In all PLC systems, the PLC rack or chassis forms the most important module and acts as a backbone to the system. PLCs are available in different shapes and sizes. When more complex control systems are involved, it requires larger PLC racks. Small-sized PLC is equipped with a fixed I/O pin configuration.

Large PLC systems consist of a rack into which circuit “cards” are plugged. These cards include processors, input and output (I/O) points, communications ports, and other functions necessary to the operation of a PLC system. Such “modular” PLCs may be configured differently according to the specific needs of the application.

Decimal System Various number systems are used by PLCs. All number systems • Describe important number systems and data types used by Siemens PLCs. • Identify the major components of a PLC and describe their functions. • Describe the parts of a typical PLC scan. • Define the terms “functional safety” and “failsafe.” • Identify the key features of S7-1200 standard and failsafe CPU models.

iĢ güvenliği standardı ve bağlantı tekniğine uygun. The typical PLC system is like any other computer system that consists of various hardware components such as the CPU, programming devices as well as PLC-based process controller is a process control system which has the base of SYSMAC SC/CJ series. It can be adopted for both loop control which controls A programmable logic controller (PLC) is and industrial computer used to control and automate complex systems. Programmable logic controllers are a relatively m0 .

Sometimes binary digits are used individually and sometimes they are used to represent numerical values.

PLC-based process controller is a process control system which has the base of SYSMAC SC/CJ series. It can be adopted for both loop control which controls

At the same time the new control system allows new safety precautions as a two hand control to be implemented. to easily adapt to any PLC encountered.

A PLC is a computer designed to work in an industrial environment PLCs are equipped with special input/output interfaces PLCs are programmed using a control programming language. The PLC signals are transmitted to the active or passive components via 40-pole or 10-pole pre-assembled control cables. The PLC signals are converted either: • in double-word form via a flat-strip connection or • byte-for-byte via 10-pole flat-strip connections System cabling The basic principle is to connect PLC-specific front adapters to 22.2.1 Analog Inputs With a PLC-5 22.9 22.3 ANALOG OUTPUTS 22.13 22.3.1 Analog Outputs With A PLC-5 22.16 22.3.2 Pulse Width Modulation (PWM) Outputs 22.18 22.3.3 Shielding 22.20 22.4 DESIGN CASES 22.22 22.4.1 Process Monitor 22.22 22.5 SUMMARY 22.22 22.6 PRACTICE PROBLEMS 22.23 22.7 PRACTICE PROBLEM SOLUTIONS 22.24 22.8 ASSIGNMENT PROBLEMS 22 Large PLC systems consist of a rack into which circuit “cards” are plugged.
