Siemens S7 To softing S5 PC link

[Bryan Smith]

Hi I am wanting to create a link between an S5 PLC and S7 PLC using the S5 PC link from softing linked to the S7 ethernet port. Has anyone done this?

You don't tell which kind of link and which interface in the S7 and the S5.

Anyway, I have done something similar with a S5Lan++ link that I bought here.
It was connected from a CP443-1 via the S5Lan++ to the 511-interface of a S5115U (95U and 948U did also work).

I used put/get -functions in the S7, the S5 has to be passive.

The 511-interface is not very performant. The throughput at best is 500ms, if you have compact data <= 64 Words, one put and one get telegram.

Thanks Kalle I am using a soft PLC winLC RTX so the connection should be the same, do you have an example program for the S7 400?

I don't have the program anymore, but it was only one call of the FB GET and one FB PUT. You should find examples on the Siemens supplay pages.

I did only use DBs in my prog., but Markers was allowed as well.

Be sure that the IP-adress/subnet fits.
Make an active connection in the S7.
If you get trouble, it is likely caused by the TSAP (RACK/SLOT number) in the connection setup. I cannot remember what I used, but it could be it is mentioned in the PC-Link docu.

Good luck!

Thanks Kalle

Can you remember if you made an actual S7 300 connection in your hardware or was it an unknown connection?

 

[KalleOlsen]

I made an 'unknown' connection.

 

[Bryan Smith]

Thanks, and did you have to send parameters do the Lan++ via the parameter DB?

 

[KalleOlsen]

No.

I used a setup program to configure the IP/subnet address.
I think it was a utility CD in the box with the LAN++.
...
Shouldn't need to adjust anything else, the 511 protocol is fixed according to speed and character format.

Edit: The setup program is called VCOM.
Here is the LAN++ manual:
