1.0 System Set Up
The data acquisition system is based on the Lookout HMI/SCADA (Human
Machine Interface / Supervisory Control And Data Acquisition) system
manufactured by National Instruments, Austin, Texas. Lookout is a PC based
software that operates on Windows 9x / NT/2000/Me/XP operating systems.
1.1 Minimum Hardware Requirements for Lookout
The following are the minimum computer requirements
Pentium Class PC running at 90 MHz.
•
32 MB RAM (recommend 64 MB)
• 200 MB free hard disk space.
• Windows 98/95, Windows 2000, Widows XP or Windows NT version 4.0
with the latest service pack.
• Network card and TCP/IP networking installed on PCs to be connected
(this is required only if the Online SCADA system is to operate on a
multi-node network of PCs).
Note: The above are the minimum requirements of Lookout. It is always better to
have as fast a computer and as large a hard drive and RAM capacity as possible.
Because the Online SCADA application is to run 24 hours a day, the computers
should have some form of AC power surge protection. A suitably sized
uninterruptible power supply (UPS) provides the ultimate protection.
1.2 Testing TCP/IP
The Lookout application for the turbidity data acquisition has been developed
such that it can be installed and operated on a multi-node network. It can,
however, be installed and operated from a single PC node. The TCP/IP set up is
required only for networked operation.
The network must be properly set up with the TCP/IP protocols installed. It must
be possible to ping any computer on the network. Please note that Lookout
currently does not support Novell networking.
Please disregard this section if the data acquisition operation is to be done only
from a single computer.
