Selective dataflow routing
Routing of individual process information items. In simple applications the messages are distributed by
means of an entry in the topology. For more complex applications, the messages can be distributed selec-
tively by means of dataflow filters: for each communication interface, band-pass filters or blocking filters
can be set. Also wildcards can be used for all address attributes of the message, to direct the dataflow
very specific.
SI
Single-point information
Serial interface module
Hardware of a protocol element that can be installed on a basic system element
Serial interface processor
The serial interface processor serves for the serial connection of SICAM RTUs systems via a transmission
facility or via a direct connection
SIM
Serial interface module
SIP
Serial interface processor
Single command
A command used to cause a change of state of operational equipment in one direction
Single-point information
Monitored information represented by only one bit characterizing two determined states of operational
equipment
SMS
Short Message Service, transmission of up to 160 characters
SNMP
Simple Network Management Protocol
SNMP is a network protocol to monitor and control network components (e.g. router, switches, server, printer)
from a central station.
SNTP
Simple Network Time Protocol
Spontaneous datapoint
Binary information that is transmitted upon change spontaneously in a message. It is always transmitted
individually, and usually has a time tag in order to be able to establish a chronologically consistent interre-
lationship afterwards.
With the current, voltage and counting pulse acquisition a spontaneous transmission of the information
takes place threshold value controlled (exception:class 2 data with dial-up traffic).
Spontaneous information object
A spontaneous information object that is transmitted upon change spontaneously in a message, and is
used for the exchange of a process signal or a derived information (including status) between the periph-
eral element and the particular automation unit, another automation unit or a control system.
A spontaneous information object is always transmitted individually and normally has a time stamp, in or-
der to be able to establish a chronologically consistent interrelationship later.
