What Connectors, Pin Out And Mandatory Signals Are Used?

1.	What Connectors, Pin Out And Mandatory Signals Are Used?
Answer» The PROFIBUS Standard does not SPECIFY an alternative to the 9 pin D-SUB connectors, but it is often necessary to have ALTERNATIVES AVAILABLE. The test specification for DP Slaves defines: Alternative connectors may be used. No special CONNECTOR is defined. But if the device with these alternative connectors should be certified, it must have all the mandatory signals of the PROFIBUS D-SUB connector available. Furthermore, you should take into consideration for high speed usage, that some additional components should be used in combination with the D-SUB connector, or any other one. These components (R, L, C) are specified into the Implementation Guideline for PROFIBUS-DP, and are explained in detail including sample circuit diagrams in the new PROFIBUS-DP BOOK (The Rapid Way to PROFIBUS-DP). This book may be ordered from your local PROFIBUS organization. The PROFIBUS Standard does not specify an alternative to the 9 pin D-SUB connectors, but it is often necessary to have alternatives available. The test specification for DP Slaves defines:
