2.3.3Ethernet support
The Ethernet module (EN311) is available for the T3H. By using the EN311, the T3H can be connected to Ethernet network.
Using the Ethernet module, the T3H supports the following communication functions.
•Computer link function:
Host computer on the Ethernet can perform data read/write, T3H status read, program
•
By using SEND and RECV instructions, any register data of a T3H can be sent to other T3H, and any register data of other T3H can be read into a T3H, via Ethernet.
•Socket service:
Communication between a computer and a T3H user program is available by using SEND and RECV instructions. Maximum 8 ports of socket are available. The protocol can be selected either TCP/IP or UDP/IP for each port.
Up to four EN311’s can be installed on a T3H.
To activate the EN311, SEND instruction is required to set parameters (IP address, UDP port number) and to send commands (communication start, etc.)
