How can the PDI channel be read/written with the CXA_S20 library when the subindex is limited to bytes while some of the supported IO has subindexes of word length?
For example, the S20-SGI module has sub-index 0x0298 but the input to read/write through the CXA_s20 IH_S20ECATPDIRead/Write only supports byte lengths (limited to 0x00FF).

The Subindex is just one Byte at the S20-EC-BK for the PDI Tunnel and it define the e.g. channel.
The mentioned parameter 0x0298 is the index.

This was the issue. I guess I switched the 2 (index and sub-index) when I was reading it. Thanks!
