Abstract
The present invention describes a method for configuring a station connected to a field bus, wherein a logical address is allocated to said station. The method comprises the steps of: transmitting said logical address from an address-allocation unit to said station; transmitting a physical address from said address-allocation unit to said station, said physical address corresponding to an assumed physical position of said station relative to said field bus; verifying said physical address being transmitted to said station based on an actual physical position of said station relative to said field bus; and storing said transmitted logical address in a memory of said station depending on the verification of said physical address.

In a system comprising a field bus and a station connected to said field bus, said field bus providing a circulating telegram traffic complying with existing Interbus specifications, a method of allocating a logical address to said station, said method comprising the steps of
- transmitting said logical address from an address-allocation unit to said station;
- transmitting a physical address from said address-allocation unit to said station, said physical address corresponding to an assumed physical position of said station relative to said field bus;
- determining an actual physical position of said station relative to said field bus by evaluating said circulating telegram traffic;
- comparing said transmitted physical address and said actual physical position determined;
- and
- storing said logical address in a memory of said station if said physical address and said actual physical position match with each other.
A method of allocating a logical address to a station connected to field bus, said station having a position-determining unit, and said method comprising the steps of
- transmitting said logical address from an address-allocation unit to said station;
- transmitting a physical address from said address-allocation unit to said station, said physical address corresponding to an assumed physical position of said station relative to said field bus;
- determining an actual physical position of said station relative to said field bus by means of said position-determining unit;
- verifying said transmitted physical address based on said actual physical position determined;
- and
- storing said logical address in a memory of said station if said physical address and said actual physical position match with each other.
A method of configuring a station connected to a field bus, wherein a logical address is allocated to said station, said method comprising the steps of
- transmitting said logical address from an address-allocation unit to said station;
- transmitting a physical address from said address-allocation unit to said station, said physical address corresponding to an assumed physical position of said station relative to said field bus;
- verifying said physical address being transmitted to said station based on an actual physical position of said station relative to said field bus;
- and
- storing said transmitted logical address in a memory of said station depending on said step of verification of said physical address.
A Station for connecting to a field bus, said station comprising a receiver for receiving a logical address which is to be allocated to said station, and for receiving a physical address which corresponds to an assumed physical position of said station relative to said field bus, said station further comprising a position-determining unit for determining an actual physical position of said station relative to said field bus, a memory for storing said logical address, and a comparator unit for comparing said physical address transmitted and said actual physical position determined, wherein said comparator unit acts upon said memory in dependence of a match found between said physical address transmitted and said actual physical position determined.
