I have 2 nos S7-300 PLC units and 2 nos WinCC HMI PC. All of these are connected over PROFIBUS. I have recently installed SARTORIUS make X4 controllers (weiging and batching application) which are having PROFIBUS option cards. I want to log data from these controllers into HMI and also need to generate some screens for changing reciepe. Pl suggest me how to proceed.

Software available with me:
STEP7 for S-7 PLC
WinCC configuration version.
Is there any other software needed. Pl tell me.

Please help me by your kind suggestions,

Thanks

 

Isn't there any solution for the situation? Where can I get help, please help

 

Well, I don't have Siemens S7, but I have used Siemens PDM and Sartorius load cell electronics.

The implementation effort to add a Profibus device must bear some similarity to dealing with a HART device in PDM.

When connecting to a HART or Modbus device in PDM (a component of STEP 7), one must create a project and define the physical connection and the protocol. Has that been done?

Section 10 Fieldbus (Profibus) in the Sartorius X4 manual provides tables of address registers for write data and/or read data. One assumes STEP 7 accesses those address registers for the needed data.

Providing the forum with a description of what you've tried and where you've stalled might generate more activity than asking for a tutorial.

Your best bet is to get hold of the manual for the profibus option cards. It should give you info on how to work with SARTORIUS.

Generally what happens is you'll assign an unused Profibus address to the card and then using Step 7 add the controller to your profibus network. When you've added it you'll get some PIW PQW addresses which you use in your step 7 program to talk to the SARTORIUS controller.

Hope this helps..

 

David and Rich,

Thanks for your contributions and support. In fact I have now obtained GSD file reqd for integrating the Sartorius X4 controller in Profibus network. Now the controller has been added to the already existing network and it is visible. In fact SARToRIUS manual on Profibus option card has explained the procedure in detail. It already takes into account the connectivity with Siemens PLC. Thus it has helped me to transfer data to S7 plc. However now I am struggling to get all data as per my need to the PLC.

Keep me posted for any further info.
Bye
