Variable Name
Size/Type Description
Out - MailBoxData
Multi-variable
nested DDT
For details, see Modbus DDT (page 98).
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 - 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
In - StationsStatus[ ] 127 element
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).
In - Message Done
1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP response
is successfully received.
In - Message Error
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.
