Scalability
ControlWave Express can also be combined seamlessly with other members in the ControlWave family of products. For remote applications requiring more I/O flexibility, ControlWave Micro provides a modular RTU/PLC expandable up to 14 I/O modules.
For natural gas well site and measurement station automation, ControlWave single and multi-run flow computers share a common architecture with the ControlWave family of products and all meet API
21.1 requirements for multiple meter runs.
For in-plant control applications, ControlWave and
ControlWave Micro are powerful, flexible PLCs.
ControlWave offers the greatest local and remote I/O expansion to hundreds of I/O points, up to three Ethernet ports for network segmentation, plus CPU, communication and I/O redundancy capability.
IEC 61131-3 process languages for batch, continuous and discrete control: Function Block Diagram, Structured Text, Sequential Function Chart, Ladder
Logic Diagram and Instruction List.
ControlWave Designer includes an extensive library of more than 200 basic IEC 61131-3 functions and function blocks common to many IEC 61131-3 based products. These include:
•Flip-flops, Counters & Timers
•Ladder diagram functions – coils and contacts, etc.
•Numerical, Arithmetic & Boolean functions
– Sine, Cosine, Add, Sub, Square Root, And,
Or, etc.
•Selection & Comparison – Min, Max, Greater than, Equal, Less than, etc.
• Type conversions – Integer to Real, Boolean to
The combined benefits of the ControlWave family Word, etc. of products integrates your wide area network with
your local area network.
Open Standards For Programming, Network Configuration and Communication
Only ControlWave brings the perfect combination of industry standards to minimize learning, engineering and implementation costs.
By adhering to such industry standards as Ethernet, TCP/IP, Microsoft Windows®, COM/DCOM, FTP, OLE and ActiveX, ControlWave is able to achieve the highest degree of openness in control system architecture and bring the optimal process efficiency and productivity needed to ensure a successful system implementation.
ControlWave Designer with ACCOL III
To minimize your engineering and development time, we have adopted the international standard for PLC programming, IEC 61131-3. ControlWave
Designer is a fully IEC 61131-3 compliant programming environment for the ControlWave family of products. ControlWave Designer includes all five
ACCOL III
In addition to the basic functions and function blocks, ControlWave Designer brings the benefit of over twenty years of SCADA and plant control experience in Emerson’s Bristol ACCOL III function block library. ACCOL III includes over sixty function blocks valuable for use in oil & gas, water & waste and process measurement & control applications. Further,
ACCOL III is designed to take full advantage of the significant features offered by ControlWave.
Briefly, this library includes function blocks for:
•Average, Compare, Totalize
•Scheduling & Sequencing
•PID & Lead/Lag
•AGA gas flow and liquids calculations
•File handling
In addition, ControlWave ensures data integrity, in the event of a communication interruption, by storing critical time-stamped alarm and historical data in the controller memory. This data is then securely retrieved when communication is restored.
