Trouble with Cia402 drive configuration was created by peterpan

Trouble with Cia402 drive configuration

Category: EtherCAT

I've been working on an EtherCAT build for a couple of months now, and wanted to avoid posting here, but it seems I have hit a wall.
For some background: I am completely new to LinuxCNC but wanted to build an EtherCAT AXYZ cnc with Cia402 drives. I got an EK1100, EL1008, and EL2008, and my brother gave me a ClearPath-EC Teknic Cia402 (CoE) drive. I had a raspberry pi 5 available, so I am testing my configuration on that right now. I used the Pre-packaged rasp-pi install (Debian 12) with LinuxCNC from the linuxcnc website, and had very little trouble following Rod's installation from repositories. From there I had a lot of trouble, but got a configuration based off of the sim.axis config working with the EtherCAT slaves, and was able to test I/O with no trouble. 
Now, as I am attempting to incorporate the drive, but I can't get it into the OP state. The EtherCAT master recognizes it, and I can define pdos, but sdo 0x2000 and 0x2011 seem to just not exist, which I currently think has to do with the problem. I'm still having trouble wrapping my head around this, so let me know if there's anything else you need to help me. I would really appreciate the help!

Here are the .ini and .hal files.
The static IP of the RPi is 10.10.10.100 - I can ping the Mesa card from the terminal.
