Critical Control & Safety (SIL-3) Applications

System Architecture

Unlike other systems, the RTP3000 TAS  was designed to meet the stringent requirements of IEC61508 2010 without later additions or modifications.  The product requirements contained two other major items, the functionality of a DCS and the speed of a PLC.   To meet the DCS requirements all Analog cards are designed with 16 ADCs and DACs.  A multi CPU architecture that adds processing capability as the system is expanded makes it the fastest control system available and satisfies the PLC requirement.  The software package, NetSuite, provides all the software components you will need.  By making a simple OS change, you can utilize the same set of hardware and the same software suite for your SIS, DCS, or PLC applications.  This is RTP's definition of Seamless Integration. 

Costs Less

  • Single, Dual, or Triple Redundant
  • Low Cost Hardware
  • Software Site License – Unlimited Use
  • No Maintenance or Upgrade Cossts
  • 10-year Warranty on Hardware

RTP entered the SIS market with a stated goal being to bring down the cost of Safety Systems.

SIS systems are a necessary part of many industrial processes, but they should be affordable.  RTP strives to make that happen.

All RTP hardware and software is produced by RTP at its corporate facility in Pompano Beach, FL.  By keeping this activity in house, implementing best in class manufacturing techniques and make low-cost manufacturing a corporate competency, RTP is able to provide an advanced product at a reduced price reducing the capital cost involved in the initial purchase of a system.

Our unique software licensing policy which sells each user an unlimited site license on our comprehensive NetSuite software package further reduces capital costs.  There are absolutely no limits on the use of the NetSuite package as long as it is used on the site to which it is licensed.

365 day a year, 24 hour a day phone support is included in the cost of the product.  There are no support contracts to purchase.  Software upgrades are included in the site license fee.  There is no software subscription service.  As new releases are completed, they are made available at no extra cost to all licensed users.

We believe our products are so good that you’ll want to buy more and we believe that you should only pay us money when you want to buy things.  There should be no ongoing ownership fees.

So, RTP saves you money on the initial purchase price of the hardware and software that you buy, and RTP saves you money on the ongoing cost of ownership.

Or, as we say, RTP products COST LESS.


Runs Faster

  • Constant 5 Millisecond Scan
  • 12-16 Millisecond Response Time
  • Extensive Diagnostics
  • More Processing Power

Our 49 years of experience in the controls industry allows us to build a better product.  RTP applies technology to critical control and safety applications better than any other company in the world.

The process industry has been conditioned to believe that speed is not important, but that’s just not true.

In control applications, no one would argue that the closer the Process Variable is kept to the set point, the better.  That will mean higher quality or less waste or less off-spec product.  All of those things are good and all of those things are a function of speed.  All too often, we use expensive offline process optimization packages simply because the controls systems being used aren’t capable of controlling the process in real time.  This is not a problem with the RTP 3000.  Run your process under tighter control and increase profitability.

In safety applications, a fault should be cleared as quickly as possible.  With many so called state-of-the-art SIS systems, this can be 200 to 500 Milliseconds.  The RTP 3000 TAS has a response time of 12-16 Milliseconds, more than 90% faster.  A faster shutdown can mean less damage or no damage to equipment, personnel, and the environment.  If the process can really stand a longer response time, the 3000 can verify the fault condition over multiple scans preventing an unnecessary shutdown due to spurious information.  So speed in control applications means less damage or fewer spurious trips.  In other words, less cost for the end user.

How can the RTP 3000 TAS be so much faster than other systems?  Simply put, RTP applies technology better.  First, the RTP 3000 TAS has more processing power.  With the combination of powerful Intel microprocessors, independent communications channels, and RISC based processors, RTP brings more processing power to the task.  Then, as the application grows, additional processing power is added.  So the processing capability grows with the application enabling both higher performance and advanced diagnostics.

Speed does matter.  That’s why the RTP 3000 TAS RUNS FASTER.



Never Stops

  • Highest MTTFS – Fewer Nuisance Trips
  • Extensive Diagnostics – No Need to Stop to Determine the Problem
  • Every Component is Hot Swappable – No Need to Stop to Repair the System
  • Unlimited Online Modifications – No Need to Stop to Implement Changes

A Safety Instrumented System (SIS) should always take the process it protects to a safe state when it is required to do so . . . and it should never interfere with the operation of the process at any other time.

When discussing uptime on processes with Safety Instrumented Functions (SIF’s) implemented, the discussion always turns to MTTFS or Mean Time to Fail Spurious or Safe.  This is a measure of how often your SIS will take your process to a safe state for no reason.  That’s another way of saying how often your SIS will shut your process down.  RTP’s MTTFS is over 10 times that of all other SIS systems.  That means 90% fewer nuisance trips.  So, we could drop this issue right here . . . except.

Most SIS systems are fault tolerant, but what does that mean.  In order for fault tolerance to save money, the SIS system must be able to diagnose a fault, continue to operate in the presence of the fault, and allow online repair of the fault within the designed repair time.

Through increased processing power that actually increases as the application grows, the RTP 3000 has extensive diagnostic capability allowing it to diagnose almost any fault.  When configured as a redundant or triplicated system, the 3000 will continue to operate in the presence of a fault and any fault can be corrected online in a matter of minutes, meaning no downtime is required.

With IEC61511’s requirement for continuous improvement, SIS systems routinely require changes.  Once the need for a change has been identified, the change cannot be delayed until the next turn around.  It must be implemented immediately.  The RTP 3000 allows for unlimited online changes.  Changes can include logic modifications, the addition or deletion of I/O and addition or deletion of I/O chassis..

Couple all the above with RTP’s industry-leading reputation for reliability and you have a system that . . . NEVER STOPS!


RTP Corporation: 49 Years of Technological Excellence

Founded in 1968, RTP began operations as a division of Computer Products, Inc., and in July of 1997, RTP Corp. became a privately held company. For its first twenty-seven years in business, RTP provided high-performance data acquisition systems to the worldwide nuclear market and I/O front-end subsystems for minicomputer driven data acquisition and control systems at some of the world's largest industrial companies. These process control applications were typically characterized as being located in harsh environments, yet with demanding requirements to provide accurate analog measurements under extreme environmental and EMF/RFI conditions.

With a solid foundation of field-proven, high-performance, and high-reliable I/O hardware, RTP decided, in 1995, to expand its product offering, and added control software and a control processor to its I/O front-end subsystems and introduced its Hybrid Control System.  In 2002, the company entered the safety market with its SIS product offering. The decision was not to develop just another safety system but to have a “Best in class” system with the following objectives.

RTP would develop an architecture that would have:

  • the highest speed,
  • the highest availability, and
  • the highest integrity of any Safety System.

The system would be designed from the beginning to be IEC61508 compliant.  This would be a design criteria, not an afterthought.

In 2003, the company introduced the 2300, the Single, Dual and TMR DCS versions of the system. Six hundred systems were shipped as DCS systems before RTP received SIL-1 to SIL-3 certification from TÜV in October of 2006. 

This version of the technology was the RTP 2500.  It was certified for SIL-2 applications in simplex architecture and for SIL-3 in redundant and TMR architectures.  In May 2008, a second TÜV certificate was issued for revisions to the RTP 2500.

Two years after receiving TÜV certification for the 2500 system, RTP announced the next generation system.  The 3000 SIS, built on the technology of the 2300 and 2500, offers increased speed, availability, I/O density, and ease of use.

RTP introduced the RTP 3000Q in 2010, the first true Quad SIS architecture, providing true 3oo4D technology and MTTFS numbers in excess of 100,000 years, essentially eliminating nuisance trips. At the same time, the RTP 3100, Hybrid Control System was introduced.  Using the same hardware and software suite, the 3100 allows control options not consistent with SIS systems and industry’s most tightly integrated control and safety platforms.

RTP recently introduced the RTP 3000 TAS, its second generation Quad SIS architecture, providing enhanced 3oo4D technology and MTBF numbers in excess of 60,000 years, essentially eliminating nuisance trips. This product demonstrates RTP’s continued commitment to maintain its position as the technology leader.  By working with and listening to its customers and understanding core technologies, RTP will continue its technological leadership, investing in the application of technology to solve Data Acquisition needs in the Nuclear Power, and Control and Safety needs in the Process Control and Safety markets.
