Split from How to set PG/PC interface.

Hello,

is nbot really clear what you mean.

The PLC 315 PN/DP have 2 Interfaces:

PN Interfaces with 2 Ports

1 MPI/DP Interface

in the properties of the MPI/DP Interface you configure if this Interface is PROFIBUS or MPI.

But i don't understand what this have to do with Set PG/PC.

Do you have a PROFIBUS CP in the PC (USB Adapter, or CP 5xxx?) and would connect the PC to the PLC's?

Regards

Christoph

 Hello Cristoph. Thanks for answer.

My PLC (S7300 CPU 315F 2PN/DP) doesn't contain CP (Communication Processor), only CP 343-2 AS Interface and it doesn't support Profibus and Master/slave mode. So I use MPI/DP what supports my PLC for profibus communication.
When I completed hw configurations for master and slave stations I can't download it to CPUs.
I got some PG errors.
I set this for PG/PC:  Simatic-->Options-->Set PG/PC Interface->Intel(R)82579LM Gigabit Network Connection.TCPIP.1 <Active> 

And I got error.

But when I use it for simple PC->PLC communucation (no profibus cable, just MPI) it  works.

Please help.

Could you post some pictures to understand better?
Do you have a programming PG?

good luck.

Hello,

and which error you get?
A error that the download is not possible?
Or is the downoaded config not running an this is the error?

You mix a lot of different things here and is not really clear which is your problem.

but the problem is missing!

which problem you have ?

from th first view:

between PLC and CP are some other modules, why they are not in you HWConfig?

the diagnostic messages are not matching the projectconfiguration, can it be that some other project is stored on the PLC?

In my last visit to diagnostic buffer I had this problem:

Event 5 of 10:  Event ID 16# 4304
STOP caused by PG stop operation or by SFB 20 "STOP"
Previous operating mode: RUN
Requested operating mode: STOP (internal)
Incoming event
12:39:20.718 AM  01/26/1994
(Coding: 16# 4304  FF84  0000  0000  0000  0000)

And I thought to I need set some other option in PG/PC interface.

Of course, some program was downloaded to PLCs before this profibus hw configurations.

why you think you need anothe PG/PC Interface?
This interface is used to communicate between PC and PLC!

And you can go online an read the Diagnostic buffer, so that is not your problem!

i ask you again! What exactly is you problem?
Have you load the project you attached to both PLC?

Why there are modules between the PLC and the CP which are not configured? This can the reason for a lot of the diagnostic messages you atach!

You should try this steps:

1.MRES (reset to Factory) on both PLC's
2. insert the pluged modules between PLC and CP in HWConfig so that the config matches the real one or remove the modules and plug the CP directly after the PLC like you configured it
3. download the project to both PLCS which are have no older program or config on it
