Disadvantages of PLCs
- Once a PLC system is installed and programmed , it is difficult modify the control logic .
- It requires regular maintenance to ensure proper operation ,otherwise it increases operational costs and downtime .
- PLCs are having limited processing power and memory capacity that may restrict the complexity and performance of control algorithms .
- PLCs programs are difficult to develop as well as for debugging.
- Initial cost of PLCs is high that includes hardware , software and programming services .
- These are designed for use in industrial environments with specific temperature , humidity and vibration requirements .
- Fixed circuit operations.
What are the different types of PLC ?
PLCs focus on implementing logic and switching operations to efficiently control systems. It is used to control various types of machines or processes through digital or analog input/output.
