SICAM RTUs, SICAM MIC System Description
85
MC6-054-2.00, Edition 07.2014
DTR
Data Terminal Ready; control line of an RS-232 interface
E
EM II
Confiugration tool of SICAM TOOLBOX II (Engineering Manager II)
Ethernet
Wired local network according to IEEE 802.3
External error
Error that is detected through monitoring the information from sensors and actuators.
Can concern the peripheral element, the wiring, and sensors or actuators, insofar as the source of error
can not be unequivocally localized to the peripheral element; otherwise it would be an internal error.
Externally managed parameter
Parameter that is required on a module (e.g. supplementary module), however, is managed and stored on
the higher-level module
F
FAT
File system on storage media (File Allocation Table); FAT16 up to 2 GB, FAT32 as of 32 GB capacity
Fieldbus interface processor
The fieldbus interface processor serves for the serial connection of SICAM RTUs systems to a Profibus
(Profibus Master); Profibus Slaves are connected acc. to EN 50170-2
FIP
Fieldbus interface processor
Firewall
Blockage of a local network or computer against not allowed access from a supraregional network. Func-
tion for the filtering of data from the internet for the protection against invaders and malicious software.
Firmware
Program that is not changeable by the user, that adds a predefined and parameter-settable functionality to
the hardware
FPU
Floating Point Unit
FUD
Function diagram
Function diagram
Graphical program for open-/closed-loop control functions according IEC 61131-3
FW
Firmware
G
Global parameter
Parameter that is managed and stored on the system element (central system function) but used also on
other system elements of the automation unit
