[?]: S7 communication via radio modems

Post by Homeroid_BL » Wed Jun 02, 2010 4:59 pm

Hello!

Is there anyone here who managed to connect two S7 PLCs via radio modems?
Please do not answer only in theory.
If so, please tell me which cables are used (suppose PPI/232, which DIP settings?), which modems are used, which protocol is used.
Also, attaching code of both PLC will be appreciated (only communication blcks).

Thanks and best regards.
