(2) Timing chart
The following shows a timing chart of the positioning function by the operation start-up signal. The
positioning operation can be started by enabling the operation start-up signal and turning on ST
(operation start-up).
Note that the positioning operation by the operation start-up signal cannot be started even though the
operation start-up signal is enabled during positioning operation with the network communication. The
positioning operation with the network communication cannot be started even though the operation
start-up signal is disabled and the start-up signal is input with the network communication during
positioning operation by the operation start-up signal.
Switching of the network communication and the operation start-up signal can be executed only when a
positioning is completed. Completion of a positioning can be checked with Target reached (Statusword
bit 10).
