How are GE’s control systems? Let’s all talk about it
Are they GE’s RX3I and RX7I PLCs? It’s a good product, but it’s a bit obscure; there are very few people who would ask questions about it. It’s best to choose Siemens for PLCs, as their after-sales service is the best among all these PLC manufacturers.
GE’s PLCs – I’ve worked with GMR models; they are basically no longer produced abroad, but companies in Beijing in China still manufacture them. They feature pure physical redundancy and can have multiple redundant units; they are used in large GE gas turbine systems. They come with a MARK VIE system, and the hardware also has full physical redundancy. It’s possible to configure custom overspeed protection cards, and these products have SIL certification. They are not very widely used in China.
I’ve sent the materials. Take a look for yourself. There is almost no after-sales support, but the stability thanks to triple redundancy is quite good.
The DCS should refer to the unit system and the SIS MARK VIE system
What about the MARK VIE system? They are promoting this system now, and we want to switch to it
Is it used on the unit? I think the system is okay; who will handle the engineering work? What unit configuration?
There is no after-sales support, and that’s a big problem. The hardware is fine, but what about the software?
No, in the past we wanted to replace the old systems with air compressors and oxygen compressors
The hardware is fine; multiple levels of redundancy are possible, with physical redundancy being the most secure option. The key aspect of the unit system lies in the software – its speed control response time is generally within the range of 20-40 ms, and the anti-stall algorithms are also satisfactory. What’s important is who will be responsible for implementing these features; if old units are replaced, will the new units retain the same performance curves? It needs to be optimized, right? The key lies with the person or team who develops this software; the algorithms themselves are more or less similar. It’s the way they are applied that matters truly. The reason CCC is so excellent is due to its algorithms. I’m getting a bit off-topic here, but in my opinion there’s no problem with using it; what’s important is whether it can be used effectively. You also want to save energy and reduce costs, after all, efficiency is what counts most.
