2 = E3
3 = E4
Bit 0 to bit 5, coded error description
passed on by modules to the fieldbus master
7 CI590-CS31-HA diag-
nosis byte, flags
According to the I/O bus specification
Bit 7: 1 = coming error
Bit 6: 1 = leaving error
Bit 5: 1 = diag reset
Bit 2 to bit 4: reserved
Bit 1: 1 = explicit acknowledgement
Bit 0: 1 = static error
passed on by modules to the fieldbus master
Value = 0: static message for other systems,
which do not have a coming/leaving evaluation
