siemens master and other slaves

HI

pls can anyone help,

i have cpu 315 2 dp as master how can i configure 590+ parker ssd drive and sikora spark 2000 as slaves.

With a CPU alone it's not possible. A single Profibus DP line segment is limited to 32 slaves. To go beyond that, you need repeaters. But you are still limited to max 125? slaves on a single network. So you will need more networks (i.e. additional Profibus CPs) and of course repeaters.

Another restriction can be addressable IO area. You are limited to 2k bytes of input + 2k bytes of ouput data.

Hello nanchi;

Both your drive and spark tester technical data refer to them as potential Profibus-DP slaves, and a S7-315-2DP has the capacity to act as a Profibus-DP master. If you have the Profibus communication module for the slaves and their gsd file (a text file that holds information on the DP-slave so the DP-master can configure them), then it is very easy to setup a Profibus-DP network.

For Parker Hannifin 590+ DC drive :

For the Sikora Spark 2000:

Note that the Spark 2000 mentions the Profibus-DP communication option without giving more information, If you want to use a Profibus network with these instruments you should consider talking to your Sikora rep to get more information on the Profibus interface and gsd file  for the Spark 2000.

What experience do you have with Profibus-DP on a S7-300 master?

These videos could provide basic information on integrating new slaves (from their gsd files) in the Step 7 Profibus configurator and setting up a network
