PART 3 -
DAS SPECIFICATIONS
A. FEDERAL REGULATORY REQUIREMENTS
1. The DAS shall comply with US EPA 40CFR60, 40 CFR75, State of [Insert
State]Regulations, and any other
requirements of the attached permit.
B. DATA ACQUISITION SYSTEM
1.The DAS shall provide for automatic
data acquisition, data processing, report generation, graphical display of data,
printing and/or storing reports in electronic format, email transmission of
reports and alarms, archival storage of data, and providing remote access to the
system via network connection or modem.
2. The system shall be utilize Windows
2000â
as the operating system. No hybrid Unix/Windows systems will be considered. The
Data Acquisition System (DAS) shall be designed from the ground up as a Windows
application taking full advantage of the inherent connectivity allowed by ODBC
compliant applications. The DAS must be designed around a well proven,
commercially available, Database. The report generator shall also be a
commercially available, user accessible product.
3. Software and operating system
requirements: The system shall:
a. Have a user-friendly
Windowsâ
interface.
b. Offer password protection
on multiple levels.
c. Allow the authorized operators to
edit data, reason codes, and corrective actions using a user friendly editing
program that allows for filtering and block editing of the data.
d. Allow the
authorized operator to log out of service, out of control and off-line status.
e. Allow the
authorized operators to archive data automatically or on demand.
f. Allow
authorized operators to create assorted graphical displays of real time or
historical data.
g. Allow
authorized operators to create tabular displays of real time data.
h. Prepare reports automatically or on
demand.
i. Allow for user design and/or
modification of reports.
j. Allow remote access to all system
functions via network or modem.
k. Allow expansion to accommodate revised
regulations and/or measurement/calculation requirements.
l. Be designed with server-client
architecture.
m. Be capable of interfacing and communicating with workstations via the plant
LAN/WAN.
n. Be capable of transmitting alarm
messages, reports, etc. via a Microsoft Exchangeâ
email server.
o. Incorporate a wizard interface that
walks the user through the configuration of displays and EDRs.
p. Allow for easy sharing of data with
common Microsoft software products such as Wordâ,
Excelâ,
and Accessâ.
4. System hardware: The contractor
shall provide a complete system designed for the best operation of the supplied
DAS. The configuration of the hardware will be the supplier’s responsibility but
the hardware must have state of the art speed and capacity ratings. The
computer should have the at least the following specifications:
