8. Background knowledge
8.1 What is a BiDiB-Unique-ID?
For working with the BiDiBus all BiDiB modules must have an Unique-ID which can be
found as a label on the casing of the ReadyBoost.
HW-Nr.: 300953YYMMDD117XXXXX
ReadyBoost
BiDiB-Unique-ID:
VFBP7500XXXX
Memorisable names can be given to each module with a host program (=computer
railroad controlling program). The Unique-ID is the link between the given name on
the computer and the module.
8.2 What is needed for bus termination?
The BiDiBus is a RS485 two wire connection which has been especially developed for
high speed data transfer over long distances. This type of connection is used in an
increasing number of industrial installations. Due to the properties high data rates can
be achieved over a length of up to 200 m.
Master
To guarantee an error free communication at this high data rates it is necessary to
terminate the BiDiBus to avoid reflexions.
The terminating resistor of 120 Ohms is part of every BiDiB module and is activated by
fitting the corresponding jumper.
