vision system
The following three communication methods can be used simultaneously with Ethernet.
(Note-1)
2) TCP/IP protocol
(Note-1): The simultaneous communication cannot be used depending on the vision system's model.
Refer to the manual or help sections provided by Cognex to confirm the specifications of vision
system.
1) Telnet
The vision system is controlled from the Motion CPU using the native
mode. The vision system dedicated functions control the vision system
using Telnet.
2) TCP/IP protocol
By using TCP/IP as the vision system communication protocol and
setting the output string, the image data are sent in a batch to the Motion
CPU immediately after the job is finished with the vision system.
High-speed data transfer is possible compared to the other
communication methods.
3) MC protocol
By setting the vision system, data can be easily exchanged between the
vision system and Motion CPU device.
Refer to the manual, etc. provided by Cognex for details on using MC
protocol.
The Motion CPU parameters (built-in Ethernet port open setting) must
also be set.
(b) Vision system parameter
Parameters required for Ethernet communication and job execution must be
set beforehand with MT Developer2.
The vision system can be controlled just by writing only the vision system
dedicated functions in the Motion SFC program.
