Chapter 5 Communication Connections
•
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.
3. The total number of UDP sockets plus TCP Client/Server sockets has a
maximum limit of eight.
Modbus RTU
Modbus is a half-duplex, master-slave communications protocol. The Modbus
network master reads and writes bits and registers. Modbus protocol allows a
single master to communicate with a maximum of 247 slave devices. Micro800
controllers support Modbus RTU Master and Modbus RTU Slave protocol. For
more information on configuring your Micro800 controller for Modbus
protocol, see the Connected Components Workbench Online Help. For more
information about the Modbus protocol, see Modbus Protocol Specifications

IMPORTANT
If all client/server connections are fully loaded, performance may be
affected, such as data loss and intermittent delays during communication.
