Machine I/O
Bu içerik henüz dilinizde mevcut değil.
MACHINE I/O is the screen to open when the machine refuses something and nothing on the
program explains it: a cycle that will not start, a tool changer that stops half way, a
probe that never arms.
Two lamps, not one
Section titled “Two lamps, not one”Every point shows both:
| Lamp | Is |
|---|---|
| PHY | the terminal itself, what the wire is doing |
| LOGIC | what the machine logic makes of it |
That pairing is the whole point of the screen. A door switch that reads PHY on and
LOGIC off is mapped or inverted wrongly; one that reads off on both is a switch, a wire
or a fuse. Nothing else on the machine separates those two faults.
A normally-closed input reads on when nothing is wrong. E-stop and reset are wired that way: their lamps go out when the button is pressed. An operator expecting the opposite reads a healthy machine as a broken one.
It only reads
Section titled “It only reads”Nothing on this screen switches anything. Reading a point down the phone to whoever is fixing the machine is what it is for.
Where to go next
Section titled “Where to go next”- PLC Signals in Macros: putting these same signals in front of a part program.
