To view or edit the link active schedule, double-click the Schedule icon in
the configuration tree. The schedule window appears in the middle frame.
In the schedule window, a key to the scheduled objects appears on the left.
The timing diagram on the right displays the execution times of the function
blocks, and when data is transmitted on the bus. The blue bars on the screen
correspond to the function block execution times and the red bars
correspond to the data transmission times, which consist of LAS
notification time and transmission time.
Tip With only one device, you will not see data transmission since there are no parameters
that need to be transmitted to other devices. Also, for some fast devices (such as the
FP-3000), the blue block execution bars are so short that they are entirely hidden behind
the block icons themselves.
Note An optimized schedule can show that the transmission time overlaps the end of
function block execution. This is because the transmission time includes the time that the
LAS uses to tell the device to publish the data.
