hi there! i am trying to read modbus registers in M340 PLC from a Turck BL20 Gateway. I have done this with a Emerson Gateway and everything worked good. I configured the Read_var block as i did before. but i don't get any data from the GW, have anyone here done this before? or at least read from a BL20 GW? no mater which PLC you used.. i want to know if i have to configure something in the BL20... many people have said me that i don't have to make anything in particular in the GW, that the device put the data automatically to be read.. any idea where could the problem be?

The Turck BL20 appears to have several methods of defining the unit IP address - rotary switch, PGM mode, DHCP as shown on page 4-10/11 (paper, 37-38 pdf) in the manual here:

Is the addressing set up for what expect it to be?
Can you ping it?
