Hi I am trying to establish comms between Mango M2M (modbus TCP master) and OpenAPC (modbus TCP Salve). but so far have no any luck. I tried to tracking the data using modscan I found that : 1) the Transaction Identifier is always 0000 (not replicating the master) 2) the Message Length is 2 bytes smaller than in the actual response value. could this have happen due to data string being 32bit ???
However what is your recommendation can you please please help me
