24 Introduction to the manual
FbEq16 16-bit fieldbus equivalent: The scaling between the value shown on the
panel and the integer used in communication when a 16-bit value is
selected for transmission to an external system.
FbEq32 32-bit fieldbus equivalent: The scaling between the value shown on the
panel and the integer used in communication when a 32-bit value is
selected for transmission to an external system.
F-Device Device that is able to communicate using PROFIsafe, eg, the FSO
module.
F-Host Programmable logic controller (PLC) that is able to communicate using
PROFIsafe.
F-Input PROFIsafe frame user data from that is sent from the F-Device (FSO) to
the F-Host (PLC).
F-Output PROFIsafe frame user data from that is sent from the F-Host (PLC) to
the F-Device (FSO).
F-Parameters Set of PROFIsafe parameters that all PROFIsafe devices support.
F-Parameters are sent from the F-Host (PLC) to the F-Device (FSO)
when the PROFIsafe connection is created.
FBA Fieldbus adapter parameter (drive parameter group 50)
FB module Fieldbus adapter module (FPNO-21 or FENA-21)
FENA-21 Optional Ethernet adapter module for EtherNet/IP
™, Modbus TCP and
PROFINET IO protocols
FIT Failure in time: 1E-9 hours. Expected failure rate of semiconductors and
other electronic devices. (IEC 61508)
FPNO-21 PROFINET fieldbus adapter module
FSE-31 Pulse encoder interface module which can be used in safety
applications
FSO-12 Safety functions module which does not support the use of encoders
FSO-21 Safety functions module which supports the FSE-31 module and the
use of safety encoders
Functional safety Functional safety is part of the overall safety that depends on a system
or equipment operating correctly in response to its inputs.
Generator mode Drive is taking energy from the controlled application
GND Ground
GSD file General Station Description file that describes the basic capabilities of a
device in a specified form. PROFINET uses GSDML files which are
GSD files written in XML format.
HAT Host acknowledgement time
Hazard Potential source of harm (physical injury, or damage to health or
equipment)
HFT Hardware fault tolerance (IEC 61508)
