Hi sun7, i agree with J_Bell: i used System Bus and Terminal Bus over the same cable sometimes (just for a cheaper solution client absolutely wanted). But never cretaed a ring between the 2 different network expecially if you have time synchronizazione broadcast messages and harder if more PCS7 with different version, that should cause a lot of trouble. At the end, make a ring between System Bus and Terminal Bus could cause more trouble than benefit. The other solution, if you really want mix the network, could be using a ring with scalance with ring manager feautre, and put all devices on the same network. In this case be sure what message you need over the network, expecially for broadcast fot time sync and thirdy part cmponents. Hope can help a lil Regards |
