Hi am using a scaling block for a analog input 4-20ma seem pretty straight forward, but the problem i have is in block settings the input is not being read therefore i cannot see a scaled output.

Have i forgot to put a a simple setting.

Thanks

Has the analog input been enabled in the properties dialog box, assuming you are using Logix5000.

Is your subroutine being executed?

Is the input wired correctly?

If you can zip your program and attach it to a post that could help.
