What to do if the DCS computer goes black?
Contact the relevant personnel to restart the computer; meanwhile, monitoring can be carried out through other screens or on-site instruments.
Fails of the upper-level computer generally do not affect the operation of the lower-level units. For systems that do not require frequent adjustments, a short period of downtime of the upper-level computer will not impact production; another computer can be used to take its place. Additionally, be sure to set the option to automatically turn off the display in the advanced power management of the host computer to \"Never\".
Contact all personnel on duty, ensure proper monitoring at the site, and then check for computer faults, aiming to get the computer up and running in the shortest possible time.
I think what the original poster is asking is how to handle the system when DCS goes black, right? Hehe, in my opinion, it’s necessary to handle each situation on a case-by-case basis. First, contact the dispatch and monitoring staff immediately; if it can be resolved within a very short time, then handling it according to operational experience is appropriate. At least, overpressure or overheating should be avoided, and the specific procedures to follow depend on the particular role involved. If it cannot be resolved in a short time, it is best to inform the dispatcher to stop the machine immediately to avoid safety accidents.
Also, it is recommended that the owner install a relay in the instrument system. In case of an emergency occurs. :lol
Most operator workstations can be operated by multiple users simultaneously, and it’s not a big problem to temporarily shut down a workstation that is having issues. The control functions are not located in the operator workstation; it merely provides an operation interface. However, when configuring operation permissions for workstations, it is necessary to consider the situation in case a single workstation fails, so that another workstation can take over its functions. An important aspect of running critical tasks is that there is usually a redundant fault-tolerance design, so any faulty components will be automatically disconnected. It can be repaired in time at this point.
It’s not a big problem if a device goes black; just contact an instrument technician to come and restart it. If the screen goes completely black, that’s a problem; it could be due to an issue with the power supply for the instruments, or it might be caused by voltage fluctuations. Operators need to be familiar with the DCS emergency procedures, restart the system immediately, and at the same time contact the instrument technicians to handle the situation, while also preparing for an emergency shutdown. That’s a good question; the plans in this area need to be improved as soon as possible!
