The NIDataSockets communication driver implements communication with the National Instruments software. This includes LabView and any others that are compatible with the National Instruments Data Sockets interface.
Communication Driver Name: NIDataSockes
Implementation DLL: T.ProtocolDriver. NIDataSockets.dll
Protocol: National Instruments Data Sockets
Interface: TCP/IP
PLC types supported: National Instruments Labview
Multi-threading: User defined
Max number of nodes: User defined
PC Hardware requirements: Standard PC Ethernet interface board
Supported Operands: Any tag defined on the target system
Maximum size of blocks: Defines the maximum number of addresses in a read block
Message Format: Defines the protocol used for the Data Sockets communication
Options: DSTP, OPC, LOOKOUT, HTTP, and FTP
TCP/IP:
NodeConnections: Defines the maximum number of parallel requests that will be sent to each node (asynchronous communication)
TCP/IP:
Ex: 192.168.1.1
Ex.: 122:168.1.1/MyTags
The syntax for the communication point is: InitialBranch/TagList/Tag1
If you have a lot of tags sharing the initial branch, you can remove the InitialBranch from the Point address and move it to the Node-Station address. |
The status of the driver's execution can be observed through the diagnostic tools, which are:
• Trace window
• Property Watch
• Module Information
The above tools indicate if the operations have succeeded or have failed. A status of 0 (zero) means communication is successful. Negative values indicate internal driver errors, and positive values indicate protocol error codes.
