Machine concept The InterBus system is designed as a data ring with a central master/slave access
procedure. It is structured as a widely distributed shift register. Each machine,
with its registers of different lengths, forms part of this shift register ring
through which the data is shifted in series, starting with the master.
Using a ring structure allows data to be sent and received simultaneously. The
data travels through the ring in both directions via a cable.
Each participant in the InterBus system has an ID register (identification regis-
ter). This register contains information about the module type, number of input
and output registers, as well as fault and other statuses.
The InterBus system basically recognises two operating modes:

WARNING!
All activities described in these operating instructions must only be carried
out by trained and qualified personnel.
All functions described in these operating instructions must only be used by
trained and qualified personnel.
Do not carry out any of the work or use any of the functions described until
you have fully read and understood the following documents:
these operating instructions
all the operating instructions for the system components, especially the
safety rules
The ID cycle, for initialisation of the InterBus system and on demand.
In the ID cycle, the interface module in each machine on the bus system
reads the ID register and uses it to create the process image.
The data cycle (the actual work cycle) that handles the data transmission.
In the data cycle, the input data from each machine is transmitted from the
registers to the interface module, and output data is transferred from the in-
terface module to the machines.
