IP communication test
When the IP packet transfer function is used, whether no error occurs in the communication route within CC-Link IE
Field Network is checked. The following can be checked using the IP communication test:
• Cables are properly connected on the communication route.
• Parameters related to the IP packet transfer function, such as an IP address and routing parameters, are
correctly set on the communication route.
• All the CPU modules and master/local modules on the communication route support the IP packet transfer
function.
The following system configuration is used to explain the procedure of the IP communication test.
The IP communication test allows the communication paths in the dotted line above to be checked.
1.
Set parameters for the CPU module and master/
local module. (
2.
Write the set parameters to the CPU module using
GX Works2.
