OIL AND GAS PLC FUNDAMENTALS TRAINING ADNOC
PURPOSE OF THE OIL AND GAS PLC FUNDAMENTALS TRAINING PDF
The student will be able to: Describe how PLC systems vary from the more traditional relay systems.
Describe how a basic PLC ladder diagram works.
Describe the purpose of the Allen-Bradley PLC's parts.
Explain the three fundamental PLC systems using a block diagram:
A single PLC.
Two redundant PLCs
3. PLC with triple redundancy
Give instances where the various PLC types might be employed.
PLC hardware is made by a variety of companies. They all produce their diagrams according to various standards and using various data transmission techniques.
This indicates that ADNOC and the operating businesses do not combine several PLC system types. When managing a process, PLC systems cannot be mixed. Some of the PLC systems utilised in the field are:
Ladder diagrams display the PLC system's operational flow. They describe in detail what occurs when the system is initiated, stopped, or used in an emergency. From top to bottom of the ladder, you descend.
