Siemens offers PROFIBUS link devices for different tasks:

  • Communication between two PROFIBUS DP masters
  • Connecting RS232C devices to PROFIBUS DP
  • Connecting PROFIBUS devices through a wireless network

DP/DP Coupler

Two PROFIBUS DP masters cannot exchange data between each other. They need a DP slave device in between, which belongs to both DP masters.

  • Connect two independent PROFIBUS DP networks together
  • Both PROFIBUS networks can have different parameter e.g. different transmission speed
  • Represents an independent DP slave to each PROFIBUS DP master
  • 0-244 Byte input and 0-244 Byte output user data can be exchanged
  • Transmission speed up to 12 Mbaud

DP/RS232C Link

Devices with an RS232C interface can be directly connected to PROFIBUS DP using the RS232C link. The link is used as a gateway and operates as a PROFIBUS DP slave.

  • Converter between an RS232C (V.24) interface and PROFIBUS DP
  • The link supports the procedures:
    • The 3964R procedure
    • A free ASCII protocol with control over Character delay time, Start / End delimiter or constant data length
  • 0-224 Byte input and 0-224 Byte output user data can be exchanged
  • Transmission speed up to 12 Mbaud

Infrared Link Module

The ILM permits wireless – infrared – PROFIBUS data transmission to DP slave devices within a range of 15 meters.

  • Wireless data transmission over short distances – up to 15 meter
  • Illuminates a circle of 4 meter in diameter in 11 meter distance
  • Transmission speed up to 1.5 Mbau
Infrared Link Module
    Communication Capabilites with an ILM:

  • Connectivity: one-to-one or one-to-two between ILMs
  • Communication with mobile devices / vehicles possible
  • Communication with changing stations e.g. along a conveyor line
  • ILM can replace worn systems such as slip rings
