Hi,
I'm trying to connect Indusoft with DELTA DVP PLC using Modbus TCP/IP protocol.
The comm. driver gives read status error: (-15) which is: "Timeout Start Message"
It means Indusoft isn't reading any response form PLC,,
But when I looked the TX/RX frames log window, I found this:

This log confirmed two things:
1) There is response (Rx frame) from PLC !! :confused:
2) The value of reading is (BABE)hex which is the exact expected value that I already put it in the PLC memory..
I'm not sure why time-out is occurring after each request ?!
Waiting your advice.
