HOLLYSYS HOLLIAS MACS-K CONTROLLER

K-CU11

HOLLiAS MACS-K main controller supporting redundant control, network resilience and large I/O capacity.

Product Profile

K-CU11 is a Hollysys main controller for the HOLLiAS MACS-K distributed control system. It is designed for field control stations within the MACS system architecture, coordinating control logic, I/O data and communication across the controller domain.

Hollysys documents redundant controller configuration together with redundancy for both the CNET control network and SNET system network.

System Role

Within the HOLLiAS architecture, management, system and control networks are separated into MNET, SNET and CNET layers. K-CU11 operates in the field control station layer and coordinates connected I/O modules through the system's controller and I/O-bus architecture.

The controller is based on the K-CU01 generation and adds an SM3 encryption processor plus expanded storage used for trusted boot and dynamic trust measurement. Hollysys states compliance with the IEC 62443-3 framework.

Compatibility

Use only with the HOLLiAS MACS-K hardware, backplane, network and software release approved for K-CU11. Confirm controller redundancy pairing, firmware, project database, I/O count and network configuration before replacement.

Capacity values are controller limits from the Hollysys system specification; actual usable capacity depends on application load, control-cycle design and installed system configuration.

Applications

Large or medium process-control stations requiring redundant control and networks, up to 100 I/O modules, extensive point handling and PID control.

Suitable project contexts include energy, chemicals, process manufacturing and other DCS applications implemented on the supported HOLLiAS MACS-K platform.
