4.8 Configuration of Inputs and Outputs (Configuration Matrix)
A configuration matrix is used to determine processing of the binary inputs, outputs,
LEDs, and indication buffers.
Configuration is performed with DIGSI
®
4.
The configuration matrix is primarily divided into the following columns:
q
Device functions
q
Information, e.g. indications or command with
G information number, identification of the information,
G
display text, representative brief text of the information on the device display,
G long text, extensive description of the information,
G
type, identification of the information, e.g. CF_D2 double command with feedback
indication;
q
Source, that is, origin of the information with
G binary inputs, for the input of binary information
G
function keys, freely programmable keys on the operating field, e.g. assigned
switching operations, etc. as the origin of the information,
G CFC (programmable logic), user-specific logic outputs as the origin of the informa-
tion;
q
Destination of the information, with
G
binary outputs for the output of signals,
G LED, display of information on the device front, e.g. messages,
G
system interface, transmission of information, e.g. to a substation control system,
G CFC (programmable logic), information as an input to a user-specified logic,
G
buffer, in which the information should be entered,
– event log or
– earth fault message
– trip log,
G
display, information shown in
– control display
– default display
G control menu, primary device can be controlled or tagging can be set.
The user determines the configurations by
G clicking on the appropriate column, or by
G Using the context menu: L (latched), U (unlatched), H (activate high),
L (activate low), (not configured), (configured) etc.
DIGSI
®
4 checks the entry for plausibility and locks the input field if necessary. A
locked input field is shown in gray.
