No both are not connected at sametime.

I unplug one and connect another to my PC..

It is not PLC , its a drive ....

The PC connection is not the problem, I want to know the profibus connection.
Do you have only the drive and nothing else connected to profibus?

Hi,

first Screen in Post #36.
On the SIEMENS CP the Option "is the only master on bus" is set, and the Screen in Post #37 show in the LifeListCommand 2 Entries.
This 2 Entries i think are 1 and 2 like the CP5711 dialog in post #36.

Check if there a option "master on the bus" is availabe for the AGLink, the MCT10 is a passive Slave and needs a PROFIBUS Master for communication.
The SIEMENS CP support this Master option but the AGLINK?

Regards
Christoph

In AGLink there is no option available under S7-Netlink USB to set my PC as master..
I also had a doubt that how to set my PC as master when communicating Accon-Netlink USB compact via AGLink?? I think my drive search for Master ...
but in AGlink there is no option available to make my PC as master..
could you please check it ?

 

[Rainer Hönle]

Only for testing: do you have any other master (for example a PLC), which you can connect to the bus?

 

[Rainer Hönle]

It is not an problem with ACCON-AGLink, it is a problem with profibus an ACCON-NetLink-USB compact. So we can use ACCON-AGLink only for testing and verification.

No i dont have PLC.. is there any other way to do ?

 

[ChristophD]

in post #34
"any plc can be detected by accon netlink usb compact , if it uses the simatic s7-200.."

So I think the Adapter "ACCON-NetLink-USB compact" works correct if a active device is connected.

Hmm no PLC? But you have a SIEMENS CP on your side? Can your make a test with a connection between SIEMENS CP and NetLink?

 

[natarajan]

I dont get your point on "can you make a test with a connection in between Siemens CP and NetLink" ..??

connect both, the SIEMENS CP and the Netlink , to the drive.
with a little luck the SIEMENS CP take the Master Role on the PROFIBUS and the NetLink find the devices.
That's the only idea i have on this time

 

[natarajan]

My drive doesnt have facility to connect both profibus adapter ...

 

[ChristophD]

WTF? Which drive do you use? MCT10 ist the Software for the drive but not the drive type!
Why you can't connect it, one Connector from SIEMENS CP to NetLink, an the on Connector from Netlink to the Drive. Where is the problem?

I am using Danfoss FC102 drive ... MCT10 is the software for the drive and I know using this MCT10 we cant access through Accon Netlink USB compact....


MY question is :- why I am unable to detect the FC102 drive using Accon Netlink USB compact ???

 

[ChristophD]

because the Accon NetLink USB Compact support the following PLC's: S7-200, S7-300, S7-400
Other devices can be work but is not a "Must"

 

[natarajan]

so does it mean, it wont work with Danfoss FC102 drive????

yes i think so.
in the mct10 manuall you find the followed :
The following Master class 2 cards are currently supported from Siemens:
• CP 5411
• CP 5511
• CP 5512
• CP 5611
• CP 5613
• CP 5614
• CP 5711

In the Manual of the NetLink i can't find any word to the supported Master Classes.

 

[natarajan]

ok I will try to connect Danfoss FC102 using one of the ( #58 ) adapter mentioned with Accon AGLink and check whether it is working or not !! ... I ll give a try ....

because the Accon NetLink USB Compact support the following PLC's: S7-200, S7-300, S7-400

1. Accon NetLink Supports mostly all Devices that are Supported by Siemens CPs - because its just an USB<->Profibus Converter
2. AGLink supports ON TOP of Profibus the device specific protocolls of LOGO,S7-200,300,400,1200,1500 AND some SIEMENS driver protocols
3. natarajan can't find the Profibus-Device using the USB Compact <- PROBLEM1
4. natarajan isn't even able to connect to his plc using the USB Compact (what is meant as a test - because this is the main usage situation) <- PROBLEM2

as i understand it correct the danfoss driver isn't speaking a siemens kompatible protocol - so it will not work (i don't know where natarajan got the information that it should/could)
but the main problem is that his USB Compact isn't able to see anything on profibus
