General Description
NetScan is an advanced hybrid data recorder that combines the desirable features of paper-based stripchart recorders
with the latest PC-based data acquisition technology, including Ethernet/Internet-based data logging and control.
The device provides from 16 to 128 isolated channels. In addition, 32 digital outputs can be set to automatically
function as alarm outputs, or be controlled individually through a network. Eight inputs provide a means of reading
digital input status through the network. An outstanding feature of NetScan is that the device can communicate
remotely through the internet. This feature is made possible by the system’s use of TCP/IP protocol.
In addition to chart displays, NetScan can be used to display “meters” in digital, analog, and bar graph formats. The
unit can measure up to 64 differential input channels and can easily be expanded up to 128 channels with the use of
an expansion module.
NetScan is well suited for temperature and voltage measurements requiring channel-to-channel isolation. This
isolation is made possible by the use of individual relays on each of the 64 channels. The unit provides 500 V
isolation for voltage inputs and 200 V isolation for thermocouples. The instrument scans at a rate of up to 147
channels per second and includes a single-channel burst mode for digitizing waveforms at rates up to 20 kHz.
Measurements include:
•
isolated temperature from thermocouples
•
DC volts
•
AC volts
•
waveforms
NetScan includes ChartViewNET, a software program which provides a Windows-based graphical-user-interface
approach to obtaining data collection and display; PostView, a post-acquisition data review program; and ScanCal, a
software application that automates instrument calibration.
Optional software, shipped with separate documentation, includes the following:
CIMScan

is a HMI/SCADA application. A single screen can display data from [and control outputs of] several
NetScan devices connected through a network. With CIMScan, users can customized applications accessing
thousands of channels from network-connected NetScan devices. CIMScan does not require programming
knowledge.
ScanServer

is a driver that permits access to multiple NetScans from popular HMI/SCADA applications
(including those from Wonderware

and Intellution

.) ScanServer supports OPC/DDE-compliant environments,
such as Microsoft Excel

