Which driver are you using?

[Darrell]

Ive done this by adding a basic button and a textbox using the micrologix driver


add this code to the button substituting this Ip with you own

EthernetIPforPLCSLCMicroCom1.IPAddress = "149.139.119.15"
TextBox1.Text = EthernetIPforPLCSLCMicroCom1.IPAddress


you can also add a button to change the IP from what is displayed in the textbox.
add this code to a button

 EthernetIPforPLCSLCMicroCom1.IPAddress = TextBox1.Text

-Right click the AdvancedHMI project in Solution Explorer and select Properties
- Select the Application tab
- Click the Assembly Information button

You should see the more detailed version number. The latest version is 3.9.8

If you don't have the latest, then download it and see if the problem still exists.

I did find the new driver had a problem with writing to bits. This will be fixed in the next version. A new version should be available within the next few days.
