  • Page 18: Introduction

    This chapter contains a description of the characteristics of the BL××-gateways for PROFIBUS-DPV1. As the DPV1-gateways for BL20 and BL67 do not differ from the DPV0-gateways in their technical data, their connection options (field bus, power supply), their mechanical mounting etc., only the special features of the DPV1-gateways are described in the following.

  • Page 19: Function

    The gateways regulate the process data between the I/O level and the fieldbus, and generate diagnostic data for the higher-level master. Information is made available to the software tool I/O-ASSISTANT via the service interface. Note BL×× gateways can only be used as slaves. D300956 0210 - BL67/BL20 - DPV1...

  • Page 20: Important Notes Concerning The Dpv1-Gateways

    BL××-DPV0-gateways can not be replaced by the new DPV1-gateways. The devices have differ- ent indent numbers and different GSD-files. Diagnosis Note The new DPV1-gateways allow the DP-standard-diagnosis according to PROFIBUS-DP specifica- tion. The diagnosis is not compatible with the diagnosis of the DPV0-gateways.

Additionally, the status message is independent of the actual number of modules in the station. Pending diagnosis messages are indicated by "1".
