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
q
information number, identification of the information,
q
display text, representative brief text of the information on the device display,
q
long text, extensive description of the information,
q
type, identification of the information, e.g. CF_D2 double command with 2 output
contacts and feedback indication;
q
Source, that is, origin of the information with
q
binary inputs
q
function keys F, freely programmable keys on the operating field, e.g. assigned
switching operations, etc. as the origin of the information,
q
CFC C (programmable logic), user-specific logic outputs as the origin of the infor-
mation;
q
Destination of the information, with
q
binary outputs for the output of signals,
q
LED, display of information on the device front, e.g. messages,
q
system interface S, transmission of information, e.g. to a substation control system,
q
CFC C (programmable logic), information as an input to a user-specified logic,
q
buffer, in which the information should be entered,
– operation annunciation buffer or
– fault annunciation buffer,
q
control menu CR, primary device can be controlled or tagging can be set.
The user determines the configurations by
q
clicking on the appropriate column, or by
q
Using the context menu: L (latched), U (unlatched), H (activate high),
L (activate low), (configured), (not configured), etc.
DIGSI
®
4 checks the entry for plausibility and locks the input field if necessary.
A locked input field is shown in gray.
