Configured for controller program execution and rack-based processing functions in ABB Stromberg automation systems, the ABB Stromberg CPU86-NDP (CPU86NDP CPU Processor Board) provides direct processing control within the installed rack architecture.

Model Identification

The ABB Stromberg CPU86-NDP is a rack mounted CPU Processor Board designed for controller-level processing tasks. The module is identified by the base model CPU86NDP and belongs to ABB Stromberg control hardware platforms. The manufacturer has discontinued this model.

Hardware Specifications

Controller Architecture Characteristics

The CPU86-NDP is designed for ABB Stromberg rack-based controller systems where processor execution, memory handling, and internal system communication are managed through the controller backplane structure.

ABB controller platforms require correct hardware revision matching and firmware flash compatibility checks when replacing processor boards. The CPU module configuration must correspond with the existing rack hardware to maintain correct system operation.

The Stromberg CPU architecture uses dedicated controller communication paths to coordinate processor operation with connected I/O modules. Backplane bus communication velocity and module addressing depend on the complete installed system configuration.
