Table 1-5 Standard Diagnose data
Item Description
STATION STATUS 1
(Size: 1 byte)
The state of a DP-Slave is indicated.
Bit 7: Diag.Master_Lock
This bit indicates that the parameters of the DP-Slave are set by another DP-Master.
When the value of MASTER_ADDRESS is neither 255 nor the address of the DP-
Master, this bit is set by the DP-Master.
Bit 6: Diag.Prm_Fault
This bit is set by the DP-Slave when the latest parameter data contains an error.
Bit 5: Diag.Invalid_Slave_Response
This bit is set by the DP-Master when incorrect data is received from the DP-Slave.
Bit 4: Diag.Not_Supported
This bit is set by the DP-Slave when the DP-Slave receives an instruction that is not
supported by the DP-Slave.
Bit 3: Diag.Ext_Diag
This bit is set by the DP-Slave when extended diagnose data can be used. The DP-
Master of FANUC CNCs can reference up to 26 bytes of the extended diagnose data.
Bit 2: Diag.Cfg_Fault
This bit is set by the DP-Slave when the latest configuration data differs from the data
held by the DP-Slave.
Bit 1: Diag.Station_Not_Ready
This bit is set by the DP-Slave when the DP-Slave is not ready for data transfer.
Bit 0: Diag.Station_Non_Existent
This bit is set by the DP-Slave when communication with the DP-Slave is impossible.
STATION STATUS 2
(Size: 1 byte)
The state of a DP-Slave is indicated.
Bit 7: Diag.Deactivated
This bit is set by the DP-Master when communication with the DP-Slave is disabled
during slave parameter setting.
Bit 6: Reserved (undefined)
Bit 5: Diag.Sync_Mode
This bit is set by the DP-Slave when the Sync control command is received.
Bit 4: Diag.Freeze_Mode
This bit is set by the DP-Slave when the Freeze control command is received.
Bit 3: Diag.WD_On
This bit is set by the DP-Slave when the disconnection detection function is operating.
Bit 2: Reserved (set to 1 at all times)
Bit 1: Diag.Stat_Diag
If this bit is set by the DP-Slave, the DP-Master reads the diagnose data until this bit is
reset.
Bit 0: Diag.Prm_Req
This bit is set by the DP-Slave when the parameters of the DP-Slave need to be set
again. The setting of this bit is held until the parameters are set again.
STATION STATUS 3
(Size: 1 byte)
The state of a DP-Slave is indicated.
Bit 7: Diag.Ext_Diag_Overflow
This bit is set by the DP-Slave when diagnose data cannot be stored in the extended
diagnose data area. The DP-Master of FANUC CNCs can reference up to 26 bytes of the
extended diagnose data.
Bits 6 to 0: Reserved
MASTER ADDRESS
(Size: 1 byte)
The address of the DP-Master that set the parameters of the DP-Slave is set. If the
parameters are not set by the DP-Master, 255 is set.
IDENT NUMBER
(Size: 2 bytes)
The identification number of a DP-Slave is set.
