More Information

Overview Manuals Copper Link Optical Paths Diagnostics Mounting

Features:

  • One RS485 channel connects the electrical PROFIBUS segment.
  • Two optical channels support POF and PCF fiber through four BFOC sockets.
  • A signaling contact and measuring output support link supervision.
Siemens 6GK1503-3CA00 transfers PROFIBUS telegrams between copper and fiber segments.

The two optical channels keep transmit and receive paths organized through separate BFOC connections.

Selectable data rates let the module follow the transmission setting used by the connected PROFIBUS network.

The Siemens 6GK1503-3CA00 PROFIBUS OLM/P12 V4.0 Optical Link Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Electrical PROFIBUS Connection

  • Bus entry: The RS485 interface receives the electrical PROFIBUS segment.
  • Telegram path: PROFIBUS traffic passes between the RS485 channel and both optical channels.
  • Data rate: The configured transmission rate must match the connected PROFIBUS network.
  • Segment boundary: The copper connection remains electrically separate from the fiber transmission paths.

POF and PCF Channel Structure

  • Channel count: Two optical channels provide separate fiber branches.
  • Socket pairing: Four BFOC sockets divide transmit and receive connections across the two channels.
  • POF limit: Plastic optical fiber uses the documented shorter segment distance.
  • PCF reach: Polymer-clad fiber extends the supported optical segment to the specified longer distance.

Link and Signal Supervision

  • Optical level: The measuring output supports checking the received optical signal condition.
  • External indication: The signaling contact can pass a module condition to an external circuit.
  • Channel isolation: Separate optical paths help identify which fiber branch requires inspection.
  • Rate check: A data-rate mismatch should be excluded when communication is not established.

Supply and Installation Limits

  • Power source: The module uses a 24 V DC supply within the documented permissible range.
  • Cabinet use: IP40 protection requires a location appropriate for the module enclosure.
  • Temperature limit: The installed module must remain within 0 to +60 °C during operation.
  • Fiber handling: POF or PCF cables must be routed without exceeding their connector and bend limitations.
Description
Siemens 6GK1503-3CA00 is a SIMATIC NET PROFIBUS OLM/P12 V4.0 optical link module that converts an electrical RS485 segment into two optical PROFIBUS channels. The module links copper bus devices with POF or PCF fiber sections without changing the PROFIBUS telegram structure.

At the electrical side, 6GK1503-3CA00 receives the PROFIBUS signal through its RS485 interface. Four BFOC sockets form the transmit and receive paths for two optical channels, so each fiber branch remains separately connected and supervised.

The selectable transmission rate of 6GK1503-3CA00 extends from 9.6 kbit/s to 12 Mbit/s, with 45.45 kbit/s available for PROFIBUS PA coupling. POF links are limited to the documented shorter distance, while PCF fiber supports the longer specified segment.

Powered from 24 V DC, 6GK1503-3CA00 also provides a signaling contact and measuring output for module and optical-level supervision. Its IP40 enclosure and 0 to +60 °C operating range require an appropriate protected mounting location.
