GE Energy
Flexible Function
Block
This is similar to a Standard FB, except that the function of the
block, the order and definition of the block parameters, and the
time required to execute the block are determined by an applica-
tion-specific algorithm created by a programming tool. Flexible
Function Blocks (FBs) are typically used for control of discrete
processes and for hybrid (batch) processes. A Programmable
Logic Controller (PLC) can be modeled as a Flexible Function
Block device.
FMS Fieldbus
Messaging Service
Frame
A defined area in the Windows dialog that groups related data.
H1 H1 is a term used to describe a fieldbus network operating at
31.25 kbit/second.
H1 Field Device This is a fieldbus device connected directly to an H1 fieldbus.
Typical H1 Field Devices are valves and transmitters.
H1 Repeater This is an active, bus-powered or non-bus-powered device used
to extend the range over which signals can be correctly transmit-
ted and received for a given medium. A maximum of four Repeat-
ers and/or active Couplers can be used between any two devices
on an H1 fieldbus network.
Hazardous Area The area of the plant where explosion hazards can be present,
hazards such as propane gas in a refinery, or dust in a flour mill.
Hexadecimal Notation for numbers to base 16. The number sequence is
0,1...9, a, b, c, d, e, f to represent decimal 0 to 16. Customarily
hexadecimal notation is identified with the preamble 0x.
High Speed Ethernet
(HSE)
This is the Fieldbus Foundation's backbone network running at
100 Mbit/seconds.
Hot swappable The FVP in combination with ValVueFF enables a very brief
Mean Time To Repair by the following process: Upload all config-
uration information from installed positioner to ValVueFF, then
replace the positioner and download the configuration file. Run
STOPS, and autoTUNE, and the repair is complete.
HSE Field Device This is a fieldbus device connected directly to a High Speed
Ethernet (HSE) fieldbus. Typical HSE Field Devices are HSE
Linking Devices, HSE Field Devices running Function Blocks
(FBs), and Host Computers.
HSE Linking Device This is a device used to interconnect H1 fieldbus Segments to
High Speed Ethernet (HSE) to create a larger network.
HSE Switch This is standard Ethernet equipment used to interconnect multiple
High Speed Ethernet (HSE) devices such as HSE Linking
Devices and HSE Field Devices to form a larger HSE network.
