5.2 PRODUCT SETUP
i) TFTP PROTOCOL

PATH: SETTINGS PRODUCT SETUP
 TFTP PROTOCOL

The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the L60 over a network. The L60 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file
obtained from the L60 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.
NOTE
j) IEC 60870-5-104 PROTOCOL

PATH: SETTINGS PRODUCT SETUP
 IEC 60870-5-104
 PROTOCOL
5
The L60 supports the IEC 60870-5-104 protocol. The L60 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 L60 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the L60 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.
