I've been looking a while for a solution. But so far no succes.
We have a siemens PLC with a connection throught the ISO Transport Protocol:
ISO transport connections are used for data exchange between S7 stations and for communication with PC stations, S5 stations and third-party systems. Properties of the ISO transport connection: * Communication between stations is based on MAC addresses. * Data transmission with data blocks is suitable for data volumes of up to 8 Kbytes. * Data transmission can take place with the "SEND/RECEIVE" and "FETCH/WRITE" services. * Data reception is confirmed by the partner by means of an acknowledgment on layer 4 of the ISO reference model. * Data can **not** be conducted over a router ( **no** protocol with routing capability, because communication is based on MAC addresses and not IP addresses).
But the S7-node only accept ISO-on-TCP and MPI/DP/MPI. And i don't find another node. Also trying to search for a node wich make a connection through a MAC adress not related to siemens but don't find anything usable.
Does anyone know if there exist such a node? Or how i can make a connection through another way?
Thanks at advance.
