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
Example
The first example shows how to write an initial value (elapsed value) into the high-speed counter.
The second example shows how to read an elapsed value and copy it to a variable.
All input and output variables used for programming this function have been declared in the POU
header.
Body
An initial value of 3000 (elapsed value) is written into channel 0 of the high-speed counter.
