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 - Operate
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 begin and
continue normal network cyclic polling and acyclic messaging.
Set this bit to one (1) whenever no other messages are active
and you want to send this acyclic message.
Out - Stop
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 stop
normal network cyclic polling. Some acyclic messaging can
still be accomplished in this mode. Set this bit to one (1)
whenever no other messages are active and you want to send
this acyclic message.
Out - Clear
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 clear slave
diagnostic faults and re-initialize the PROFIBUS network. Set
this bit to one (1) whenever no other messages are active, the
network mode is currently set to STOP, and you want to send
this acyclic message.

16-bit
Integer
Default value for Quantum processors with built-in Ethernet
port is 254 (16#FE00 hex)

Block for TCP/IP Ethernet" in Quantum Help Files, or

and DDTs (page 137)
In - OperationActive 1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP message
has been initiated and is being processed.
In - OperationError
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 -
OperationSuccess
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.
