After you confirm the parameters with the ok button, the settings are not enabled , only after the CPU
restart, the settings will be enabled? So when you leave the settings the LCD will show you:
You need select “Yes” and press ok, the the CPU will restart, now the new settings will be available.
6.4 How to create the communication between the CPU and PC through Ethernet?
To communicate with the CPU, you can use the TCP/IP protocol. The CPU can work as TCP server and TCP
client at the same time, and also it can work as UDP server or UDP Client as well.
Notes:
1. The Ethernet can work under TCP and UDP mode, you can create the connection between our Ethernet
CPUs, and also you can use our Ethernet CPU to create the connection with other factory Ethernet device
based on TCP or UDP.
2. The communication protocol through Ethernet is MODBUS TCP or MODBUS RTU of our PLC, so if you
want to communicate with other factory device through Ethernet, you need make sure the device also
supports MODBUS TCP. Or MODBUS RTU.
3. Our Ethernet PLC(built-in webserver version) can work either as master or slave.
6.4.1 CPU works as TCP server
The maximum TCP connection is 8, so one CPU allow maximum 8 TCP clients to connect with the CPU at
the same time. And each TCP connection is totally separately.
