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:
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Starting connect to 192.168.1.5:502 Connected to server 192.168.1.5 [ID: E84] Tx:00 00 00 00 00 06 00 03 10 05 00 02 [ID: E84] Rx:00 00 00 00 00 07 00 03 04 BA BE 00 00 Timeout

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.
Dear Amjad. I'm trying to connect Indusoft with DELTA DVP PLC series SV and communication module DVPEN01-SL (modbus TCP) using Modbus TCP/IP protocol (MOTCP). How read DW 2020 or DW180? Is it correct to use this driver?
