Scalability
ControlWave ExpressPAC can also be combined
seamlessly with other members in the ControlWave
family of products. For remote applications requiring
more I/O exibility, ControlWave Micro provides a
modular RTU/PLC expandable up to 14 I/O mod-
ules.
For natural gas well site and measurement station
automation, ControlWave single and multi-run ow
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, exible 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.
The combined benets of the ControlWave family
of products integrates your wide area network with
your local area network.
Open Standards For Programming, Net-work Conguration 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 efciency
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 program-
ming environment for the ControlWave family of
products. ControlWave Designer includes all ve
IEC 61131-3 process languages for batch, continu-
ous 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-ops, 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 •
Word, etc.
ACCOL III
In addition to the basic functions and function
blocks, ControlWave Designer brings the bene���t of
over twenty years of SCADA and plant control expe-
rience 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 pro-
cess measurement & control applications. Further,
