FAQs
Q1: What is the primary function of the PM867K02?
It is a redundant High Integrity processor unit kit for the AC 800M controller platform. It executes safety-critical and business-critical control logic in System 800xA, with dual CPUs operating in hot-standby configuration to ensure uninterrupted operation in critical processes such as refineries, LNG terminals, and power plants.
Q2: What is included in the PM867K02 kit?
The kit includes 2 x PM867 CPU units, 2 x TP830 baseplates, 2 x TB807 ModuleBus terminators, 1 x TK850 CEX-Bus expansion cable, 1 x TK851 RCU-Link cable, and 2 x memory backup batteries (4943013-6).
Q3: How does the redundancy work?
Two PM867 CPUs operate in hot-standby (1:1) configuration, synchronized via the TK851 RCU-Link cable. The primary CPU processes all tasks while the backup mirrors data in real time. If the primary fails, the standby takes over in ≤10 ms without interrupting field I/O or HMI communication.
Q4: What is required for SIL 3 certification?
SIL 3 functionality is enabled by adding the SM812 safety module and using SIL-certified software. The controller is TÜV certified for SIL 2 and SIL 3 (IEC 61508), allowing safety and standard control in one unit.
Q5: What are the typical applications for this controller?
It is used in oil & gas (ESD, F&G, PSD systems), power generation (turbine control, reactor cooling), chemical/petrochemical (SIL3 safety loops), LNG terminals, and rail transit signal interlocking systems where uninterrupted operation is essential.
