(2) Features of vision system connection function
This section explains the features of the Cognex vision system connection
function.
(a) Method of connection with vision system
The Motion CPU and vision system are connected with the Motion CPU's
PERIPHERAL IF (Ethernet). A dedicated communication module, etc., is not
needed.
POINT
(1) The Motion CPU and vision system are connected via Ethernet. The response
of vision system dedicated functions may slow down if several devices (MT
Developer2, personal computer for In-Sight
connected via an Ethernet HUB.
(2) When simultaneously controlling two or more vision systems, the execution of
commands to other vision systems may be delayed during the log on process
(MVOPEN) with a specific vision system.
(3) When simultaneously controlling two or more vision systems, if the offline-
online state for a specific vision system is switched from an external source,
the execution of commands to other vision systems may be delayed.
(4) Execution of the vision system dedicated functions may be delayed if the
vision system is in the offline state.
(5) When the vision system is logged onto, communication is established between
the Motion CPU and vision system to check the connection state even if the
vision system dedicated functions are not used.
