5.2 PRODUCT SETUP
The MMXU deadband settings represent the deadband values used to determine when the update the MMXU "mag" and
"cVal" values from the associated "instmag" and "instcVal" values. The "mag" and "cVal" values are used for the IEC 61850
buffered and unbuffered reports. These settings correspond to the associated "db" data items in the CF functional con-
straint of the MMXU logical node, as per the IEC 61850 standard. According to IEC 61850-7-3, the db value "shall repre-
sent the percentage of difference between the maximum and minimum in units of 0.00%". Thus, it is important to know the
maximum value for each MMXU measured quantity, since this represents the 100.00% value for the deadband.
The minimum value for all quantities is 0; the maximum values are as follows:
phase current: 46 × phase CT primary setting
neutral current: 46 × ground CT primary setting
voltage: 275 × VT ratio setting
power (real, reactive, and apparent): 46 × phase CT primary setting × 275 × VT ratio setting
frequency: 90 Hz
power factor: 2
The GGIO2 control configuration settings are used to set the control model for each input. The available choices are "0"
(status only), "1" (direct control), and "2" (SBO with normal security). The GGIO2 control points are used to control the D60
virtual inputs.
Since GSSE/GOOSE messages are multicast ethernet by specification, they will not usually be forwarded by net-
work routers. However, GOOSE messages may be fowarded by routers if the router has been configured for VLAN
functionality.

WEB SERVER
HTTP PROTOCOL
The D60 contains an embedded web server and is capable of transferring web pages to a web browser such as Microsoft
Internet Explorer or Netscape Navigator. This feature is available only if the D60 has the ethernet option installed. The web
pages are organized as a series of menus that can be accessed starting at the D60 "Main Menu". Web pages are available
showing DNP and IEC 60870-5-104 points lists, Modbus registers, Event Records, Fault Reports, etc. The web pages can
be accessed by connecting the UR and a computer to an ethernet network. The Main Menu will be displayed in the web
browser on the computer simply by entering the IP address of the D60 into the "Address" box on the web browser.
i) TFTP PROTOCOL
PATH: SETTINGS PRODUCT SETUP
TFTP PROTOCOL
The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the D60 over a network. The D60 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file
obtained from the D60 contains a list and description of all available files (event records, oscillography, etc.).
