ABB CP800 Communication Control Processor

ABB CP800 (Symphony Plus HPC800 System Communication Processor)
CP800 is a dedicated communication control processor for ABB Symphony Plus (HPC800) DCS system. Its core is responsible for PN800 factory network communication, multi protocol gateway, and system data forwarding. It is a standard communication module for HPC800 controller and will still be available for sale in 2026.
