ABB PM857K01 3BSE088385R1 / ABB PM858K01 3BSE082895R1 are AC 800M controller kits that execute control applications, coordinate ModuleBus I/O and connect controller communications through the TP830 processor base. PM857K01 is assigned to high-integrity projects, while PM858K01 is the standard controller kit for non-safety control.
The project role separates ABB PM857K01 3BSE088385R1 / ABB PM858K01 3BSE082895R1 before memory or package details are compared. PM857K01 uses the safety-capable controller and Control Builder Safe environment; PM858K01 uses the standard controller path and must not be promoted into a safety role because the enclosures and common accessories appear similar.
Each ABB PM857K01 3BSE088385R1 / ABB PM858K01 3BSE082895R1 kit includes the processor, TP830 baseplate, CEX/ModuleBus terminators and battery items defined for that order record. Installation therefore checks the complete kit article, software generation and controller project before any existing CPU is replaced.

The CPU scans the loaded application, updates its task data and exchanges process values with connected S800 I/O. Task timing and controller load are checked with the real communication paths active, not from memory capacity alone.
CN1/CN2 carry the configured control-network connections, COM3 serves the serial channel and COM4 provides the documented service-tool path. Keeping these ports in their assigned roles lets engineering access remain separate from process-network traffic.
When redundancy is configured, the primary and backup controllers exchange state through the documented redundancy arrangement. Commissioning verifies matching project versions, synchronized retain data and a controlled role change before the pair is released.
PM857K01 belongs to the high-integrity execution path and is commissioned with the specified safety engineering environment, safety application and required supporting hardware. The safety project, not the front-panel appearance, establishes which functions may be credited.
PM858K01 performs standard process control and remains outside the certified safety role assigned to PM857K01. Standard and safety code are therefore reviewed against the installed article before a project is restored.
Replacement work records the article number, firmware, project version, retain-data backup and controller role before power is removed. Outputs return to service only after hardware identity, application state and the required engineering checks agree.
Moore Automation covers ABB, Honeywell, Siemens, Rockwell Automation, Schneider Electric, Emerson and other industrial automation manufacturers.
The scope includes controllers, distributed I/O, communication interfaces, drives and monitoring hardware while each enquiry remains tied to its exact model record.
