3.3 Establishing a Connection to the Scanner
The first step in programming the System 7000 scanner is connecting to one or more of its TCP and UDP
ports.
TCP Command Port
 You must connect to the command port in order to send commands to and receive responses
from the scanner.
 You do not need to connect to this port if you are planning on using StrainSmart to control
the scanner and you only wish to perform monitoring of the UDP data.
TCP Data Port
 Connection to this port is required if you wish to download file data or directory listings from
the scanner.
 If you are not recording data on the scanner (i.e. you are only monitoring real-time data) or if
you do not wish to download files you do not have to connect to this port.
UDP Real-time (Online) Data Port
 You must set your program up as a listener on the multicast broadcast from the System 7000
if you wish to monitor real-time data.
 If you are not monitoring real-time data, you can ignore this data port.
UDP Event Port
 You must set your program up as a listener on the multicast broadcast from the System 7000
if you wish to receive event, status, and error messages from the Scanner.
 If you don’t wish to receive these messages, ignore this port. It is not required to receive
status and error messages via broadcast as you may query the system for status information
via a TCP command.
Information on configuring the system network connections is contained in the “System 7000 Instruction
Manual”. You may connect to more than System 7000 scanner in a single application.
Programming tips:
1) If you cannot establish TCP connection with a scanner, verify that you can successfully “Ping”
the IP address. If you cannot communicate with the scanner with the “Ping” command, your
program will be unable to communicate as well.
2) If you still cannot establish communication, verify that no other application is currently
connected to the scanner (such as StrainSmart or the System Calibration utility).
LabVIEW Connection to the scanner is done when you pass the VISA
resource name of the command and data ports to the
Initialize VI.
Active X Connection to the scanner is done by setting the, IPAddress
CommandPort and DataPort properties then calling the
Open() method.
