Kepserver Ex Codesys connection - Device is not responding in event log

I just connected Codesys to Kepserver via first running a virtual PLC via codesys control win and running my program. Then I created a Codesys channel using all the general settings. When adding a device i changed the type of communications in use to CODESYS V3 Ethernet, the address when connecting to the device (Address Type: Logical Address/PLC Name and also the Logical Address to my Device Address from Codesys. 

But after running Kepserver it tells me my Device is not responding. I have looked at the other thread and since I am new to Kepserver and Codesys I don't really understand what is going on. The addresses for my tags should be right. Any help would be greatly appreciated. I have added lots of screenshots just in case. If you need any more let me know.

Hello,

Are you able to find the device using Device Discovery? Right-click on the channel > Device Discovery.

Based on the screenshots (since you aren’t able to connect to the device), here are some important things to check as per the article below. Additionally, you can use the Wireshark tool to capture data and see what is happening at the wire level.

Yes, the device is discoverable. But even then the values for the tags are unknown and the quality bad. I will try the other options and I'll get back to you. Do you think it could be a problem with my address for the tags by any chance based on my screenshots?

The address looks good, but to avoid any syntax issues, I suggest using the Auto Tag Generation feature of the driver.
