F
FHSS
Generally: The frequency hopping process known as "Frequency Hopping
Spread Spectrum" (FHSS) involves the division of a frequency range into
sub-ranges, between which the data transmission then alternates. This im-
proves co-existence with other networks and provides additional tapping
protection and strength against narrow band disturbing influences.

channels. Each time, after transmission of a packet, the current sub-channel
is changed. This may occur up to 1600 times per second.
Firmware
For this module: Software of the microcontroller used. The following ver-
sions can be queried separately: host controller and baseband controller
Flag
An indicator for identifying certain conditions. A flag is represented by one
bit. A certain status is represented by a certain bit value.
Function block
Function blocks are used for IEC-61131 programming and stored in libraries
for repeat use. A function block is a structured module, which has a name
and contains input and output variables, as well as local variables.
G
Gateway
Device for connecting two different networks, performs the translation be-
tween differing protocols.
