Error Communication Failed

[Gabor]

Hello
I am new to this, and would need some more help: I try to read a device using modbus TCP. I can ping the device, but cannot read any registers from it. Whatever I try, I get Error: Communication Failed message in the Line Log/Stat. With localhost + ModbusSimulator the project is working, but as soon I try to connect to this device, I got error. I read it somewhere here in another topic/comment that the Byte Order can affect this..? Or it has nothing to do with Communication errors.. I tried many things: connected directly, disabled firewall, and yes – watched the modbus videos, etc.
Any advice would be appreciated. Will upload photos and logs tomorrow. Thanks, Gabor
