Core Functions

• ControlNet Communication: Acts as scanner/adapter for high‑speed, deterministic I/O and messaging.

• Network Redundancy: Dual BNC ports support redundant ControlNet cabling.

• AutoMax Integration: Connects AutoMax PLCs to FlexPak 3000 drives, I/O, and HMIs.

• Configuration & Diagnostics: RS‑232 port for setup, monitoring, and fault logging; 7‑segment LED for error codes.

• Data Exchange: Real‑time exchange of drive status, setpoints, and I/O data.

• System Protection: Supports network fault detection and isolation.

Application Scenarios

• AutoMax‑based systems requiring ControlNet connectivity (metallurgy, mining, paper, steel).

• FlexPak 3000 DC drive integration for coordinated motion and process control.

• High‑speed motion control (conveyors, winders, extruders).

• Distributed control systems (DCS) with multi‑device coordination.

• Legacy system upgrades migrating from older protocols to ControlNet.

Difference from 0-58820

• 0-58820-1 = Revision 1 of the MBCN module; 0-58820 is the base revision.

• Fully pin‑compatible; 0-58820-1 replaces 0-58820 directly.

• Component and firmware updates for improved reliability and compatibility.
