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
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
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: o The 3964R procedure o 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
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
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
