Fieldbus Connectivity

Fieldbus Connectivity (DeviceNet, Profibus-DP, CANopen, Interbus)

Early interconnection schemes employed point-to-point wiring where individual wires connected input and output devices to host controllers. On large automation jobs, this could account for tens and even hundreds of thousands of points of termination. To cut down on wiring cost and installation time, multi-conductor cables became popular. The next innovation was the advent of the bus system. Rather than communication between device and host controller using a bulky home run cable, bus systems collect signals from multiple devices and transmit them on a single cable. Many digital networks are in use today for industrial automation applications. These networks range from low-level systems that gather data from simple discrete devices to sophisticated networks in which intelligent devices implement distributed control.

The LioN-Link Decentralized I/O Fieldbus System
The LioN-Link decentralized I/O fieldbus system can create line topologies up to 100 meters in length. The system consists of bus coupler modules, which function as the interface to higher-level fieldbus systems such as ProfibusCANopenDeviceNet or ProfiNet, and protocol independent I/O modules.

Engineers only need to make minimal changes to the hardware if their end customers use different transmission protocols for the connection of systems to their communications network. Only the BusHead requires an address setting, the fieldbus independent I/O modules do not require commissioning. Module addressing and terminating resistors are not required in either link line. Both features contribute to protection against manipulation.

Decentralized I/O Blocks/Modules

  • LioN-M I/O Modules: Can handle up to 16 inputs/16 outputs where channels can be used universally as inputs or outputs. Blocks are available in DeviceNet and Profibus-DP
  • LioN-S I/O Modules: Can handle up to 8 inputs/8 outputs where channels can be used universally as inputs or outputs. Blocks are available in DeviceNet and Profibus-DP
  • LioN-Link IP67 Distribution System: an IP67 rated On-Machine I/O solution. Consists of bus coupler modules which provide the connection between the entire fieldbus system and the fieldbus independent I/O modules.
