Hi everyone, I need help with a project where I have a LOGO! Siemens 6ED1052-1HB08-0BA0 that communicates the states of inputs and outputs via Modbus/Ethernet with Labview, I wanted to ask you if it is possible, using labview to check the state of a Merker, then to virtually change the status of the Merker from 1 to 0.

So you need to communicate over Ethernet Modbus. Go to VIPM.io and do a search for Modbus. Here is the link to the NI Modbus package: https://www.vipm.io/package/ni_lib_modbus_library/
Thanks for your answer. I have already established the modbus connection with the plc, in fact I see the inputs and outputs in labview. I wanted to know if I could instead of reading, write boolean values. Then change a Merker from 0 to 1.
Good you have done. Can you please show me the way you have done made LabView to communicate with Siemens v8 logo through Modbus
Of course, once you have opened your Labview project, on the project view right click on it go to new and there will be the Modbus/Modbus Slave option, it will take you to a screen where you will choose whether the connection is TCP/IP or Modbus RTU . Then enter the required labview parameters. Once done, when you press ok, a screen will open automatically where you choose the Modbus addresses to read from them and always from that screen you will choose whether they are data to be read or written. I hope I was helpful.
