EDS file Class 1 Data Type

Hello 

We are developing our own EtherNet/IP device (Relay). We have the stack running and all Implicit and Explicit messages work well.

My question is on the EDS file and the data types:

I’m trying to get the input and output tags of Class 1 messages (Allen Bradley 1769-L16ER-BB1B in Studio 5000) to match the data type, stipulated in the EDS file.

Seems like I can't paste images here, I will try to explain from my EDS and Studio 5000.

1. In my EDS, Connection Manager - Exclusive Owner D, T->O Format refers to Assembly4.
2. Assembly 4 refers to Parameter 1.
3. Parameter 1 has a Data Type of UINT (0 - 65535).

1. Then I Imported this EDS into Studio 5000.
2. I select Connection Manager - Exclusive owner D.
3. Then I can choose between SINT and INT, both of these data types are signed.
4. How do I change the EDS file so that Studio 5000 will ONLY give me UNIT as an option?

Help will be appreciated. (EDS attached)
