System Architecture & Signal Flow
The PM862K02 mounts directly into the AC 800M controller backplane (TB820/TB840 series). The CPU communicates with I/O modules via the internal S800 I/O bus at high speed. Ethernet Port 1 connects to the plant control network (MMS/OPC-UA to System 800xA), while Ethernet Port 2 is reserved for engineering access or redundancy synchronization. The RS-232 service port provides local configuration and firmware update capability. In redundant configurations, two PM862K02 units operate in active/standby mode with automatic state synchronization.

Technical FAQ
Q: Is PM862K02 compatible with PM861K01/PM861K02?
A: Yes. The PM862K02 is a direct functional upgrade and is backward compatible with existing AC 800M backplanes and I/O configurations. No hardware modifications required.
Q: Can PM862K02 be used in a redundant pair with PM861?
A: No. Redundant pairs must use identical CPU models. Both units in a redundant configuration must be PM862K02.
Q: What software is required to program the PM862K02?
A: ABB Control Builder M (CBM) version 5.1 or later is required. The module supports IEC 61131-3 programming languages including FBD, LD, ST, IL, and SFC.
Q: Does Konmask provide warranty on this module?
A: Yes. Konmask provides a 90-day functional warranty on all tested units. Extended warranty options are available upon request.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For sourced units, lead time is typically 5–15 business days depending on availability.
