Sample Programming
This example reads the task period of the current task when this program is first executed after opera-
tion starts. Then the task period that was read is converted from TIME data to LREAL data in millisec-
onds. This sample programming can be used, for example, to calculate the axis target position for each
task period.
The following procedure is used to convert TIME data to LREAL data in milliseconds.
1
The GetMyTaskInterval instruction is used to read the task period as TIME data.
2
The TimeToNanoSec instruction is used to convert TIME data to LINT data in nanoseconds.
3
The LINT_TO_LREAL instruction is used to convert LINT data in nanoseconds to LREAL data
in nanoseconds.
4
The DIV instruction is used to divide the result of step 3 by 1,000,000 to convert to milliseconds.
