Product Description for Siemens 6GK1503\u20113CB00 PROFIBUS Optical Link Module<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
6GK1503\u20113CB00 is a new\u2011original Siemens Optical Link Module (OLM) for PROFIBUS\u2011DP field\u2011bus networks. It converts electrical RS\u2011485 PROFIBUS\u2011DP signals into optical signals and vice versa. This device serves as a signal converter between copper\u2011cable\u2011based PROFIBUS segments and fiber\u2011optic cables. It eliminates ground\u2011loop interference and extends communication distances compared with conventional copper PROFIBUS\u2011DP wires. This OLM supports multimode optical fiber and works with S7\u2011300, S7\u2011400, S7\u20111500 PLC, ET200\u2011series distributed I\/O modules and PROFIBUS\u2011DP\u2011compliant field\u2011devices. It builds reliable PROFIBUS\u2011DP communication for high\u2011noise industrial environments such as metallurgical workshops, power plants and heavy\u2011machinery factories where electromagnetic interference is serious. It is mounted on standard DIN rails inside control cabinets and complies with SIMATIC network configuration rules.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Signal Conversion\n
    <\/div>\n

    Transform RS\u2011485 electrical signals from PROFIBUS\u2011DP copper cables into optical signals for fiber\u2011optic transmission and convert optical signals back into RS\u2011485 signals on the receiving side. It fully complies with PROFIBUS\u2011DP protocol without changing original bus data content.<\/li>\n

  2. Long\u2011Distance Transmission\n
    <\/div>\n

    It extends PROFIBUS\u2011DP communication range. For multimode fiber, the maximum transmission distance can reach 3000\u202fmeters, far longer than 1000\u2011meter limit of copper\u2011based PROFIBUS\u2011DP cable at 12\u202fMbit\/s baud\u2011rate.<\/li>\n

  3. Isolate Electromagnetic Interference\n
    <\/div>\n

    Optical fiber transmission achieves complete galvanic isolation between different PROFIBUS\u2011DP segments, effectively avoiding ground\u2011loop currents and interference from servo\u2011drives, frequency converters and high\u2011power motors.<\/li>\n

  4. Network Topology Selection\n
    <\/div>\n

    Support point\u2011to\u2011point and linear topologies. Multiple OLM units can be cascaded to construct large\u2011scale PROFIBUS\u2011DP optical\u2011fiber networks. Built\u2011in 120\u2011ohm terminating resistor can be activated for bus endpoints.<\/li>\n

  5. Status Diagnosis\n
    <\/div>\n

    LED indicators display power status, optical link state and PROFIBUS\u2011DP bus faults. Fault information can be captured via STEP\u20117 or TIA Portal for troubleshooting.<\/li>\n

  6. Data\u2011rate Adaptation\n
    <\/div>\n

    Automatically adapts to PROFIBUS\u2011DP baud\u2011rates ranging from 9.6\u202fkbit\/s up to 12\u202fMbit\/s without manual parameter setting.<\/li>\n

  7. Expansion of Bus Stations\n
    <\/div>\n

    Each electrical port can connect multiple PROFIBUS\u2011DP nodes, helping users expand total quantity of DP\u2011slave devices across different workshop areas.<\/li>\n<\/ol>\n<\/div>\n
