All,

I have 2 6ES7 315 - 2EH14 - 0AB0 (v3.2.11 and v3.2.6) networked using profinet.

I want to use I-device to communicate some data. (2 words). i have created the GSD file and added it to the project. When i added the GSD i changed the name to make it match the name of my 2nd CPU. Had to do this to have the BF and SF faults to go away. (according to FAQ on this site)

I still can not communicate.
I am not sure if i am supposed to do it through process IO or using SFCs(14 and 15). I tried both but cannot send any data over yet.

Can  anyone give me some more information? I have looked through the FAQ and those explain how to do it using TIA portal, but i need to use Step 7 manager to get it done.

Thank you for all the help!

hi Koenraad,

the I-Device is connected to the IO-Controller, is it? so BF and SF is not on. Do you have the Profinet-System-manual, where the I-Device-functionality is described? Chapter 4.8

SIMATIC PROFINET System Description

Try to use Inputs and Outputs inside the process-image. 

hope this helps,

 Hi MopS04,

Yes i have used this manual to configure the PLC's. 

I created the configuration on one controller and then i went to the I-device Tab and created a new transfer area. 

Then I created the GSD and brought that in into the hardware config of my other PLC. I had to adjust the device name of that GSD to make the bus fault go away. But now I still can not send over data as shown in the manual. The transfer area type is Application. I can not chose IO transfer area on this PLC.

I have added a screenshot of my hardware config in the Master controller.

What does it mean when my addresses are in Cursive? 

On both PLC's i assume that the Input address is 256 (shown in screen shot)

So i had the following on the I device PLC:

A M0.0
A M0.1
= Q256.0

This should mean that I256.0 is one on the master controller right? (according to manual...)

Thanks for all the help!

yes this is right

BUT:

256 is a adress outside the default processimage!

so if you not extend the process imge size of the PLC's then you must acces it with PO256.0 or PI256.0 !

Or you expand the Processimage in the PLC Porperties of HWConfig.

 Christoph,

Thank you for this information!
I changed the addresses on I -device side and Master side to 50. Then i can select the OB1 Process Image.

But the communication still does not work when using this process image.
What does it mean when the address is in cursive in the hardware config? 

Added screen shot in attachment.

Thank you.

Hi,

adresses always cursive in the HWConfig.

Christoph

Hi,

On the screenshot bellow. I have addresses in Cursive and others are not.

What exactly does that mean?

Thanks.

Solved

Error OB's need to be loaded in order to have it working.

First generate the I-device controller hardware config.
Then set the transfer area in the I-Device Tab. Make sure the addresses are in the default process image if you wish to use them this way. 

Save and compile then download to I-device.
Then generate the GSD file. 

Go to the IO master controller HWconfig. Insert the GSD as a profinet slave.
If the controller is in the same project then make sure that your I-Device has the same Device name in this HW config as the I-Device device name in its HWConfig.

Adapt addresses so they are in the default process image (if you wish to use this in this way).
Download config to PLC.

Now you will have BF and SF's and only one plc can go to run, when you reset the other one it poets the other PLC in stop. This unless you load the OB82 -85-86. You need to do this in order to have the communication working.

This worked for me. Hope this helps anyone else having similar issues.

Thanks for all the help.

HiKoenraad.Cannaert,

I have the same problem with you. When one plc stops, the other will error. Can u tell me how to use the OB 83-85-86 to make it work? Thanks so much.
