Chapter 5 Communication Connections
•
EtherNet/IP Client/Server
•
Modbus TCP Client/Server
•
DHCP Client
•
Sockets Client/Server TCP/UDP
Here are some configuration examples based on the limits described in the table
above:
1.
The maximum number of drives that can be controlled over EtherNet/IP
is 16. This is due to the maximum limit of TCP Client connections is 16,
and the maximum limit of EtherNet/IP Client connections is also 16.
2.
If you have 10 devices controlled over EtherNet/IP, the maximum number
of devices that can be controlled over Serial is six. This is due to the
maximum limit of Client connections is 16.
