New Functions in Version V4.02
Configuring the DP/PA Link
The DP/PA link is a DP slave which for its part (acting as a kind of ªmasterº) ªopensº a PROFIBUS PA for connecting PROFIBUS PA devices.
The PROFIBUS PA must be running at a transmission rate of 45.45 Kbps when you connect PA devices.
To configure a DP/PA link, proceed as follows:
1.Install the optional package SIPROM; this will enable you to configure the PA slaves from the ªHardware Catalogº window at a later stage. (The PA slaves are located in the ªPROFIBUS PAº container.)
2.Configure a DP master system.
3.Drag the DP/PA link (IM 157) from the ªHardware Catalogº window (ªDP/PA Linkº container) to the DP master system.
4.Select the DP/PA link; the DP slave structure will be displayed in the lower section of the station window.
5.Slot 4 represents the ªmasterº for the PA
6.Click the ªPROFIBUSº button and select the subnet with the transmission rate of 45.45 Kbps (already preset).
7.Then configure the PA devices.
(Proceed as for DP slaves: Use drag & drop to transfer the PA devices from the ªHardware Catalogº window in the ªPROFIBUS PAº container to the PA subnet.)
