Industrial Control Network Integration

The PM866K02 uses ABB controller architecture for redundant processing tasks within System 800xA environments. Therefore, the kit integrates dual PM866K01 processor units with dedicated communication accessories to support synchronized controller operation.

The processor arrangement supports backplane bus communication and controller redundancy functions. Additionally, the included TK850 CEX-Bus expansion cable provides processor-to-expansion connectivity, while the TK851 RCU-Link cable supports redundant controller communication paths.

ABB processor platforms apply deterministic control communication methods for I/O density scaling and firmware flash compatibility management. These functions allow engineering teams to maintain consistent controller configuration across redundant processing assemblies.
