Hello . I want to change control from contactor to inverter for pump. I am working with 315PN-DP controler,  6SL3210-1KE21-7AF1  with  software  Step7 V5.6 and Simotion Scout V5.4 .

I ve added drives in step/scout few times but mainly DP type. Today I am trying to add PN drive. I watched the movie showing proces.

When i get to the point (8:20 )where after assigment  of IP  I should connect to the drive but  I am reciving error that connection is not possible.

I see that I can ping unit from PG, when I disconnect profinet cable both PLC and VFD gives communication errors  so it looks that it is open for communication .

I can upload drive from online device  to Scout project  but can not assign drive as declared in step 7 new drive.

I ve tested  connection with Device/USB but after marking found drive in accesible nodes and getting in connect online drive  i  get window  with inactive newly created PN drive  , only possible to mark other DP drive... with red color that it is wrong selection.

When I try to do this via profinet i get just error: Connect to selected  target device not possible.

 As mention i ve did configuration as in movie. I did assigment of unit name and ip adress in step7 , same in scout... checked few times  connection between scout , device but ...without success.

Any advices what  am I missing?

Sorry I cant add second picture - some limit in the forum.

Hello ChristophD.

I ve tried two options.

1. USB cable where I can see inverter in Accesible nodes. When I mark it on the list and press button Connet to target devices  I  get screen as in first post without possiblity to choose this inverter from list to assign it to found device.  I marked with arrow on the picture  name of the drive which is grey and from some reason it is not possible to assign.

2. I connected online via ethernet.  I prepare Hw config and topology in NetPro where PLC on second port is connected to XB008 switch  3 port and inverter first port is connected from 5th port  (XB008) .

During trials I was connected to  one of the ports of the switch so not directly to the inverter.

Davinator: not sure ...any advices will be appreciated how to check if it will be ok ?

When I just accept inverter to project ( without assigning )  i see it as 4.7.13 ver

I am attaching picture of rating plate

Ok , do this : after you get the error message that you posted, in the bottom window there must be some other additional informations. For your informations it is the menu with the "red bomb" icon.

I am sure that your issue is described there

Hello . Thank You for Your replies.Generally there is information that  I should check interface setting. I am attaching pictures of  buffer.

And another atachment from USB connection trial . I am confused that scout wants to connect to other inverter than selected in left side window.  It dosen' t see  it as a proper inverter. It tries to connect to G120 with CU 250 with profibus ...and returns with fault that drive is incompatibile.

I checked  , IP adress -ok , name - ok ,  name /model  also G120C_PN, as well as firmware version  4.7.13  uploaded ( when I do accept drive  )  same . I also have  4.7.14 in catlog   so it  is not somethineg newest... Not sure if  there is newer version that 4.7.14 and it uploads it as 4.7.13  with faulty behaviour ?

EDIT . I checked parameter r18  in inverter and get  value 4715221 what suggest that it is version 4.7.15 which is not installed on my PG...

Wonder if it will be available for scout v5.4 or I will have to update scout.

Well, in the last screen shot the problem is trivial  : you are trying to connect to a G120 DP and you have phisically a G120 PN

They are different
