Variable Name Size/Type Description
Out - GetLiveList 1
Single-Bit
Boolean
This is the bit your control and sequencing logic will use to
trigger a message to tell the PROFIBUS Master provide a
list of active slave nodes. Set this bit to one (1) whenever
no other messages are active and you want to send this
acyclic message.
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 - RoutingRegister 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 - ListOperationActive 1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP
message has been initiated and is being processed.
In - ListOperationError 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 -
ListOperationSuccess 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.
In - StationsStatus[ ] 127 element
8-bit Byte
Array
Each byte will contain one of the following codes indicating
type of node present at that node address:
00h: Slave Station
01h: Master Station not yet ready for Token ring (station
physically attached to the bus but not configured or polling)
02h: Master Station ready to enter Token ring (station is
configured but not polling; there is not yet any Token
transmission)
03h: Master Station in Token Ring (Token transmission
through the station; station is fully operational)
04h: Station does not exist
In - Fault 1
16-bit
Integer
For details on Fault Codes, see Acyclic Message Status
Word (page 218).
In - Return Code 1
16-bit
Integer
For details, see Return Codes (page 219).
