My PLCs are defined in 2 different projects which are both "member" of the same multiproject, and I have made the merge of the networks from the different project in NetPro, so this should also be OK. The connections between the PLCs are also merged in NetPro and should also be OK, but when I click on the connection in NetPro I get the following info for the S7 connection (see attachment) which does not include the LADDR, and I therefore don't know what to address to use when setting up the AG_SEND and th AG_RECV blocks? Any one who can help? Cheers Jesper Attachment Netpro.jpg (235 Downloads)

What you can useviaS7 connections areGET/PUT, BSEND/BRCV and/or USEND/URCV and below are a few example links: Sample program: S7 communication with the blocks SFB14 ("GET") and SFB15 ("PUT") with S7-400 Sample Program: S7 Communication with blocks FB14 ("GET") und FB15 ("PUT") of the CPU 317-2PN/DP How do you program communication blocks FB12 "BSEND" and FB13 "BRCV" for data exchange in the S7 program of an S7-300 CPU? How do you program communication blocks FB8 "USEND" and FB9 "URCV" for data exchange on the S7-300? As you have a PN port onyour S7-300 instead of a CP, you could also use so called OpenIE communication in it (not configured in NetPro of the S7-300), but you'll find that usingS7 connections is the easier choice. Last but not least, have a look too at the CPU-CPU communication with SIMATIC controllers (compendium) which is an excellent reference to have when working out what is and what isn't possible concerning this subject. I hope this helps
