Read and write register value from HMI and LabVIEW

[A.Yaghooti_Nia]

Hi everyone,

I'm facing a serious problem in my LabVIEW project, I'm trying to read and write a specific register value from multiple devices at the same time.

For example, I wanna change the value of 400001 MODBUS register from HMI and LabVIEW at the same time. The problem is when I put a numeric control

to my program and wire it to MODBUS variable and set it to specific value, I'm not able to change the value of register from HMI anymore because 

the numeric control is continuously putting the value to register and blocking HMI to put value into register. Also I wanna see real-time value of register

in numeric control(I did it by defining a local variable but still have the main problem). Can you help me by suggesting a solution or an example program?

Thanks in advance,

Well honestly this sounds like a very basic LabVIEW programing task.

But without seeing your code we can't tell you what you are doing wrong.
