PLC : \nThe memory unit of a PLC is the registry where the programs are stored. The fundamental unit of memory is the word. Words are made up of bits. A bit is a single piece of data. It contains information on only two states (ON/OFF or YES/NO). Longer words contain more information within. Programs are combination of words that produce control logic.\nTo operate the PLC system there is a need for it to access the data to be processed and instructions, that is, the program, which informs it how the data is to be processed. Both are stored in the PLC memory for access during processing.\nBASIC PLC HARDWARE ARCHITECTURE\n \nThe PLC consists of the following components:\n• The processor module (CPU)\n• Memory\n• The power supply,\n• and the Input/output modules.\n\n\nPLC MEMORY : \nThe memory unit of a PLC is the registry where the programs are stored. The fundamental unit of memory is the word. Words are made up of bits. A bit is a single piece of data. It contains information on only two states (ON/OFF or YES/NO). Longer words contain more information within. Programs are combination of words that produce control logic.\nTo operate the PLC system there is a need for it to access the data to be processed and instructions, that is, the program, which informs it how the data is to be processed. Both are stored in the PLC memory for access during processing.\nROM and RAM are the most common types of memory used in PLCs.\nREAD ONLY MEMORY (ROM): stores programs and data and cannot be changed after the memory chip has been manufactured. ROM memory is non-volatile, meaning that its contents will not be lost if power is lost. ROM is used by the PLC for the operating system.\nRANDOM ACCESS MEMORY (RAM): is designed so that information can be written into or read from the memory. RAM is used as a temporary storage area of data that may need to be quickly changed. RAM is volatile, meaning that the data stored in RAM will be lost if power is lost. A battery backup is required to avoid losing data in the event of a power loss\n\nINPUT OUTPUT MODULES : \n I/O modules physically connect to field devices, that is they provides the interface between the system and the outside world, allowing for connections to be made through input/output channels to input devices. Since there are different types of input and output devices, the process determines the type of input or output module selected, digital or analog.\nInput gives the controller real time status of variable in the form of real world signals. These variables can be analog, register or discrete. Typical analog inputs can be from thermocouples, RTDs, flow, pressure, and temperature transmitters. These inputs are transmitted over the I/O bus to the central processor unit after being converted into digital data. The input module is entrusted with the operation of converting electrical signals flowing in from input field devices like push buttons to electrical signals that the PLC can understand. Examples of input modules include limit switches, proximity switches and push buttons, photo sensors, and temperature sensors,motion control or high-speed counters.\n
PLC. Ladder yöntemiyle yazılan PLC programlarında bir çıkış doğrudan enerji kaynağına bağlanamaz. Çıkıştan önce en az bir tane normalde açık ya da normalde kapalı kontak bulunmalıdır. LD Komutu: Normalde açık bir kontak ile hat ( komut bloğu) başlatılmasını sağlar.
