DCS system maintenance
Thread Content
I’m just starting to work with DCS systems. What aspects should be taken into consideration for routine hardware maintenance, and what tasks need to be carried out? This post was last edited by wopale3 on 2009-4-15 19:45]
Use search more often, my new friend. There are many topics like this
1. Be careful to discharge static electricity, as static on the body can damage the cards. The temperature and humidity in the server room can be controlled using static discharge columns or anti-static wristbands. Ensure good ventilation and be careful to prevent dust. 3. Regularly measure the grounding resistance of the system. 4. Have measures in place to prevent small animals (such as mouse traps and poison). 5. Mobile phones should be turned off inside the machine room to avoid interference. 6. It is necessary to know the function of various indicator lights on the card devices, as well as what their status is in case of a fault. 7. Keep proper records of spare parts and system maintenance
Be careful of small animals; rats have once made nests in our cabinets, damaging the circuit boards. Under no circumstances should food be taken to the area where the cabinets are located.
The upstairs area is so cute: lol. It’s also important to have spare parts ready; keep a few spare components that are used frequently and prone to breaking, such as AI/AO cards, as they tend to fail more often. Otherwise, if those components get damaged and there are no replacements, it will affect production.
The most important things are to control the temperature of the indoor air conditioning, monitor the operation of the fans inside the cabinets, and take measures to prevent rats. Actually, everything was pretty well covered on the 3rd floor
Make sure to check the cooling of the operation station and cabinets； Regularly perform backups and keep records ； View alarms and history, especially by analyzing the alarms; many accidents can be anticipated from them.
Check the system alarms daily to verify whether there are any hardware failures in the control station and operation station
It is recommended that you familiarize yourself with the “three regulations” for your position: safety operation procedures； Equipment Operating Procedures ； Find the equipment maintenance and repair procedures to study* and you’ll know how to do it!
Search for information on the forum based on your DCS model. If it’s from abroad and the manufacturer doesn’t provide Chinese documentation, you can look for such documentation online. First, gain a basic understanding of your own system: become familiar with the hardware and system architecture, as well as the software. Master the basic configuration and hardware maintenance as well. After that, I read the English documentation to gain a deeper understanding, because when major problems arise, it is often necessary to consult the original manufacturer’s materials.
For routine inspections, it is necessary to create a flowchart that outlines what needs to be done first and what later, so as to develop this habit and make it a regular practice. First: Check the working environment: cleanliness, temperature, humidity, and rodent prevention measures. Second: Review the alarm records, analyze the causes, count the frequency of occurrences, and prepare treatment plans and necessary materials. Third: Inspect the cabinets: focus on ventilation and abnormal noises; check the condition and ventilation of UPS cabinets, power supply cabinets, and communication cabinets, as well as the DCS cabinets.
What was said upstairs is right; room temperature control is very important
1. The temperature and humidity in the server room are very important; pay attention to ventilation regularly. 2. Pay attention to the issue of static electricity grounding
