Siemens 6GK1503-3CA00 PROFIBUS OLM/P12 V4.0 optical link module

The captured Siemens data sheet identifies 6GK1503-3CA00 as a PROFIBUS OLM/P12 V4.0 optical link module. The data sheet specifies one RS485 interface, two plastic FOC interfaces, a 24 V DC supply, and 9.6 kbit/s to 12 Mbit/s PROFIBUS transfer rates.

System function and position

Rebuilt from individual evidence

The captured Siemens data sheet identifies 6GK1503-3CA00 as a PROFIBUS OLM/P12 V4.0 optical link module.

The data sheet specifies one RS485 interface, two plastic FOC interfaces, a 24 V DC supply, and 9.6 kbit/s to 12 Mbit/s PROFIBUS transfer rates.

Unknown: fiber installation loss, topology limits, installed configuration, and current commercial availability require separate evidence.

The module bridges electrical PROFIBUS traffic to plastic-fiber optical links in the controller network.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Converts PROFIBUS traffic between the RS485 interface and plastic-fiber optical links.
System position: Sits between an electrical PROFIBUS segment and the optical network path in the automation system.
Upstream / inputs: Receives network traffic through the RS485 interface and 24 V DC powered module.
Downstream / outputs: Transmits converted PROFIBUS traffic through the two plastic FOC interfaces.
Limitations: Unknown: fiber installation loss, topology limits, installed configuration, and current commercial availability require separate evidence.
