Several automation solutions (DCS, PLC or PC-based hybrids with packages Wonderware) may serve a particular set of automation requirements.

The overall architecture of the processing performance, comfort and easy operation meet the future needs such as integration with the ERP can not be guaranteed by all the possibilities of this type. A real DCS is expected to meet all requirements for the genre.

DCS = Distributed Control System This is the pure definition of a DCS. Their request for bids is a reader’s definition of what they want / need for their installation.

Too often engineers get hung on the generic classification (PLC, DCS, PAC, etc.) Today, many of the control products on the market in fact be implemented in a DCS configuration.

I’m not a big fan of the Siemens product line, but the possibility for controllers to communicate with each other and with HMI makes it possible to distribute control between the controllers of many working together to run your plant. Hence more PAC / PLC can be configured in a distributed control architecture.

The other lines refer, by definition, “other” properties of the control system. Some systems work best to distribute the control and I / O, while others work best in a single activity. Each system has strengths and weaknesses, so you must use the system to better achieve what you need in one system.

Be associated with Siemens, veritably you chose to highlight aspects of the scheme with Siemens, in comparison with modern offereings or more other system vendors in question.

For reasons best known to Siemens India and their system integrators (which only Siemens offered in India!) Solo PCS7 platform also offers the Power Plant.

Like your way of comparative tabulation product functionality with Siemens T3000 PPA for Power Plant Automation (compared with ABB 800xA, ExperionPKS Honeywell, Foxboro IA and Yokogawa CS3000 platform solutions.

Siemens in the family (I am also a member), we have different DCS systems. One is the PC-based automation system for TPP / combined / gas turbines / plants Teleperm XP-Home (T3000)

The second, ‘PCS7 system’ as well as chemicals, oil refining and gas, Pharma, IND. gas, glass, cement, also used for projects, Hydro Electric Power. This system is capable of SOE, monitoring and control of the car and other key functions.

So both systems have a place in the Power Plant Applications.

Back in the 90s. Yes, there was clear demarcation between a DCS and PLC system, simply because both were built to serve different funtions and applications. But today it is no more clear line that you can use the power of telecommunications to distribute the PLC and I / O is too large disctance make them more distributed controllers use & powerful all operations are possible in all developing countries today.

Telling PCS7 is not a true DCS would be wrong because it really has evolved into a hybrid DCS can handle almost all activities with the library rules. Based on the strengths of this library will make it more suitable for some areas than others and vice versa.

For example: The Library Power Plant is not as large as that using PCS7 well T3000 on a project of enormous power is not what I recommend Siemens. I remember the group that is responsible for Siemens Power Generation has always done its CS during the last 25 years and therefore knows what is required and without family Teleperm in what is today. Great for power plants not others.

Similarly, the group is responsible for PCS7 works with all other industry segments are expected to power and then evolved into the family SIMATIC PCS 7 combines strength and development funtionalality a DCS instruments & Engineering HMI interface. And ‘quite different from the instruments SIMATIC PLC and HMI.

I would also like to mention now there are only 2 suppliers who can offer a truly integrated control & Safety System (ICSS), ABB (800xA) and Siemens (PCS7).
