BEI Sensors MHK5 Absolute Hollow Shaft Encoder - Manual (Page 46)

GSD file
File that contains slave-specific characteristics. The GSD file is supplied by the
manufacturer of the profibus slave. The GSD format is standardized (defined in
GSD specifications), so configuration tools of various manufacturers can use
the GSD files.
Master
“Active” device in the network that can send data without request. Controls the
data interchange.
Octet Data unit of 8 bits = 1 byte
Profibus
Process Fieldbus, European fieldbus standard, which is defined in the
PROFIBUS Standard (EN 50170). This specifies functional, electrical and
mechanical characteristics for a bit-serial fieldbus system.
Slave
Bus node, that only sends data on request of the master. Absolute rotary
encoders are always slaves.
Terminating resistor
Resistor that terminates the bus cable; terminating resistors are always
required at the end of a cable or segment.
Type file Similar to GSD file, is used with older configuration software tools.
Word Expression used for a data unit of two bytes.
