SICAM RTUs, SICAM MIC System Description
MC6-054-2.00, Edition 07.2014
Automatic data flow routing
Selective data flow routing
Datapoint
Analog or binary information (process data point, System data point)
Data stream
Transports a sequence of data-point related information through the telecontrol system from a source to
one or more sinks.
There are spontaneous and periodical data streams. (spontaeous data strems transport information in tel-
egrams)
Datentransporter and system message router
System-internal distribution point for application data and system data messages from and to the single
systemfunctions resp. application; application data is distributed by means of routing, system data by
means of target addressing to the data sinks
DCD
Data Carrier Detect; control line of a RS-232 interface for the evaluation of the receive signal level
DCE
Data Communications Equipment; for example a modem
DDC
Data Distribution Center; Tool for the export, import and/or administration of SICAM TOOLBOX II data
Detailed diagnostic record
Comprises 16 diagnostic bits (of a system diagnostic class) that commonly belong logically together
Detailed diagnostic table
Contains all diagnostic bits recognized by the basic system element and the supplementary system ele-
ments
DI

Binary output
DMS
Digital Multiplex System
DO
Digital output
Double command
A pair of commands each of which is used to cause operational equipment to change to one of two de-
termined states.
Double-point information
Monitored information represented by two bits characterizing two determined states and two states of op-
erational equipment.
DSR
Data Set Ready; control line of an RS-232 interface
