Simatic 155U IM308 Profibus Problem

[isteak007]

The code in FB7-NW5 is sending your PLC to STOP. Don't you have a version with comments in it? Also post your COM Profibus configuration file.

I dont have the file Comments in it.
i will download the com profibus configuration Tomorrow.
Why my Address 14 and 14 is in another profibus network?
and i got error in both address 14 & 15
pls see the images (Online profibus)

Did the machine work after you moved it from Africa or are you still commissioning it? Give us a short schematic of you PROFIBUS layout. You probably have a section with a cabling error in it if it all worked before.
I don't understand the images you posted. They are from an S7-300 PLC??
Is the topology from a diagnostic repeater? If it is I would not trust it, the results can be a bit misleading when you have electrical problems on the PROFIBUS,

We bought benninger machine from South Africa.

The pictures are from Simatic manager.
This is an S5 network. Ignore the pictures.

Check the profibus wiring for correct connections.

So you have never had the network running correctly in your plant?
What checks did you do before turning the power on?

 

[isteak007]

When did the network fail?
was anyone working on the system at the time?
How many stations are there?
How/what did you check at the stations
Were there any Fault LED's on at the stations/
Please check the IM308 LED's with the error indications in the manual
Post the IM308/Profibus configuration here as Jobbe suggested.

When did the network fail? We bought this old benninger machine form South Africa Now we are setting it up.
was anyone working on the system at the time? No
How/what did you check at the stations. i chek all the physical address and form Topology Network i got error in address 14 and 15 other station is working fine.
pls see the image in image you will see first two is a cross marking

Once again ignore the images these are from the Simatic Manager.
Your network is an S5 network.

Check the LED's against the error codes in the manual.
Did anyone check that the network was working before the machine was shut down?
Check all connections and station addresses.
Also check profibus cable for damage.

But Address 14 & 15 address's device ET200B Al/8 Also in Stop Condition too when they are connected in address 14 & 15.
Machine was in running condition when it was last shut down in south africa

The fault is probably with stations 14 & 15 BUT ignore your pictures - they are from Simatic manager
Check the profibus cable.
Check the profibus connections - take the plugs apart and check
Check the profibus termination resistors.
Goto the stations and physically check all of the above.

Pls check the photo of diagonestic report of address 14
pls check the picture

Why do I need to check the picture it is from Simatic manager.
Your network is a S5 network.
Jobbe already stated that it can not be trusted.
You need to go to the stations and check the connections, the station id's, the cables for damage, the termination resistors etc.
Take the plugs apart and check the connections!
Check the plugs for damage.
Power the stations off and on again!
If it was running ok before the plant was shut down it should run ok now!
