Embodiment Construction

[0019] Thus, the present invention provides the development of a Profinet IO-compatible user equipment with a selector switch in order to obtain the station identifier directly from the corresponding setting of the selector switch in conjunction with a strictly defined group identifier, wherein said A group identifier is specific to a corresponding particular group of user equipment.

[0020] The station identifier compatible with Profinet IO is specified by setting the selector switch, whereby all the problems of the prior art as described above can be solved, the selector switch is installed directly on the device, whereby the network user equipment identification The identifier is generated in combination with an identifier element that is strictly specified for each Profinet IO-compatible device and is specified for the specific group of devices that contains the device and by corresponding setting of the switches.

[0021] Furthermore, for the automatic assignment of the ...

Abstract

The invention relates to a method and an apparatus for allocating subscriber device addresses in a Profinet IO network. It is an object of the invention to demonstrate a novel, further way of ensuring the allocation of station identifiers, which are needed in Profinet IO systems and on the basis of which the subsequent automatic subscriber addressing is performed by ascertaining and associating logical and physical addresses, in a simple and error-resistant manner. The invention thus provides for the development of a Profinet IO compatible subscriber device having a selector switch such that the station identifier is obtained directly from the respective setting of the selector switch in combination with a firmly prescribed group identifier which is specific to a respective particular group of subscriber devices.

Description

technical field [0001] The invention relates to a method and equipment for allocating user equipment addresses in a Profinet IO network. Background technique [0002] As we all know, Profinet IO is an automation standard proposed by the Profibus User Organization (PNO) and based on Ethernet. The Profinet IO is basically 100% based on the Ethernet standard (according to IEEE802.3) and operates in full-duplex mode , In addition, it also supports switching Ethernet with a transfer rate of 100Mb / s. This means that not only process and production data can be captured at field level, but also that this data can be seamlessly fed into multi-regional data capture systems, thus vertically integrating local peripherals. [0003] Compared with Profibus, which operates according to the "master-slave model", Profinet IO actually operates based on a producer-consumer model. Doing so saves call telegrams, especially since it also means that one telegram can be used simultaneously with th...
