To make PLC (Programmable Logic Controller) controller more durable, the following aspects can be considered and implemented:

1.Choose the right PLC model and specification

Select according to application requirements:

Make sure that the model and specification of the selected PLC meet the requirements of the specific application, and avoid over-design or under-design.

Brand and quality:

Choose well-known brands and high-quality products, which usually have better durability and reliability.

2.Reasonable installation and layout

Environmental temperature and humidity:

Ensure that the temperature of the PLC installation environment is between 0-55 degrees Celsius and the humidity is less than 85%. Avoid installation in places with high temperature, high humidity, direct sunlight or near heat sources.

Ventilation and heat dissipation:

There should be sufficient ventilation space around the PLC to avoid high calorific value components close to the PLC. If necessary, heat dissipation equipment can be installed.

Avoid pollutants:

Keep away from pollutants such as dust, dust, corrosive gases, etc. If it must be used in these environments, sealing and filtering measures should be taken.

3.Correct wiring and configuration

Follow the instructions:

Strictly follow the installation and use instructions of the PLC to ensure correct wiring and configuration.

Power supply and grounding:

Use a suitable power supply and ensure that the power supply is stable and reliable.

PLC should be grounded separately, the grounding resistance should be less than 100Ω, and the cross-section of the grounding wire should be greater than 2mm².

Cables and wiring:

Power lines, I/O lines, control lines, etc. should be wired separately to avoid mutual interference.

Use crimping terminals or single twisted wires to connect PLC terminals, and avoid using multi-strand twisted wires.

4.Regular maintenance and care

Cleaning work:

Regularly clean PLC equipment to avoid the accumulation of pollutants such as dust and prevent corrosion of circuit boards.

Check cable connections:

Regularly check the quality of cable connections to ensure good connections, no looseness, no short circuits, etc.

Replace batteries:

Regularly check the backup batteries in PLC equipment and replace aging batteries in time to avoid data loss.

Software and program checks:

Regularly check PLC programs to ensure their correctness and loopholes.

At the same time, regularly back up PLC programs and data to prevent data loss due to unexpected situations.

5.Safety protection and troubleshooting

Safety protection:

Ensure the electrical safety of PLC and related equipment, including correct grounding, appropriate electrical insulation and protective measures.

Set up safety equipment such as emergency stop buttons and safety doors.

Fault handling:

Establish appropriate troubleshooting and diagnostic mechanisms to promptly discover and solve problems through alarms, log records, remote monitoring and other means.

For common types of faults, such as power failure, input and output failures, program loss or abnormal operation, countermeasures should be prepared in advance.

6.Continuous updates and upgrades

Technical updates:

Pay attention to the development of PLC technology, and keep abreast of new technologies and new products.

System upgrades:

According to changes in application requirements, make necessary upgrades and modifications to the PLC system to improve the performance and durability of the system.
