Comparison item PM510V08 (old model AC410) HC800/CP800 (new model S+)
Platform Advant OCS/AC410 (Bailey old series) Symphony Plus (new DCS platform)
Processor 25MHz 68020 256MHz ColdFire
Memory 8MB (maximum 16MB) 64MB (HC800)
I/O capacity ≤ 1000 points, 5000+points (HC800)
Network Modbus/DeviceNet PN800 Ethernet, RFO810 fiber optic
The current situation is that production is suspended/the main force in the spare parts market is in production, and new systems are preferred
5、 Typical application scenarios
Electricity: DCS retrofit and spare parts replacement for old thermal/hydroelectric units
Chemical industry: Maintenance and expansion of old AC410 systems in large-scale facilities
Metallurgy: existing Bailey systems such as rolling lines and heating furnaces
Water treatment: Upgrading of old DCS and spare parts for large water plants
