@@RemixProf In your experience Sir what is the main difference of Dcs and Scada..

I’m no expert and far from it, but I happen to work in Industrial Automations Controls Systems and work for an OEM who supplies major Plant Package Water Systems to Energy Sector clients, mostly Power Plants. The difference between both SCADA & DCS used to confuse me a lot. So much so I use them interchangeably. Yet, I kinda knew some differences just harder to explain and in that SCADA was more like a mishmash of systems all controlling everything unlike a DCS with an overall unified control system. Still even when a plant has a DCS, it still has SCADA systems of sorts that operate in the field with a server and maybe the other client workstation in the DCS Room but not connected to their actual DCS. Sometimes it’s connected, sometimes it’s not from our PP customers. So customers kinda have both. It required more work though to Modbus connect it all data wise to their DCS. However, I now understand some real differences via the video. Weintek I think it’s called is another cheaper HMI similar to Redlion. Good stuff though. RealPars rules. Jabs at needing more Allen Bradley content here and on the RealPars site.

Seems like if you have multiple independent process working unified for a goal (example a poultry processing facility using Ishida, Sandiacre, Modicon, Allen Bradley which all have an equal hierarchy of control) a SCADA system is the way to go. Verses, if you have a facility that uses mainly one control system ( a power plant that has one system with main hierarchy, while able to utilize subsystems with lower hierarchies ), a DCS is they way to go.

Great Thanks for Your Job!

Love your videos, very interesting. There are circumstances where the cost of a DCS software such as PCS7 will cost more than Step7/WinCC to perform the same tasks, (at Siemens) I was working on the data analytics side helping an integrator who had installed a brewery control system, the decision (by the integrator) to go with S7-1500 + ET200s was based on software cost rather than anything else. They did already have their own libraries to run this however. I believe that in TIA at least, PLC tags can easily be dragged across onto a HMI, and easily searched/selected if needed. No need to manually export and import the tag lists that is handled automatically.

Also there is an aspect regarding the geographical area of the process to supervise and control. SCADA philosophy is more appropiate for macro control of a process distribuited geographically, like a Power Utility System, where generation, tramsmission and distribution facilities needs to be managed and cordinated as a whole.

Expected to mention the redundancy capability for the dcs as the main advantage for safety

@plchacker

6 ай бұрын

Redundancy is available with AB CLX (ControlLogix.) In fact CLX offers many of the same features that the video points out as DCS specific. This focused on Siemens which in my personal opinion is far behind in technology. Siemens uses slower 16 bit processors, slower networks and their on-line capability is very limited. The programming style is very different and uses extremely limited timer functions among other irritating restrictions. If you move to Honeywell, ABB or Delta-V DCS, then certainly the differences start to appear. True DCS (Delta-V for example) is far more robust with many added safety features not found in the PLC world. One example is intrinsically safe I/O systems. Another is the built in database functionality. Safety PLC's are a different world altogether. They have comparably simple tasks and are very redundant. They are also often used in conjunction with DCS systems to provide an extra layer of safety. The differences between Allen Bradley and Siemens is rooted in the initial goals of design. Allen Bradley gets its roots from the original PLC team (Modicon) and kept the idea that electricians should be able to troubleshoot systems easily. The Siemens folks decided that this should be restricted to engineers and dedicated programmers. Initially, Siemens was focused on statement list programming, which is faster on the keyboard, but troublesome when you get online. Allen Bradley perfected ladder logic right from the beginning. They also focused on online capability and memory management. Both are very capable and will solve most manufacturing controls issues. I have lived and worked in both worlds. DCS is primarily for process controls. While it does have discrete capability, it is slow and not as flexible in the discrete world. For analog signals though DCS is difficult to beat. Even with the advanced capabilities of AB CLX, DCS still shines in the petrol-chemical and power generation worlds.

Very good tutorial, unfortunately not all aspects of a DCS system are mentioned. An PLC system is likely used for a dedicated application where the DCS is more used for controlling a whole plant. In most of the plants they use both at the same time, connected together (SCADA, Hardwired, OPC, Modbus...). Where the DCS is on top of the PLS system. And if the installation was good they can still work independed in case the PLC or the DCS got a problem. Thats why most PLS even they are connected to a DCS have got an HMI panel.

@realpars

Жыл бұрын

This was the case in the early 2000s, but with the introduction of bigger and faster processors, there is little difference in speed between DCS, PLC, and the supervisory SCADA systems. In reality speeds of processors are faster than the requirements for data updates. Most DCS systems update values from 4 to 10 times per second. This is on par with modern SCADA systems, so the differences are less pronounced than 10 - 15 years ago.

You must add Mitsubishi

Can HMIs still be utilised in a DCS system? This graphical interface that is mentioned that is integrated into the system, does it contain HMIs or is it similar hardware with touch screen capabilities?

@realpars

2 жыл бұрын

HMI, referring to the terminal used to display operator graphics, is used in DCS, SCADA, PLC, and hybrid systems. For DCS systems, the software used to generate screens and execute them is typically integrated into the DCS system, and likely is part of a single software suite. For the other systems, the HMI configuration and server applications may be stand-alone, with communication connections to the controllers to access process data.

SCADA is centralized and DCS is distributed, one of the main things in the video is wrong 😑 SCADA systems are highly distributed systems used to control geographically dispersed assets, often scattered over thousands of square kilometers, where centralized data acquisition and control are critical to system operation. They are used in distribution systems such as water distribution and wastewater collection systems, oil and natural gas pipelines, electrical power grids, and railway transportation systems. A SCADA control center performs centralized monitoring and control for field sites over long- distance communications networks, including monitoring alarms and processing status data. Based on information received from remote stations, automated or operator-driven supervisory commands can be pushed to remote station control devices, which are often referred to as field devices. Field devices control local operations such as opening and closing valves and breakers, collecting data from sensor systems, and monitoring the local environment for alarm conditions. DCS are used to control industrial processes such as electric power generation, oil refineries, water and wastewater treatment, and chemical, food, and automotive production. DCS are integrated as a control architecture containing a supervisory level of control overseeing multiple, integrated sub-systems that are responsible for controlling the details of a localized process. Product and process control are usually achieved by deploying feed back or feed forward control loops whereby key product and/or process conditions are automatically maintained around a desired set point. To accomplish the desired product and/or process tolerance around a specified set point, specific PLCs are employed in the field and proportional, integral, and/or derivative settings on the PLC are tuned to provide the desired tolerance as well as the rate of self-correction during process upsets. DCS are used extensively in process-based industries.

Thank you for your comments. The point about distributed components was made clear from 1:00 to 1:30 in the video and SCADA clearly is designed to operate across multiple locations. To be honest, the terms SCADA DCS are becoming "worn", as many hybrid systems have com onto the market that look and act a little like each type of system. Originally, the "D" in DCS, or distributed, referred to the separation of I/O and controller hardware within the same local system. Per the "classic" definition, the video is correct. Both types of systems are becoming closer in function, as explained in the video, and also in hardware. The true differences lie in two areas: DCS systems still have more of a reliance on a single vendor for hardware, and DCS systems tend to be configured from common component libraries and tag databases that are shared among components in the system.

Let me save you a video. DCS is one OEM products. SCADA system, is many OEM products that need scada s/w to synchronise them.

is DCS programming the same as PLC programming?

@realpars

4 жыл бұрын

No. DCS systems are partially configured and partially "programmed". The tags, I/O, loops and alarms are typically all configured using wizards, tables, and menus. Device and control loop logic is typically provided as pre-configured internal blocks where the "programmer" simply makes connections between the tag table and these blocks. In PLC programming, more choices are available for creating logic, such as ladder logic, structured text and function blocks. While there are many items like tag tables that are configured much the same as in a DCS, there is more "programming" effort in the PLC environment, but there is somewhat more flexibility as well compared to a DCS. DCS systems are more efficient for process that are heavy in analog inputs and outputs. PLC systems are more efficient for process that are heavy in digital inputs and outputs.

After 15 years in control systems. Odysseus has no safer than SIL 3 rated PLC. In fact with the lag time of a DCS I would say it's less safe.

hi, you have forgotten, some dcs systems completely open to all forms of communication, but above all in a ring with intersected servers, with an intuitive man-machine interface, giving the company the possibility to remain active and productive 365 days a year, the ABB system six system and the new one, but not least the yokogawa system, with modular redundancies, which can take on parts of the ring out of use without causing the system to stop, keeping it ALWAYS efficient and above all PRODUCTIVE THE SITE, unlike an independent system without redundancy, like the SCADA
