Separate fieldbuses avoid EMI and other problems
Thomas Kramer, Technical spokesman at the SafetyBUS p Club, discusses the arguments in favour of separate fieldbuses for safety and standard data.
SafetyBUS p applications grow from wood processing
Otto Baier, head of maintenance at Wiesner Hager in Altheim, Austria, describes how his company's SafetyBUS p implementation has developed since it was first installed in April 1999.
The requirements for developing this device have been established by the project group 'optical data transmission' within the Japanese branch of the SafetyBUS p Club International.
Typical fields of use are in applications where it is necessary to build up a flexible or moveable SafetyBUS p network.
Examples are the safe control of cranes for automated storage systems, the use of portal or indoor cranes, or track types for automated guided vehicles (AGV).
With a maximum optical transmission distance of 70 metres, wider distances between transmitter and receiver can be reached.
A scattering angle tolerance of 2 degrees for a maximum distance of 50m and 1 degree for distances over 50m permits manual adjustment of the devices.
An directly integrated LED diode scale visualises the intensity of the optical component.
Thanks to the ability to transmit data on different channels, it is possible to operate more than just one pair of devices simultaneously in one plant.
In order to keep the availability of a plant high, the optical data communication requires a particularly high insensitivity to interferences (light, reflections, dust, and vibrations, for example).
The equipment is protected to IP40 and is suitable for the use in industrial environments.
