Hello,
I have a modbus IO server running on my PC, through labview.
Also, I have a Modbus slave in the network.
I am trying to send some data to and fro master/slave.
I have no trouble while reading the data points on master.
But it does not let me write data to the slave.
I get "No Known Value " in NI Distributed Systems Manager.
Whereas, I can still force these values through NI Distributed Systems Manager.
Can I please get support to fix this problem.
Thank you .

Hi samy123,
I found a solution to a very similar problem to the one you are having. I am going to attach the link of the forum, the solution is specifically on the second page and it also has a video included. It seems that several people were having issues with this.
If you need to see the problem they were having, check the first page.
Regards!
