Chapter 8 Hardware Configuration
8.1.3.9 Ethernet – Advance: Socket
In the Socket table, you can set COM port parameters for data transmission through Ethernet; however, you
need to use this function along with specific API instructions. For more details, refer to the AH500
Programming Manual. The AH500 CPU PLC supports data transmissions between the CPU module and other
CPU module or device through sockets and the communication protocols including TCP and UDP are
supported; four groups of connections can be set respectively for each protocol.
The parameters in the TCP Socket Setting are the same as the parameters in the UDP Socket Setting
except that there is no Keep Alive Timer parameter in the UDP Socket Setting. The parameters in the TCP
and UDP Socket Setting are described below.
