Automation unit
An automation unit is a modular structured device for the acquisition, processing and output of process in-
formation. It communicates in automation networks via a serial or Ethernet protocols with other automa-
tion units or control center systems.
An automation unit consists of at least 1 mounting rack or 1 DIN rail (depending on system), 1 power sup-
ply and 1 basic system element, as well as optional peripheral elements and optional protocol elements.
Automatic dataflow routing
The routing of individual process information items is not necessary. Simply only the direction (monitoring
direction, control direction, both directions) the messages are to be transmitted must be parameterized.
The type identification of each message gives information about to which class a message belongs and
with which methods it is to be distributed.
Messages with process information in monitoring direction are distributed by means of an entry in the to-
pology. Messages with process information in control direction are distributed to their target that is deter-
mined by their CASDU and via interfaces that are defined in the topology. The CASDU is interpreted as
target address.
Ax peripheral bus
Enables the secured (hamming distance 4), serial, system-internal communication between the basic sys-
tem element and the peripheral elements
Ax PE Bus
ž
Ax peripheral bus
B
Basic system element
System element for processing of information according to different criterions (e.g. automation,
telecontrol, etc.) and for the administration of system functions (e.g. parameter, diagnosis, etc).
Binary
Representation of information by means of 2 different states or 2 discreet values (=digital)
Binäry signal
Electrical signal that is used for the transport of a binary process information; as well as the digital signal,
2 different and not coherent ranges of the electrical signals are defined, for each a status/value that the
binary process information can receive. Therefore, in the technical data of digital inputs that are designed
for the acquisition of binary signals, voltage ranges for "logical 0" and "logical 1", the universal designation
for the both states/values.
Binary input
Designation for a module, a submodule, an I/O module etc. for the acquisition of binary signals; task of a
"binary input" is the evaluation of binary signals and therefore the recovery of the binary process infor-
mation
Binary input
Hardware for the acquisition of a binary signal (single-point information, double-point information)
Binary output
Hardware for the output of a binary signal (information or command)
Binary process information
Process information of type
ž
binary, e.g. circuit breaker position ON/OFF
BSE
ž
Basic System Element (master control element, processing and communication element)
C
CAEx plus
Tool for the creation of application programs (Computer Aided Engineering), based on the tool logiCAD ®
from the company logi.cals ®
CASDU
Common Adress of the
ž
ASDU, that part of the ASDU, that is common for all ASDUs of a station
Cause of transmission
Spontaneous transmission, general interrogation data, periodical data, command preparation, command
command activation (acc. to IEC 60870-5-101)
