Example: Diagnostics information of Servo Drives 9400 in ’EXTENDEDINFO’
EXTENDEDINFO
ARRAY [0...129]
OF BYTE
Contains the slave-specific diagnostics information.
Byte 0 Station status 1
Byte 1 Station status 2
Byte 2 Station status 3
Byte 3 Master station number
Byte 4 Manufacturer's identification mark (high byte)
Byte 5 Manufacturer's identification mark (low byte)
Byte 6 ... n Slave-specific diagnostics information (see documentation of the
slave)
Byte in
EXTENDEDINFO
Meaning
6 Bit 0: Station does not exist (set by the master).
Bit 1: Slave is not ready for data exchange.
Bit 2: Configuration data do not match each other.
Bit 3: Slave has extended diagnostic data.
Bit 4: Requested service is not supported by the slave.
Bit 5: Slave response is invalid (set by the master)
Bit 6: Incorrect parameter setting
Bit 7: Slave is parameterised by another master (set by the master).
7 Bit 0: Slave has to be parameterised again.
Bit 1: Static diagnostics
Bit 2: Fixedly set to "1".
Bit 3: Watchdog active
Bit 4: Freeze command received.
Bit 5: Sync command received.
Bit 6: Reserved
Bit 7: Slave is deactivated (set by the master).
8 Bit 7: Diagnostics overflow - amount of diagnostics data present in the slave is too large to fit
into one telegram.
9 Bits 0 ... 7: Master address after parameter setting ("0xFF" without parameterisation)
10 Bits 0 ... 7: ID number (high byte)
11 Bits 0 ... 7: ID number (low byte)
12 Header
• The header contains the block length of extended diagnostics and the header byte.
• In this case, the value of the entry is "0x0A" (bytes 6 ... 15 = 10 bytes).
13 Status_Type
• The value of this entry is fixed. For the following bit assignment it is "0x81":
–Bit 7 = 1: "status"
–Bit 0 = 1: "status message"
–Values of all other bits = 0
14 Slot_Number
• Value of the slot number: "0x00"
15 Specifier
• A detected error is entered in the specifier with the identification "0x0" (status coming).
• An eliminated error is entered in the specifier with the identification "0x02" (status going).
• If no errors are indicated, the entry in the specifier has the value "0x00" (no further
differentiation).
16 PROFIsafe, error number of the safety module
• If an error occurs in the safety module, byte 10 (low byte) and byte 11 (high byte) contain the
corresponding error number.
• More information can be found in the documentation of the corresponding safety module.
