01
Overview
The controller core within an AC 800M configuration.
PM858K01 is an AC 800M processor unit for non-redundant controller configurations. The CPU executes the configured control applications and communicates with I/O and network components through the AC 800M architecture.
The processor unit is supplied with the TP830 baseplate and associated termination hardware specified for the PM858K01 package.
Identification first: order against the complete ABB article number 3BSE082895R1, not only the PM858K01 family name.

Application & Fault
What usually drives a maintenance search for the exact part number.
Search trigger Controller fault Maintenance teams may search PM858K01 when the installed processor unit is suspected rather than an individual I/O module.
System impact Control execution affected A processor-unit failure can interrupt application execution and controller-dependent functions.
Before removal Capture configuration Record the article number, controller architecture and system version before replacement work begins.
For documentation searches, use the complete term PM858K01 manual or the ABB article number 3BSE082895R1 to avoid mixing information from nearby AC 800M variants.

FAQ
Five questions focused on actual replacement and purchasing decisions.
Is PM858K01 a redundant AC 800M processor?
No. PM858K01 is specified as a non-redundant processor-unit configuration. A redundant architecture should be checked separately before selecting another processor package.
What is the ABB article number for PM858K01?
The article number identified for PM858K01 is 3BSE082895R1. Use the complete article number when requesting a quotation or checking an installed unit.
Does PM858K01 use a TP830 baseplate?
Yes. The PM858K01 package documentation identifies the TP830 baseplate together with the specified CEX-Bus, ModuleBus and RCU-Link termination hardware.
Which software versions should be checked before replacement?
ABB documentation identifies compatibility with System 800xA 6.0.2 and Compact Control Builder 6.0.0-1 and later. The installed system version should still be confirmed before replacement.
What information should I send when ordering PM858K01?
Send the complete Part Number, Quantity, Destination, Required Date, Machine and System information. For installed-system replacement, including the current configuration/version helps avoid selecting an incompatible package.
