RS-485 interface module PD667

PROFIBUSPROFIBUS DPpower

Profibus DP-V0 Essential Features Master • RS485 interface for Profibus • Light-Link interface for P-NET • Advanced internal self testing • Wide power supply range • Wide temperature range • LED for power On • LED for Error indication The PD 667 Profibus DP master interface offers a simple means to utilize Profibus devices within a P-NET control system. This opens the possibility to integrate devices that are only available with a Profibus DP interface, seamlessly into a P-NET system. It uses a BM 002 base module. Communication The PD 667 module contains an RS485 interface for Profibus and a Light-Link interface for P-NET. All data exchange with the Profibus slaves is performed to/from memory arrays in the PD 667. P-NET devices on the network can read or write into these areas and in doing so read data from or send commands to Profibus slaves. Limitations The PD 667 implements the essential features of Profibus DP V0 master functionality to enable two-way communication between two fieldbus types. Major limitations are: No multi-master, no token handling procedures, max. 19200 bps, max 8 slaves, no sync and freeze, no slave group, no 5-volt supply for termination. Configuration The module itself does not require any programming. Profibus network settings and slave configurations are entered into a table via VIGO. The PD 667 supports (per Profibus slave): 0..244 bytes of input 0..244 bytes of output Full data consistency Input and Output slaves / Input only slaves / Output only slaves Diagnostic data, automatically and upon request Signal for new data / new diagnostic data available Protocol status.
