DCS upgrade
Thread Content
Our DCS has been in use for nearly 4 years; now the manufacturer has introduced a newer version of DCS and recommended that we upgrade. Our old version of DCS has been working well so far, so I'm a little confused. Should I upgrade it? If you decide to upgrade, what preparations should you make?

If you use it well, it’s okay not to upgrade it temporarily. Ask the manufacturer. If it is to repair a DCS system software defect, the manufacturer should be responsible for upgrading it free of charge. If a hardware upgrade leads to a software upgrade, the software can be upgraded at the same time as long as the spare parts are used up or the hardware needs to be replaced. Software upgrades need to be carried out offline, requiring backup and informing process production to arrange shutdown time.
The elimination of replacement in the electronics industry is just like computers and TVs, which are always being updated. Do we have to change with them? Imagine if the company is yours, and you will know the answer. Recommended timing for evaluating equipment updates and upgrades in the enterprise 1. The failure rate of the current equipment 2. The ratio of the current acquisition cost and maintenance cost of the equipment. In principle, it can be recovered better in 5 years 3. The difficulty of purchasing spare parts for equipment maintenance 4. What is the loss to the enterprise when the equipment fails 5 Is the performance of the new equipment what the current equipment is lacking? And it is important 6\\\\\\Other reasons your company thinks are necessary. There is no need to chase after the update of DCS. We have been using it for 10 years, and it seems that there are plans for another 10 years!
The two people above made a good point. The DCS contract stipulates that spare parts must be guaranteed for 10 years. If the capacity is not expanded, the hardware will basically not need to be upgraded. The upgrade of the software version should be stipulated in the contract, mainly free of charge. The manufacturer recommends that you upgrade, just to make money from you again. For example, many companies using Yokogawa are still using CS1000. Yokogawa has always recommended that they use CS3000, but there are no problems with their systems. Why upgrade? As long as spare parts are guaranteed, there is no need to worry.
What the people above said make sense. The DCS in the unit is HS2000-1.5. It is difficult to guarantee the hardware now. :'(
A set of DCS can be used in industry for 10 years or more. The reason why DCS is used well is that its hardware and software are quite reliable. As a control system, DCS requires professionals to perform daily maintenance, inspection, and repairs on it. A 4-year-old DCS should not be phased out or upgraded unless there are major hidden dangers in the system itself or your company has no place to invest.
As everyone above said, the key point is the supply of hardware spare parts. If there are still hardware spare parts available, there is really no need to upgrade unless it is for energy saving considerations and new equipment needs to be added, and the new equipment cannot be used in the original system.
Is it because DCS is unwilling to keep the old production line and continue to produce old hardware accessories? Let everyone upgrade to the latest version, and upgrade the hardware by the way. This is the best for them. Is this possible?
