High-speed counter instructions
28.3 High-speed counter: writing and reading the elapsed value
The elapsed value is stored as a double word in the special data registers. Access the special data
registers using the system variable sys_diHscChannelxElapsedValue (where x=channel number).
System variables for memory areas used:
 FP-Sigma
 FP-X, Transistor types
 FP-X, Relay types
FP0R

 FP0, FP-e
The first example shows how to write an initial value (elapsed value) into the high-speed counter.
Example
The second example shows how to read an elapsed value and copy it to a variable.
