Knowledge Base and How-To's

The following is a list of introductory information on SCADA and Telemetry technologies:

Introduction to SCADA
A SCADA system is a common process automation system which is used to gather data from sensors and instruments located at remote sites and to transmit and display this data at a central site for either control or monitoring purposes.

Wireless SCADA
Wireless SCADA is required in those applications when wireline communications to the remote site is prohibitively expensive or it is too time consuming to construct wireline communications.

Wireless Communications Primer
Wireless Communications: Range is dependent on radio transmit power, cables losses, antenna gain, and radio path losses, and receiver sensitivity. A line of site path is desirable but not totally necessary for radio data communications.

Cellular SCADA
Cellular technologies for SCADA may be considered when wide area coverage is required and the cost of alternative technologies (Private Radio systems, Satellite, etc...) is uneconomical.

Cellular SCADA Networks
IP Packet data technology of cellular networks can enable flexible IP-based SCADA and data communication.

Cellular Well Monitoring
A SCADA Host can use cellular modems to poll individual gas wells or as a bridge to a customer's existing network of private radios.

Cellular Hosted SCADA
Hosted SCADA Solutions using Client-Server SCADA Host software enables clients to login to a secure website to monitor their remote sites.

Cellular End-to-End I/O
End-to-End I/O Telemetry is used when a small amount of I/O needs to be replicated at another site.

IDEN SCADA
IDEN is a wireless cellular networking technology available from a number of Cellular Providers. IDEN SCADA takes advantage of these features by exploiting the IP services such as SMS email, Packet Data or Wireless web. If Packet Data is used, this enables IP hosts to access their remote equipment via TCP/IP.

Satellite Pipeline Monitoring
Remote monitoring and control using Satellite technology.

Satellite Remote Access
High Speed Satellite Internet gives Remote Access for SCADA Maintenance & Configuration.

Satellite Flow Monitoring
Cost-effective Remote Flow Monitoring using Satellite technologies.

Wireless Instrumentation
Wireless instrumentation are used in the industries to monitor and control operations.

I/O Telemetry
I/O Telemetry systems transmit analog or digital signals and replicate them exactly at another site.

Wireless I/O
Wireless I/O can be used to transmit and receive I/O signals at long distances.

Alarm Autodialer
Alarm dialers (also referred to as ARU, Voice Dialers, Alarm Callout Systems) are systems that dial out on alarm conditions to alert personnel via telephone, pager, fax, or email.

Modbus Protocol
Modbus protocol originally developed by Gould Modicon for their PLC family has become a defacto standard in industrial control communications.

Internet & Web-based SCADA
Internet SCADA or Web-based SCADA makes use of IP technology in SCADA and can range from IP tunnels over satellite, frame relay, fiber, radio to link SCADA networks to central office to individually IP addressed instruments or devices or web-based SCADA Host MMI Software such as NETSCADA.

License Free Wireless I/O
With no licensing delay, no annual licensing fees and channel availability, unlicensed radio communication opens up the opportunity for more widespread use of SCADA and Telemetry applications in the oil and gas industry.

Multi-Access for FloBoss / ROC
Bentek Systems' RS232 Splitter allows the operator to simultaneously access the FloBoss / ROC with a Master through one serial port.
