Variable Name
Size/Type Description
Out - StopSlaves
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
Stop acyclic message to all slaves which have their Out-
SlaveNumber array element set to 1. Set this bit to one (1)
whenever no other messages are active and you want to
send this acyclic message.
Out - StartSlaves
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
Start acyclic message to all slaves which have their Out-
SlaveNumber array element set to 1. 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 - SlaveNumber
126-element
8-bit Byte
Array
Enter 0 or 1 for each array element before you trigger the
Start or Stop acyclic message
0 = Do not change this node (ignore acyclic message for
this node)
1 = Change the state of this node to Stop for Stop acyclic
message or Start for Start acyclic message (acyclic
message affects this node)
Out - Routing Register 1
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

In -
StStOperationActive
1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP message
has been initiated and is being processed.
In - StStOperationError 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 -
StStOperationSuccess
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.
