The Main Difference Between PLC and DCS

The Main Difference Between PLC and DCS

Programmable Logic Controllers (PLC)

Programmable Logic Controllers (PLC) were first created to serve the automobile industry, and the first programmable logic controller project was developed in 1968 for General Motors to replace hard-wired relay systems with an electronic controller.

Programmable Logic Controllers, are frequently used to synchronize the flow of inputs from sensors (Physical) and events with the flow of outputs to actuators and events. This leads to precisely controlled actions that permit a tight control of almost any industrial process.

This is actually a control device that consists of a programmable microprocessor, and is programmed using a specialized computer language. Before, a programmable logic controller would have been programmed in ladder logic, which is similar to a schematic of relay logic. A modern programmabl logic controller is usually programmed in any one of several languages, ranging from ladder logic to Basic or C. Typically, the program is written in a development environment on a personal computer (PC), and then is downloaded onto the programmable logic controller directly through a cable connection. The program is stored in the programmable logic controller in non-volatile memory.

Programmable logic controllers contain a variable number of Input/Output (I/O) ports, and are typically Reduced Instruction Set Computer (RISC) based. They are designed for real-time use, and often must withstand harsh environments on the shop floor. The programmable logic controller circuitry monitors the status of multiple sensor inputs, which control output actuators, which may be things like motor starters, solenoids, lights and displays, or valves.

Digital signals yield an on or off signal, which the programmable logic controller sees as Boolean values. Analog signals may also be used, from devices such as volume controls, and these analog signals are seen by the programmable logic controller as floating point values.

There are several different types of interfaces that are used when people need to interact with the programmable logic controller to configure it or work with it. This may take the form of simple lights or switches or text displays, or for more complex systems, a computer of Web interface on a computer running a Supervisory Control and Data Acquisition (SCADA) system.


Distributed Control System (DCS)

Distributed Control System (DCS) is a system of dividing plant or process control into several areas of responsibility, each managed by its own controller, with the whole system connected to form a single entity, usually by means of communication buses.

Distributed Control System (DCS) refers to a control system usually of a manufacturing system, process or any kind of dynamic system, in which the controller elements are not central in location (like the brain) but are distributed throughout the system with each component sub-system controlled by one or more controllers. The entire system of controllers is connected by networks for communication and monitoring.

A DCS typically uses custom designed processors as controllers and uses both proprietary interconnections and Communications protocol for communication. Input & output modules form component parts of the DCS. The processor receives information from input modules and sends information to output modules. The input modules receive information from input instruments in the process (a.k.a. field) and transmit instructions to the output instruments in the field. Computer buses or electrical buses connect the processor and modules through multiplexer or demultiplexers. Buses also connect the distributed controllers with the central controller and finally to the Human-Machine Interface (HMI) or control consoles


What is the difference between PLC and DCS?

The main difference between Programmable Logic Controller (PLC) and Distributed Control System (DCS) are:

The number of I/O in the system. DCS is dealing with very large no. of I/O with less cost. also DCS comes with it's SCADA always. if DCS stopped, all system is stopped. if the system has less No. of I/O, then PLC is better from cost view. Also SCADA is optional. if system is controlled by no of PLC. if PLC is down. others continue working Normally. Historical, main difference was that DCS deal with Analogue signals but PLC deal with Discrete digital system. Now DCS has Digital Modules and PLC has Analogue modules.

Besides, PLC has a processor and input and output cards (I/O card could be digital and/ or analog) Processor has the software - basis the input it receives from field devices it gives out the output commands to control devices of the field. DCS is a group of individual smart controllers (again having embedded software and connections with field devices) doing their specified operation (duty) but interconnected.

PLC Input Ouput (I/O)

PLC Input Ouput (I/O)

Input - Output I/O
PLC consists of a processor unit of I/O cards mounted in local racks. Early PLCs did tend tobe arranged like this, but in a large and scattered plant with this arrangement,all signals have to be brought back to some central point inexpensive multicore cables. It will also make commissioning and faultfinding rather difficult, as signals can only be monitored effectively ata point possibly some distance from the device being tested.In all bar the smallest and cheapest systems, PLC manufacturers therefore provide the ability to mount I/O racks remote from the processor, and link these racks with simple (and cheap) screened singlepair or fibre optic cable. Racks can then be mounted up to severalkilometres away from the processor.

There are many benefits from this. It obviously reduces cable costs asracks can be laid out local to the plant devices and only short multicorecable runs are needed. The long runs will only need the communication cables (which are cheap and only have a few cores to terminate at eachend) and hardwire safety signals.Less obviously, remote I/O allows complete units to be built, wired toa built-in rack, and tested offsite prior to delivery and installation. Thepulpit in Figure contains three remote racks, and connects to thecontrolling PLC mounted in a substation about 500m away, viaa remote I/O cable, plus a few power supplies and hardwire safetysignals. This allowed the pulpit to be built and tested before it arrivedon site. Similar ideas can be applied to any plant with I/O that needs tobe connected to a PLC.If remote I/O is used, provision should be made for a program terminalto be connected local to each rack. It negates most of the benefits if the designer can only monitor the operation from a central control roomseveral hundred metres from the plant. Fortunately, manufacturershave recognized this and most allow programming terminals to beconnected to the processor via similar screened twin cable.

PLC Output Cards
Output cards again require some form of isolation barrier to limit damage from the inevitable plant faults and also to stop electrical ‘noise’ corrupting the processor’s operations. Interference can be more of a problem on outputs because higher currents are being controlled by Computers and industrial

Computers and industrial control 25 the cards and the loads themselves are often inductive (e.g. solenoid and relay coils). There are two basic types of output card. Eight outputs are fed from a common supply, which originates local to the PLC cubicle (but separate from the supply to the PLC itself). This arrangement is the simplest and the cheapest to install. Each output has its own individual fuse protection on the card and a common circuit breaker. It is important to design the system so that a fault, say, on load 3 blows the fuse FS3 but does not trip the supply to the whole card, shutting down every output. This topic, called ‘discrimination’, is discussed further in Chapter. A PLC frequently has to drive outputs which have their own individual supplies.

A typical example is a motor control centre (MCC) where each starter has a separate internal 110-V supply derived from the 415-V bars. The card arrangement could not be used here without separate interposing relays (driven by the PLC with contacts into the MCC circuit). An isolated output card, has individual out-puts and protection and acts purely as a switch. This can be connected directly with any outside circuit. The disadvantage is that the card is more complicated (two connections per output) and safety becomes more involved. An eight-way isolated output card, for example, could have voltage on its terminals from eight different locations.

Relay outputs can be used (and do give the required isolation) but are not particularly common. A relay is an electromagnetic device with moving parts and hence a finite limited life. A purely electronic device will have greater reliability. Less obviously, though, a relay-driven inductive load can generate troublesome interference and lead to early contact failure. Optical isolation is again used to give the necessary separation between the plant and the PLC system. Diode D1 acts as a spike suppression diode to reduce the voltage spike encountered with inductive loads. The output state can be observed on LED1. If NPN transistors are used, a current sinking card can be made. AC output cards invariably use triacs, a typical circuit being. Triacs have the advantage that they turn off at zero current in the load, which eliminates the interference as an inductive load is turned off. If possible, all AC loads should be driven from triacs rather than relays.

An output card will have a limit to the current it can supply, usually set by the printed circuit board tracks rather than the output devices. An individual output current will be set for each output and a total overall output . Usually the total allowed for the card current is lower than the sum of the allowed individual outputs.

PLC Input Cards
Internally a computer usually operates at 5 V DC. The external devices (solenoids, motor starters, limit switches, etc.) operate at voltages up to 110 V AC. The mixing of these two voltages will cause severe and possibly irreparable damage to the PLC electronics. Less obvious problems can occur from electrical ‘noise’ introduced into the PLC from voltage spikes on signal lines, or from load currents flowing in AC neutral or DC return lines. Differences in earth potential between the PLC cubicle and outside plant can also cause problems.

The question of noise is discussed, but there are obviously very good reasons for separating the plant supplies from the PLC supplies with some form of electrical barrier. This ensures that the PLC cannot be adversely affected by anything happening on the plant. Even a cable fault putting 415 V AC onto a DC input would only damage the input card; the PLC itself (and the other cards in the system) would not suffer. This is achieved by optical isolators, a light-emitting diode and photo-electric transistor linked together.

Protection of the PLC from outside faults. The PLC supply L1/N1 is separate from the plant supply L2/N2 switch on. Because there are no electrical connections between the diode
and the transistor, very good electrical isolation (typically 1–4kV) is achieved. A DC input can be provided. When the push-button is pressed, current will flow through D1, causing TR1 to turn on, passing the signal to the PLC internal logic. Diode D2 is a light-emitting diode used as a fault-finding aid to show when the input signal is present. Such indicators are present on almost all PLC input and output cards. The resistor R sets the voltage range of the input. DC input cards are usually available for three voltage ranges: 5V (TTL), 12–24V, 24–50V. A possible AC input circuit. The bridge rectifier is used to convert the AC to full wave rectified DC. Resistor R2 and capacitor C1 act as a filter (of about 50ms time constant) to give a clean signal to the PLC logic. As before, a neon LP1 acts as an input signal indicator for fault finding, and resistor R1 sets the voltage range. The isolation barrier and monitoring LEDs can be clearly seen. This card handles eight inputs and could be connected to the outside world.
