  • Page 6: Introduction

    1.1 Terminology Throughout this document the term "user" refers to the person or persons who are developing a fieldbus product based on the ANYBUS DATATRANSFER module. The end-user of the product is referred to as the "customer". As in all communication systems the terms "read" and "write" can be ambiguous, because their meaning depends on which end of the link is being referenced.

  • Page 7: Description Of The Anybus Datatransfer Module

    Since different hardware is required for the different interfaces, only one of the above mentioned access methods can be used in one module. Also note that there is one ANYBUS DATATRANSFER module for each fieldbus system. The synchronous interface is only available for development of customer specific products.

  • Page 8: Parallel Interface

    The serial interface is available as an asynchronous interface, RS232 with TTL level.. The asynchronous serial interface allows the ANYBUS DATATRANSFER module to exchange data asynchronous with external microprocessors. It has a standard non-return to zero (NRZ) format (one start, eight data, one stop and none parity bit).

  • Page 9: Introduction To An Anybus Application

    480 bytes of output data. If this amount is still not sufficient enough for your application, please ask HMS for a customer specific implementation. Some fieldbus systems can not support large amount of data and can not be configured for the maximum 480 bytes of data inputs/outputs In the following chapters it is described how an implementation when using the DataTransfer module is performed.

  • Page 16 If the application tries to access the DPRAM more than one second the control will be forced back to the AnyBus module. The AnyBus module is indicating this by changing DPRAM-owner from 10 to 01. The AnyBus module waits one millisecond before it starts to accesses the DPRAM again. HMS F Page 16 (35) IELDBUS...

    After the initialisation is performed successfully, the DataTransfer module is in data exchange state, and data can be exchanged with the fieldbus. NOTE! The initialisation is only performed once after system reset (e.g. power up) HMS F Page 18 (35) IELDBUS YSTEMS...

    When the last feature is used, the new data flag should be cleared during the access cycle. In order to prevent deadlocks, a time-out function should be implemented by the application, which will either leave the procedure or re-enter it. HMS F Page 20 (35) IELDBUS...
