Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density

The bus switching module connects Genius I/O blocks to two serial communication busses simultaneously, maintaining redundant signal pathways across token-passing network loops. By monitoring the integrity of active transmission channels, the module dynamically transfers communication loops in the event of a bus fault, protecting real-time control sequences. I/O density scaling and predictable physical switching characteristics ensure minimal latency during bus transitions, preserving backplane communication velocity and deterministic update rates across decentralized automation architectures.

Frequently Asked Questions

Q: What power supply voltage is required to operate the IC660BSM021 switching module?

A: The IC660BSM021 is designed for low-voltage DC applications and operates on a nominal 24 VDC or 48 VDC supply rating.

Q: How many serial bus lines can be interfaced through a single IC660BSM021 module?

A: The module contains dual serial bus ports designed to connect Genius I/O modules to 2 redundant serial busses concurrently.

Field Installation Guidelines

• Mount the module chassis securely onto a grounded mounting surface or DIN rail layout according to standard Genius hardware practices.
• Connect primary and secondary Genius Bus twisted-pair cables to their respective bus terminal sets, ensuring shield continuity is maintained along both network paths.
• Verify that 24/48 VDC power wiring polarity and voltage limits match specifications prior to energizing the module.
