Hello!

I set S7 communication with LOGO! as client and S7-300 station as server and it work well.
Is it possible to set S7 communication with LOGO! as sever and S7-300 as client?
I tried to do it, but I failed: it seems STEP7 nothing knows about VM memory of LOGO! (I addressed to VM memory of LOGO! as DB1.DBB0 and used standard blocks PUT FB15 and GET FB14).

Best regards.

Give us more info!

What equipment are you using? (part numbers)
What network are you using?
What software version are you using? (Step7/LogoSoft/etc)

short answer
No

I don't think that it is possible to use the LOGO as a server. Only client

Help to find the document «EN_LOGO! -S7-300_communication». Thanks.
