5-3 HSC Range
HSC’s count range is: K-2,147,483,648 ~ K+2,147,483,647. If the count value overflows this
range, then overflow or underflow appears;
Overflow means the count value jumps from K+2,147,483,647 to K-2,147,483,648, then
continue counting; underflow means the count value jumps from -2,147,483,648 to
+2,147,483,647 then continue counting.
5-4 HSC Input Wiring
For the counter’s pulse input wiring, things differ with different PLC model and counter
model; several typical input wiring diagrams are shown below: (take XD3-60 HSC0 as the
example):
