In this day of liability and
regulatory requirements data integrity is becoming
of ever increasing importance. Missing data
in compliancy reports is typically a cause for
great concern. Documenting the reason for data
loss and the routine inspections to verify the
integrity of the operation during blackout periods
is very costly.
Unreliable links in the communication chain
come in many forms from broken cables or antennas
to failed host computers to all-out "acts
of God". In traditional data collection
schemes data is generated in the first link
of the chain but not collected until the last
link. This architecture guarantees that broken
links mean missing data.
INS solutions for data collection are modular
and scalable - aimed at eliminating the concern
of a less than reliable communication network.
Comprised of hardware-based data loggers, server
software, and a process historian, the iDatalog
system is designed to peacefully co-exist with
your existing control system while providing
the ultimate in security for your valuable process
data.
Data can be acquired from existing control
systems by various means including isolated
discrete or analog I/O or by direct communication
to control devices such as programmable logic
controllers.
INS solutions for Secure
Data Collection provide: |
- Scalable solution that can collect
from one data logging station to thousands
of stations
- Collectors that support open standards
such as OPC, Modbus, Ethernet, TCP/IP
for real-time communication. Transmission
media such as LAN, serial, telephone
modem, and radio are also supported.
- Communication Redundancy
- A secure collection mechanism that
records and transfers using a proprietary
binary protocol. When transferring records
over the internet, we use a registered
port number making records virtually
invisible to the casual observer.
- Flexible collection methods in which
records can be captured on either periodic
or event basis
