What is DCS?
DCS (distributed control system) which comes from the DCS Distributed Control System includes the main control section, which is similar to the PLC, but bigger talent than Either control, Batch, Sequencial, Analog Control and Advance Contol and user interface which is similar to Scada, including the history, History, and other stores.
Because the control system in the first session will be used as a control Relay system. But soon evolved into PLC by language programming of PLC, it has all five languages: Ladder (LD), Instruction List (IL), Sequence...

Conventional Motor Control Centres (MCCs)
Conventional low-voltage Motor Control Centres (MCCs) are ubiquitous in the oil and gas sector and in general, meet industry requirements for safe, reliable and efficient operation. So, are there any real benefits to be gained by choosing the new generation of Intelligent Motor Control Systems (IMCSs) for future projects? The answer is undoubtedly yes except, perhaps, for the most undemanding of projects.
In a conventional MCC, the power switching and protection components that make up the individual starters are linked to the device that provides...
Integrated Safety And Regulatory Control
Addressing functional safety and regulatory control in a single system has been a challenge for many years – even more so when systems are destined for use in a hazardous area.
A technical solution from Siemens is said to offer these combined capabilities delivering benefits such as a simplified safety verification process, tangible cost savings and scalability Ian Curtis, safety consultant for Siemens Industry Automation, explains.
The functional safety and hazardous area protection world’s are often closely associated. However, when it comes...
Wireless Level Switch
Emerson process Management reports that intelligence inside its switches are now also able to distinguish between material build-up on the fork and a high product level, reducing the need for inspection in the field. Electronic Device Description Language (EDDL) is used to enable the level switches to be configured and monitored from the same device management software as a plant’s other intelligent devices such as pressure and temperature transmitters.
Adding hardwired level switches into an existing plant can be costly due to the cost of laying...
SCADA Virtualisation
Virtualisation for SCADA systems brings many benefits such as time and cost savings, greater levels of security and operational efficiency advantages. Tony Chapman from Siemens Industry Automation highlights some of the key areas where SCADA virtualisation can add real value.
As automation solutions become increasingly complex, it follows that the effort required to maintain both hardware and software will also increase. PCs must be provided with suitable specification and operating systems to support the applications. Whilein operation, these...
An alternative to DCS or PLC/SCADA?
Traditionally, users have had a choice between a DCS or a PLC/SCADA approach when selecting a control system for use in process control applications. Richard Sturt, Rockwell Automation business development manager, process Industries, believes that Rockwell can offer a solution for users needing elements of both of these approaches.
A key benefit of traditional DCSs was that the suppliers took a ‘systems approach’ and it was designed for large scale applications. Much of the work of integrating different parts of the system was taken care of by...
Expansion Advantages of Wireless Controls
Josh Thompson, principal, Point Source, says that wireless networks provide facility managers with a number of options to both save money and expand into areas they might not otherwise have been able to reach. After all, running a wire requires additional materials and a hole in the wall.
"The current cost of materials, conduit and cabling can push the BMS outside of the return-on-investment window. Wireless fixes that in many cases," Thompson says. "In an industrial facility, there are applications where sensors and controls would be desirable,...
The Greatest Impact On Automation And Controls In The Next Five Years
Software abstraction – Graphical system design is a great example how software abstraction increases the productivity of engineers and scientist from different industries and application areas. Embedded processing – The ever increasing processing performance and the lower footprint of processors enables companies like National Instruments to bring technologies like multi-core processors into the industrial space and create off-the-shelf embedded systems that engineers and scientist can adopt for the most demanding applications. Reconfigurable...
Automation Market of National Instruments Products
National Instruments provides products and platforms that enable engineers and scientists to design any system that needs measurement and control, using the graphical system design approach. In this effort, we design products that can be applied across many different industries and application areas. In fact, no particular industry accounts for more than 15% of NI revenue. Industrial automation is of course an important element of the NI business and we have a lot of customers who are using our industrial grade embedded platforms to...
Energy harvesting: a practical reality for wireless sensing
There are some very exciting high growth projections for wireless sensing for the Automation industry. More sensors mean more process efficiency, lower operating costs, lower maintenance costs, higher reliability, and greater safety. Wireless sensing provides the opportunity to install masses of sensors with virtually no cost of installation by reducing the need for cables carrying the signals from the field to the control room. Wiring costs can easily be 80%, or more in a hazardous area,...

Technology in the PLC
PLC has been developing the capabilities of simple form and transform the same price level ever. And the development of which will go on. What’s left to do and tons more or no less interesting question.
As a related technology. We conclude the development of PLC from the past to current and upcoming follows.
1) patterns of language use. Still can not say that it will not use the ladder diagram (Ladder Diagram), but the role of the function block (Function Block) is more or even a programming language (Instruction List), which will combine both...

Solve CP1H R88D Servo Motor Controller
I work around a CP1H R88D servo with a pulse output 0 problem. All power settings are standard, except for the electronic gear ratio. The example is the Handbook of 2000 pulses per revolution motor set.
Fine adjustment of the drive car (one horizontal spindle).
I have the move to Omron (power) function block in the CP1H.
The distance between the CP1H and the servo is about 6 m (2 m). The drive is a Panasonic with brake and encoder (not absolute).
Two cases:

Monitoring memory space in the PLC.
Often used in the PLC to consider that choosing which version to use the CPU will have enough space to run the program. The count is difficult enough to evaluate. Because the function of machines, each machine has a different way of thinking is difficult and complex simplicity. And do not depend on the number of I / O.
So if you find ways to estimate a cursory I can do it without writing a program in advance because the CX-Programmer. Can be simulated. (Must...

History of PLCs
Today i have article that story in PLCs,Twenty-five years I was in my last year with Allen-Bradley PLC and a specialist and educator. I grew up with the PLC in 1774, the PMC. What a trip through the PLC-2, PLC 3, PLC 5, computer-based programming instead of a luggable terminal and a 10 MB hard disk for the PLC-3 GA module for remote data collection and programming remotely through the RM modules.
A laptop for programming (Data General) was more than $ 8,000. Hard drive space is outrageous expensive, and Windows will not be used. PCs were ahead,...

Automation Standard for PLC programming
The IEC 61131-3 standard for PLC programming is a non-standard, since many of the rules are so general, and because there are so many exceptions and extensions of the original proprietary software definitions and original promise of portability of software between devices are open.
Capitalism is a great positive force that could improve trade and increase economic benefit and mutual well-being of all: that is, until a few million bad apples begin to cut. Unfortunately too short-sighted and selfish business interests and their puppets legislative...
