PRODUCT SETUP
TFTP PROTOCOL
The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the L30 over a network. The L30 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file
obtained from the L30 contains a list and description of all available files (event records, oscillography, etc.).
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.

PROTOCOL

The L30 supports the IEC 60870-5-104 protocol. The L30 can be used as an IEC 60870-5-104 slave device connected to a
maximum of two masters (usually either an RTU or a SCADA master station). Since the L30 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the L30 at one time.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.
