Trying to understand the basics of the wiring in my machine (SV-2412 with Fanuc Oi-mate_MC control).
Some of the wires from the I/O boards go in a 50-pin cable to a breakout board (terminal block) which then split off and go to relays, etc. Others wires go from the I/O board 50-pin cable straight to connections and skip the breakout board. Why do some wires need to go to a breakout board and others don't and can go straight to a component from the I/O board? It seems like the breakout board just adds another connection that isn't needed since its passive and isn't one of the active types of breakout boards that protects the wiring by transferring the signal across an electronic connection to isolate the signal.
And most (all?) of the wires go to the left side of the panel to a long vertical terminal strip and then across that strip to another wire labeled the same and then to somewhere else. Why is that long terminal strip there? It just seems like it just adds another connection that could fail. Is it mostly so a technician can touch/connect to the wires for diagnostics (it looks like the strip has a place on each connection to put a spade type connector into)? Or is it just so that someone can read the labels on the strip for clarity so that they don't have to try to find each wire somewhere else? IOW it's like a switchboard and the convenience of knowing where all the wires are at is higher priority than the extra connection reliability?
