Applies to MICROMASTER 4 with PROFIBUS Optionsmodule

Routing between PG/PC and MICROMASTER does not work although the PG/PC interface is set to ISO-Industrial Ethernet. What can I do?

To allow communication with Routing change the PG/PC Interface to "TCP/IP".

Open NetPro in your project.
Attached you find the procedure how to do it.

Ensure that your MICROMASTER and your PG/PC is connected-up as shown in the diagram



 


Next, your PG/PC must be assigned as shown in the next three screen shots.

Right mouse click on PG/PC an choose assign PG/PC.



 


Choose your TCP/IP interface in tab assignment.



Checkmark S7ONLINE Access and confirm with Ok.



 


Now, the ROUTING should be active (this is shown by the yellow line).
