Because ProfiBus uses a cyclic periodic polling mechanism between masters and slaves, it is also deterministic. Module Data Technical data and descriptions of the functions of signal modules, power supply modules and interface modules. Please contact your reeds training center, or the central training center http: O escravo AS-i, como visto na Figura 7.

You can find the documentation free of charge on the Internet http: The accompanying documentation describes the standard functionality of the IM module. Flag Data exchange blocked: Read Extended ID Code 2: ProfiBus DP most often uses a single class 1 master device mono-mastercyclically polling many distributed slaves. Master-to-master communication is normally not permitted in Profibus, except in order to grant bus access rights to another master via the exchange of a token.

It is important to note that all ProfiBus slaves have the same priority, and all network communication originates from the master. A class 2 master is a special device primarily used for commissioning slaves and for diagnostic purposes. The example used in this Getting Started guides you through the various steps in commissioning required to obtain a fully functional application. Siemens e Festo desenvolveram em conjunto o chip SAP4.

That is, the behavior of a ProfiBus system can be reliably predicted over time. A master uses this information to set up communication with each slave during startup. As part of cyclic DP communication, the actual drive values encoder values are transferred from the IM module to the controller via the isochronous PROFIBUS, and the speed setpoints calculated by the controller are transferred to the IM module. A master will send parameterization and configuration telegrams to all of its assigned slaves a slave may only be write-accessed by its assigned master, the master that parameterized and configured it during startup.

Table of contents 4.

In attempting to establish communication, ds master starts with the lowest address slave and ends with the highest address slave. Note that the exchange of bus access rights via this “token ring” only applies between masters on the bus. Como indicado pela Figura 7. This is a brief overview of Profibus-DP.

ProfiBus was created in by the German government in cooperation with several manufacturers of At the end of this data cycle, additional time gap time is allotted to provide for acyclic communication between a class 2 master and the same slaves.

However, ProfiBus also allows for acyclic communication between class 2 masters and slaves, making more than one active station or master possible. Apesar de tecnicamente, o “AS-i” ser um barramento, o termo interface mostra que ele fornece uma interface simples para acesso a sensores e atuadores apostilz campo.

Low-voltage switchgear and orofibus — Part 1: However, master-to-master communication between two mono-master systems can ce facilitated using a DP-DP gateway. Arquitetura de um escravo AS-i Fonte: A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage. Profibus ProfiBus was created in by the German government in cooperation with several prlfibus of The GSD files of each device connected via the network slaves and class 1 masters only are compiled into a master parameter record which contains parameterization and configuration data, an address allocation list, and the bus parameters for all connected stations.

The class 2 master which currently holds the token has the opportunity to exchange data with all the slaves within a specific period of time called the token half-time or token hold-time TH.

All data communication exchanges between a master and slave originate from the master device. A rede AS-i suporta qualquer topologia de cabeamento: In fact, ProfiBus was designed to guarantee a deterministic response.

These notices shown below are graded according to the degree of danger.

Possui sempre valor “0”. For the integration of an S with an IM in a system or unit, dw are important rules that you must observe.

After a master receives its master parameter record, it is ready to begin exchanging data with its slaves. Parte 1 de 3.
