Communication with Yaskawa drive

I have to set up some commands to communicate with a Yaskawa V1000 drive. It has a SI-EN3/V Ethernet/IP interface card.

I added a Generic Ethernet module (ETHERNET-MODULE) to my Studio 5000 project. My question is how to set up the Connection Parameters in the ETHERNET-MODULE.

I got the user manual from Yaskawa. It says that "Basic Speed Control Output" is Assembly Number 20 and 4 Bytes. So, I put 20 in the Assembly Instance Output of Connection Parameters in the ETHERNET-MODULE. I put 4 for Size. Is this right? See images below. Thanks in advance.
