It sets the degrees one full rotation does in the case of a rotary application. if you had 361 then you were losing a degree every rotation.

What do you have your pulses per rotation set to and are you using absolute or relative move instructions

Is the measurement you're getting the degrees from a physical measurement or is it from the plc?

Even if there was an error in your data type it shouldn't affect the connection. You would simply get nonsensical data back from the device. In sysmac it simply cares about the sizes matching, not the data type layout. I often use byte arrays at first just to test a connection. I would start at a lower level if I were you. Have you tried an explicit message to those instances either from a PLC or a PC? Are there managed switches in between the devices? Are the IPs and subnets compatible?  

In your PLC/HMI project (not your IAG) navigate to the HMI-> Data types At the top click the arrow next to root and select the controller. You can cut and paste the structure from here into your IAG project

I have 3.2, can you share the project?

How are you trying to connect to the SCU? What serial converter are you using?
