Siemens 6GK1502-2CB10 SIMATIC NET OLM G11 Optical Link Module
The Siemens 6GK1502-2CB10 serves as the primary 6GK1502-2CB10 Optical Link Module utilized to execute bi-directional signal conversion between RS-485 electrical bus lines and glass fiber optic links across SIMATIC NET PROFIBUS DP and PA platforms. Furthermore, the unit routes data over point-to-point and line topologies while providing galvanic isolation. Consequently, this hardware component eliminates ground potential differences and prevents electromagnetic noise interference across extended fieldbus distances.

Deterministic PROFIBUS Transmission and Firmware Compatibility
Siemens OLM/G11 modules maintain deterministic communication timing across PROFIBUS DP and PA network segments. By processing optical conversion at the physical layer without introducing variable frame delays, the hardware preserves strict master-slave cycle synchronization. In addition, firmware flash compatibility ensures seamless interaction with PROFIBUS bus masters and legacy network nodes, enabling transparent signal pass-through across line configurations without requiring system re-configuration.
Frequently Asked Questions
Q: How does the integrated analog test port facilitate optical link measurement?
A: The test port provides a DC voltage output proportional to the received optical power level, allowing technicians to measure fiber attenuation using a standard multimeter without interrupting active bus traffic.
Q: What is the migration path when replacing the discontinued 6GK1502-2CB10 module?
A: The official successor model is the 6GK1503-2CB00 (OLM/G11-1300 V4.0). Its mechanical enclosure and electrical pin assignments align with the standard SIMATIC NET footprint to enable direct physical replacement in existing cabinet layouts.
Q: Does the module require manual switch setting for PROFIBUS baud rate selection?
A: No, the onboard transceiver features automatic baud rate detection across all standard PROFIBUS transmission speeds from 9.6 kbit/s to 12 Mbit/s.
Field Installation Guidelines
Snap the module vertically onto a standard 35 mm DIN rail inside the enclosure. Maintain a minimum vertical clearance of 50 mm above and below the housing ventilation slots to ensure unimpeded convective cooling across the -40 deg C to +70 deg C operating temperature range.
Clean all BFOC optical connectors with lint-free wipes before inserting them into the glass fiber ports to prevent signal attenuation. Connect the shield of the RS-485 copper cable to functional earth ground via a low-impedance connection, and route communication cabling through dedicated wiring channels away from high-voltage AC power lines.
