Suite™ IDE software and online help system.
2.1 PROFIBUS
Coupler (AKT-PRB-000-000)
The Bus Coupler connects the PROFIBUS system to the electronic terminal blocks, which can be
extended in modular fashion. One unit consists of the Bus Coupler, any number of up to 64
terminals and one end terminal. Up to 64 digital input/output terminals can be connected.
The Bus Coupler recognizes the connected terminals and automatically generates the affiliations
of the inputs/outputs to the bytes of the process image. The first input/output signal is inserted in
the first bit of one byte (LSB), beginning from the left. The Bus Coupler inserts further signals in
this byte. Inputs and outputs are clearly separated. The Bus Coupler automatically begins a
further byte if the number of inputs or outputs exceeds 8 bits.
The Bus Coupler supports the operation of all Bus Terminals. As far as the user is concerned,
handling of the analog inputs/outputs is not different to other series. The information is available
in the process image of the controller for processing in the form of a byte array.
The Bus Terminals can be controlled by the control system. Via function blocks (FBs), the
programmable logic controller (PLC) or the handles configuration of the complete periphery
during the start up phase. If required, the controller can upload the de-centrally created
configuration data in order to centrally manage and store this data. Therefore, new adjustments
are not necessary in the event of replacement of a Bus Terminal. The controller automatically
sets the required setting on power up.
