Monitoring SDO value

The situation is as follows: There is an option to set SDO values at the start of the EtherCAT module. Is it possible to monitor SDO registers for reading? For example, there is a C2000 drive and an EtherCAT manual. Let's say you need to monitor register 3026:01, which is the input status, or DC voltage 3021:06. Ideally, these registers should be in the PDO by the manufacturer, but for some reason, they are not. Therefore, simply writing them into the XML in the PDO section doesn't work (it just doesn't work). In TwinCAT, it is possible to track these states (and accordingly, they are not PDOs) (this happens not as fast as with PDO variables, but this possibility exists). It would also be nice to change these as well, for example, changing the value of register 3026:41, which is for output. For now, I can simply set it in the EtherCAT terminal with the commandbut this is still a workaround. Perhaps it is necessary to work more with the pure EtherCAT library and refine this function.
Does anyone know how to solve this?

Admin, maybe this could be moved to the EtherCAT section.

Since no advice was forthcoming, I decided to develop my own component that can monitor and change SDO parameters.
Essentially, this will be a similar component to the one currently working with EtherCAT LinuxCNC but specifically for manipulating SDO data. Unlike the existing driver, it will work with YAML, which is much more convenient than XML.
An approximate example of such a file will be attached. If there are any suggestions, I would be happy to hear them.
I think I will start this week and finish in about a week. Later on, it will be possible to integrate the old functionality for working with PDO.
Although the current one works well, it has its drawbacks.

PS Admins, please add yaml and yml formats to the editor.

So, I uploaded a working version for interacting with SDO. With this utility, you can read the status of SDO registers. I haven't yet implemented the online value writing—this will be the next step. It's not as straightforward because you can't attach it to an address like with PDO. You have to use upload and download commands. I would like someone to test it, provide feedback on its functionality, and offer advice on code optimization, etc., because after a while, you start writing clumsy code.
