Variable Name
Size/Type Description
Out - IPAddress[ ]
4-element
16-bit
Integer Array
Each of the four integer elements holds one octet of the
message destination device's IP Address. For this
application, it will be the the ProLinx gateway's Ethernet port
address.
Out -
GetDatabaseInfo
1
Single-Bit
Boolean
This is the bit your control and sequencing logic will use to
trigger a message to retrieve information about the
PROFIBUS database. Set this bit to one (1) whenever no
other messages are active and you want to send this acyclic
message.
Out - Routing
Register
1
16-bit
Integer
Default value for Quantum processors with built-in Ethernet
port is 254 (16#FE00 hex)
For details, see "MBP_MSTR, Ethernet (Quantum) - Control
Block for TCP/IP Ethernet" in Quantum Help Files, or
Quantum Communication Control and Data Buffer Variables
and DDTs (page 137)
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 in this variable.
0001h - No database in FLASH memory, or download is in
progress.
In - Input Length
1
16-bit
Integer
Total Input Length
Sum of all Input lengths for all slaves in the database, in bytes
In - Output Length
1
16-bit
Integer
Total Output Length
Sum of all Output lengths for all slaves in the database, in
bytes
In - PROFIBUSInput
Size
1
16-bit
Integer
Required Initialization Input size for the current database. If
the slaves are located in a contiguous block, this size is the
same as the Total Input Length.
In -
PROFIBUSOutput
Size
1
16-bit
Integer
Required Initialization Output size for the current database. If
the slaves are located in a contiguous block, this size is the
same as the Total Output Length.
In –
PROFIBUSCRCInfo
4-element
16-bit
Integer Array
This array holds two 32-bit values which are the PROFIBUS
and Module CRC32 checksums. These values also appear in
the gateway status variables and in ProSoft Configuration
Builder (PCB).
In - DatabaseActive
1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP message
has been initiated and is being processed.
In - DatabaseError
1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP response is
not successfully received. When this bit is set, it indicates your
control and sequencing logic should retry the command.
In -
DatabaseSuccess
1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP response is
successfully received and the PROFIBUS cyclic input data
variables have been updated.
