Hello, I've recently been trying to use Network Rails Open Data TD feed and, I'm confused about how to interpret which signals are being changed from the address field? Please help. I am looking in the BP area, I have the SOP table for the area but don't know how to see what signal is changing its status. Any help is appreciated

If you've got the SOP all the hard work has been done, you just need to decode the bytes supplied into eight bits. Watch out for the booby trap that the SOP is in decimal but the TD feed address and data fields are in hex.

I had a look at the openraildata wiki but i couldn't make much sense of it but the way you've explained it makes more sense now
