4 Early Control of Plants  Many operators  Locally Mounted Devices  Large Indicating instruments and valves

5 Pneumatic Analogue 4 -20 mA Hybrid (Smart) Fieldbus 1940 196019802000 At First : Evolution Of Signal Transmission technology Vendor Proprietary Communication Protocols Uniform Interoperable Communication Protocols

6 196019802000 DCS DDCFCS Time PLC Next: Evolution Of control systems

7  Pneumatic Signal Transmission  3-15 psi signals  Field data gathered in a central control room  Provision of compressed air Pneumatic Control Systems

8 This was the beginning of the concept of bringing the plant to the operator rather than requiring the operator to go out into the plant.

9 Following World War II, electronic controls became more rugged for industrial environments. More measurements becoming possible because the cost of sensors was coming down. More Sophisticated Control Rooms

10 The size of controllers was smaller, so more of them could fit on a panel, in a smaller area. All of this led to a more complex control room.

11 Central Mainframe Computer Control As changes in technology brought down the price of computers, their use became more common in large and more complex facilities. This allowed the single centralized control room to develop further.

12  Advantages:  Sophisticated Control  Flexible Control  Data Acquisition Alarm  Disadvantages:  Computer reliability  Redundant computer or controllers  Writing complex and extensive  HMI required high-level operators  Expensive

13 Distributed Control The distributed process architecture permits a functional distribution of the tasks among many processors, reducing the of everything failing at once. The central control room view of plant operation give the operator a single window into the process.

14 A DCS system has limited resources. Each transmitter and valve, or each loop that is added to a DCS system consumes some I/Os and processing capacity. So, generally a DCS package is designed with some spare resources for future expansions. However, when these are over, another costly investment would be necessary for an expansion.

15 Programmable Logic Controllers (PLCs) PLCs were designed for use in factory automation functions when the operation required many rapid,repeatable operations as on most assembly lines.

16 Today’s PLSc can be more efficient than ever before in performing sequencing, regulatory and interlocking operations. Real-time control for interlocking motors and related equipment has become very practical within PLCs used in the process control world.

17 PC-based Controllers The next generation of controllers in factory automation was PC-based controllers. Although in the mid-1990’s there was steel the need for “mission-critical” robustness in function- specific hardware, the trend was toward “off-the shell” hardware and a way from proprietary systems. New generation PCs are getting heavily involved in direct control, i.e., the handling of real inputs and the use of control algorisms to provide control outputs directly back to the machine or process.

18 The factors behind success of PC based technology Processing power Windows OS Low cost Modular architecture and easy “application specific configuration” Single network layer Flexibility in connectivity

47 How to Automate

48 PLC

49  PLC was introduced in 1960’s and rapidly gained popularity in the area of sequential control application as a “digital electronic device that uses a programming means to store instructions and implement specific functions such as a logic sequence, timing counting and algorithms to control machines and process’.

50  PLCs perform well sequential tasks such as machine control and are available in different classes and scales, ranging from 30 point input/output and 1 k RAM capacity to large scale versions having input/output capacity of 500 and 64 k RAM.

51 Powerful advantages of PLCs: F Excellent logic-handling capabilities F Very fast, with the ability to detect a malfunction within a few milliseconds F Very cost effective F Can withstand rough environment F Highly reliable F Offer high level of flexibility and expandability F They are usually very compact

52 The main drawback of PLCs: F No ability to predict response time F Limited in its continuous loop control capabilities F Need for host computer or personal computer to interface with process controls F Batch control software is typically not available for the process control F Available user interfaces do not always have the capability of those provided with distributed controls F Requiring the services and costs of an independent integrator

59 DCS has since dominated the industry where continuous control has been the main concern. There is now variety of choices to fit particular applications. These cover :

60  PLC based DCSs which consist of network of PLCs used to perform similar functions as a conventional DCS, and reapplied when there is a need for more programmable functionality such as material handling and packaging.  Hybrid DCSs, being combinations of above, used in order to perform process and sequential control  The conventional DSCs that the pure “process only” control systems and come in small, medium and large-scale versions in terms of their input/output handling and control capacity.

76 Questions to think about it before developing a Fiedlbus product : “Which kind of End-Product are you looking for?” “How am I looking to develop this product?” “How much time and resources am I able to provide?“ “Which parts could I develop in-house? If so, how can I develop it?”

77 If you look to a typical Foundation Fieldbus installation, your main parts are Power Supplies, Power Supplies Impedance, Bus Terminators, Devices and cable. All of them are simple equipment, connected in parallel.

79 As many as 16 loop drawings Do you know? 1 fieldbus segment drawing

80 Fieldbus Cost Benefits “We used to estimate installation costs at two times the cost of hardware. With fieldbus, our installation costs were less than one quarter of the cost of hardware. As a result, we did not have to capitalize our installation costs; we were able to pay for them on our maintenance budget.…” Major Pharmaceutical Company

81 “To add a traditional well with hard wiring takes about 6 weeks…a month to 6 weeks, by the time you go through all of the drawings and all of the updates. To do a fieldbus, it would take a pretty green person…I’d give him a day, but I could do it in 2-3 hours.” Jim Cameron, Alaska Anvil Fieldbus Cost Benefits
