Beckhoff: connection between BX9000 and CX9000

[staachu]

Hi everyone,

I'm writing a simple application for my study project in ST language and I'd like to send and recive data (variables) between two Beckhoff PLC's: BX9000 and CX9000.
How to do it via Ethernet connection?

Hi,
you can use the ADSREAD and ADSWRITE FBs from the System.lib.
Check out http://infosys.beckhoff.com/index.php?c ... ad.htm&id=

I use this for communication between my CX1020 and 3 x BC9000.

Hope that helps.

Thank you, this could be very helpful for me.
I've got one question. Where can I find IDXGRP and IDXOFFS?
The help file says this values are to be found in the ADS table of the addressed device, but I don't know where to find it.

Thank you in advance.
Best regards
