The given text describes a "jest industrijski računalni sustav za uporabu u industrijskom okolišu s programabilnom memorijom za internu pohranu u primjeni orijentiranih upravljačkih naredbi kod implementiranja specifičnih funkcija kao što su npr. logičko upravljanje, slijedno upravljanje, funkcije odbrojavanja, funkcije brojenja i aritmetičke funkcije." This is the description of a PLC (Programmable Logic Controller), which is an industrial computer system used for controlling specific functions in an industrial environment, such as logical control, sequential control, counting functions, and arithmetic functions.

The correct answer is "Programiranje PLC-a vrši se jezikom ljestvičastih logičkih dijagrama (engl. ladder diagram)". This means that programming of PLCs is done using ladder logic diagrams. Ladder logic is a graphical programming language that uses ladder-like diagrams to represent the logical functions and control sequences of a PLC program. It is widely used in industrial automation for programming and controlling PLCs.

PLC stands for Programmable Logic Controller, which is a device used in industrial automation systems to control and monitor various processes. It is a computer-based control system that uses programmable memory to store instructions and execute specific functions. PLCs are widely used in manufacturing industries to automate tasks, improve efficiency, and ensure safety. They can be programmed to perform a wide range of functions, such as controlling machinery, collecting data, and communicating with other devices. Therefore, the correct answer is Programmable Logic Controller.

PLC (Programmable Logic Controller) je vrsta računalnog sustava koji se koristi za automatizaciju industrijskih procesa. Ova izjava tvrdi da je PLC izuzetno otporan na različite pogonske uvjete rada kao što su prašina, vlaga, visoka temperatura, vibracije i drugi mehanički utjecaji. Ova tvrdnja je točna jer su PLC uređaji posebno dizajnirani da budu izdržljivi i pouzdani u industrijskim okruženjima gdje su prisutni različiti štetni uvjeti.

The correct answer is "programski ciklus (engl. Scan cycle)". A program PLC (Programmable Logic Controller) executes in a continuous loop called a scan cycle. During each scan cycle, the PLC reads inputs, executes the program logic, and updates outputs. This cycle repeats continuously to ensure real-time control and monitoring of the system. The term "scan cycle" is commonly used in the field of PLC programming to describe this repetitive process.

The correct answer is "samostalna (engl. single-ended)". In this type of PLC application, one PLC controls one process and does not communicate with other computers or PLC devices. This means that it operates independently and does not require any external input or coordination from other systems.

The correct answer is "modularni PLC sklopovi" and "kompaktni PLC sklopovi". These are the two basic construction methods for PLC circuits. Modular PLC circuits are built using separate modules that can be added or removed as needed, allowing for flexibility and customization. Compact PLC circuits, on the other hand, are built as a single unit with all the necessary components integrated into one compact design. Both methods have their advantages and are commonly used in different applications depending on the specific requirements and constraints.

The correct answer is "napajanje." Napajanje refers to the power supply, which provides a direct current voltage for all the modules connected to the CPU. It is responsible for supplying the necessary power to ensure proper functioning of the components.

The given answer is "CPU". The explanation is that a PLC consists of a microprocessor that executes a program and manages communication between modules. The microprocessor requires memory to store the results of logical operations it performs. CPU stands for Central Processing Unit, which is the main component of a computer or PLC that carries out the instructions of a program by performing basic arithmetic, logical, control, and input/output operations.

In this question, the correct answer is "višeprogramska (engl. multitask)". This answer is the most appropriate because it refers to a PLC application where one PLC controls multiple processes. The term "multitask" implies that the PLC is capable of performing multiple tasks simultaneously or in parallel. This is a common feature in advanced PLC systems where the controller can handle multiple inputs, outputs, and processes concurrently, improving efficiency and flexibility in industrial automation.

The correct answer is "nadzorna (engl. control management)". In this type of PLC application, one PLC is responsible for controlling multiple other PLCs. This suggests that the main purpose of this category is to manage and oversee the control of multiple PLCs, ensuring they work together effectively.

The correct answer is "ulazni prilagodni stupanj" which translates to "input adaptation stage" in English. This stage converts the level of real logic into a level of logic that corresponds to the CPU unit. It is responsible for adapting the input signals to a format that can be understood and processed by the CPU.

The correct answer is "ulazni modul". This is because an "ulazni modul" is a device that receives signals from input devices in a PLC (Programmable Logic Controller) system. It acts as an interface between the input devices and the PLC, allowing the PLC to process and respond to the signals received.

The correct answer is "izlazni modul". In this question, the term "Dio PLC" refers to a part of a PLC (Programmable Logic Controller) system. The question asks for the name of the module that is used to send binary signals to output devices. An "izlazni modul" (output module) is the component responsible for sending signals from the PLC to the output devices, making it the correct answer.

The statement says that in systems with a large number of PLC units, the power supply of the PLCs is used to power external devices and they do not need their own power supply. The correct answer is "Netočno" (False) because this statement is incorrect. In systems with a large number of PLC units, each PLC unit typically requires its own power supply to function properly, and the power supply of the PLCs is not used to power external devices.

Modular PLC circuits have the characteristic of having a larger number of modules within a mechanical frame (rack), allowing for easy system expansion. They also have a specific number of slots in the frame, ranging from 4 to 16.

Compact PLC modules have the following characteristics: they cannot be expanded, they are independent and closed with a fixed number of inputs/outputs, they have power supply, CPU, and I/O modules in one housing, they have a larger number of modules within a mechanical frame (rack), easy system expansion, and they have a number of slots in the frame ranging from 4 to 16.

The correct answer is that an open architecture PLC can easily connect with devices and programs from other manufacturers, uses components that adhere to an agreed standard, and can be used to control complex processes with multiple connected PLC devices. This means that the PLC is not limited to a specific manufacturer or proprietary technology, allowing for flexibility and interoperability with other systems. It also enables the use of standardized components, simplifying integration and maintenance. Additionally, the open architecture allows for scalability and the ability to control interconnected processes, enhancing the PLC's capabilities.

The given answer lists the possible output devices for a PLC (Programmable Logic Controller). These devices include relays, lights, valves, heaters, and switches. PLCs are commonly used in industrial automation to control various processes, and these output devices are used to interact with the physical world based on the programmed logic in the PLC.

The communication part of a PLC enables communication with other PLC devices, various sensors, modem connection, operator panels, sending programs to the PLC, and communication with a superior programmer or computer where the control program is written.

The function of the U/I module is to convert the digital signal from a sensor into a numerical value of 0 or 1 and store it as a 1-bit in memory. It also reads the value of a bit in memory and converts it into a binary signal that is sent to an actuator.

PLC (Programmable Logic Controller) je specijalno industrijsko računalo koje ima mogućnost komunikacije sa drugim PLC-ovima, računalima i drugim uređajima. On prima signale sa procesa i na osnovu tih signala vrši upravljanje određenim izlaznim uređajima na procesu. PLC također služi za mjerenje procesnih veličina.
