 TFTP PROTOCOL

The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the B30 over a network. The B30 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file
obtained from the B30 contains a list and description of all available files (event records, oscillography, etc.).

The B30 supports the IEC 60870-5-104 protocol. The B30 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 B30 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the B30 at one time.

Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to trigger
