Variable Name Size/Type Description
Out - SetSlaveAddress 1
Single-Bit
Boolean
This is the bit your control and sequencing logic will use
to trigger a message to tell the PROFIBUS Master to
send a new network node number to a specific slave,
thereby changing its node address. Set this bit to one (1)
whenever no other messages are active and you want to
send this acyclic message.
Out -
CurrentSlaveAddress 1
8-Bit Byte
Valid entries: 0 - 126
Set this variable to the current address of the slave
whose address you wish to change.
Out - NewSlaveAddress 1
8-Bit Byte
Valid entries: 0 - 126
Set this variable to the new address you wish the slave to
have.
Out - NoAddressChange 1
8-Bit Byte
Valid entries:
00h Change of address is still possible at a later stage.
01h - FFh Change or address is not possible until after
slave reset
This parameter specifies whether the slave address can
be changed again at a later stage. if this is not allowed,
then it is only possible to change the address with this
function after initial reset. After the initial reset, the slave
takes the default address 126.
Out - SlaveIdentNumber 1
16-bit Integer
Unique PROFIBUS Slave Identifier, assigned by
PROFIBUS User Organization
Out - TimeOut 1
16-bit Integer
Used to hold the amount of time in milliseconds to wait
for a response to the Modbus TCP/IP command before
assuming a communication error has occurred and
setting the In-MessageError status bit
Out - MailBoxData Multi-variable
nested DDT For details, see Modbus DDT (page 98)
In - Error1 1
8-bit Byte
Error Byte 1 of 4. Bytes 2 - 4 are reserved
For details on Error Byte 1, see Acyclic Message Status
Word (page 218)
In - Length 1
8-bit Byte
Range 6 to 244
Number of bytes sent by the slave as response data, if
any.
In - ReturnCode 1
16-bit Integer
Refer to Return Codes (page 219) for additional
information.
In - Fault 1
16-bit Integer
If "Invalid other" is returned in the Acyclic Message
Status Word in the header of the response, information
about the fault can be found here. Refer to Acyclic
Message Status Word (page 218)
0001h: Address out of range.
000Ah: Failed to execute request. Refer to Return Codes
(page 219) for additional information.
000Bh: Remote station failure. Refer to Return Codes
(page 219) for additional information.
00FFh: gateway not initialized.
