What is the maximum possible data exchange limit for Modbus - Profibus gateway LUFP7.
The Profibus-DP network is totally separate from the Modbus network. The frames on a network are not directly “translated” by
the gateway LUFP7 to generate frames on the other network. The exchanges between the content of the gateway’s memory and the
Modbus slaves make up a system which is independent of the on which is entrusted with managing the exchanges between this same
memory and the Profibus-DP master. System guarantees the coherence of data exchanged within the shared memory.
Below are the maximum limits of data exchange
1.244 bytes maximum for Modbus Input data (Responses to read requests)
2.244 bytes maximum for modbus output data (Write requests)
