RS-485 to plastic-fiber conversion for documented PROFIBUS optical networks and redundant ring topologies.
Siemens identifies the complete order number 6GK1503-3CA00 as the PROFIBUS OLM/P12 V4.0 optical link module. It connects one electrical RS-485 PROFIBUS interface to two plastic-fiber optical interfaces implemented through four BFOC sockets.
The unit includes a signaling contact and measuring output and supports ring redundancy. It is intended for documented PROFIBUS optical network structures where exact interface type, fiber medium, connector format, power supply and topology must be matched before replacement.

| Application | Engineering Relevance |
|---|---|
| PROFIBUS optical backbone | Converts the electrical RS-485 segment to two plastic-fiber optical channels for distributed network construction. |
| Redundant optical ring | Supports ring redundancy for higher network availability in documented PROFIBUS topologies. |
| Electrical isolation between plant areas | Uses fiber transmission to bridge electrically noisy or separated installation zones. |
| Legacy OLM/P12 maintenance | Provides an exact V4.0 reference for like-for-like spare-part planning and controlled migration. |
Siemens lists the exact 6GK1503-3CA00 as PM410: Product cancellation and states that the product is cancelled since 01.10.2016. The official successor is 6GK1503-3CA01, identified as PROFIBUS OLM/P12 V4.1. A migration decision should verify optical power budget, interfaces, topology and cabinet wiring.
It is the PROFIBUS OLM/P12 V4.0 optical link module with one RS-485 and two plastic-fiber interfaces.
The module has two optical interfaces implemented through four BFOC sockets.
Siemens specifies 9.6 kbit/s to 12 Mbit/s, plus 45.45 kbit/s for PROFIBUS PA.
Yes. Siemens lists ring redundancy as a product function.
Siemens lists PM410: Product cancellation, with cancellation effective from 01.10.2016.
Siemens identifies 6GK1503-3CA01, the PROFIBUS OLM/P12 V4.1, as the successor.
