ComBricks PROFIBUS Fiber Optic Module

ComBricks PROFIBUS Fiber Optic Module

This multifunctional module designed for PROFIBUS communication over multimode optical fibers. It enables galvanic isolation of segments and extends the communication distance up to 3 km, which is especially beneficial in industrial environments with higher levels of interference or a larger number of devices. The module supports all topologies except ring topology.

Key Advantages

• Signal transmission up to 3 km
• Compatible with Siemens optical modules and other major brands.
• Resistance to strong EMC interference
• Point-to-point, bus, star or hub topologies
• Online diagnostics and management via web interface without the need for additional software
• Fault indication by LEDs and e-mail notifications
• Galvanic isolation of segments
• Option to connect optical and copper segments (in combination with other ComBricks modules)

How the ComBricks PROFIBUS Fiber Optic Module Works

The ComBricks fiber optic module enables PROFIBUS signal transmission between ComBricks modules or between ComBricks and other PROFIBUS fiber optic modules from other manufacturers. Optimal solution for creating a PROFIBUS galvanically isolated connection over long distances (up to 3 km), with the possibility of creating a point-to-point, bus, star and hub topology. Supports redundant module connections. Optical cables are connected to the module via 4 metallic ST/BFOC connectors – 2 for each channel.

Reliably communicates with or replaces SIEMENS OLM modules and modules from other well-known manufacturers. Can be combined seamlessly with all ComBricks optical and other modules in one assembly. It is therefore suitable for easy interconnection of metallic and optical cables, for example in locations with strong EMC interference.

Possible network topology designs:

ComBricks Module Configuration

Module settings are performed using DIP switches on the bottom of the module. The advantage is that the ComBricks module settings are immediately visible at first glance. The second configuration option is via the ComBricks web interface.

Network Diagnostics Options

These optical modules also provide excellent diagnostic capabilities. The operator standing directly at the device can use the LED indication.

Settings via the web interface of the control station:

 
Module status on the web interface of the control station, unlike the ComBricks XM/SM/MM versions, this module does not have optical signal quality monitoring or alarm options based on optical signal status.
