System Networking
Bus Expansion - Standardized performance
With the bus expansion modules from Bachmann electronic for the CPU station, additional backplanes with I/O modules can be added. A configuration is not required to do this; at system start all stations and modules will be automatically detected and initialized. All I/O modules can be reached transparently; the physical structure of the control system does not need to be considered.
Organization of the controller in multiple stations permits both spatial adaptation to the switch cabinet, as well as wide-area distribution of I/O modules for extended machines and plants. There is no restriction for the user in terms of performance and convenience. The interconnected backplanes behave as if they were connected on a single, large backplane.
FASTBUS - Extensive networking possibilities
FO-based FASTBUS solutions provide a simple and reliable way to perform a wide range of decentralization tasks. FASTBUS permits a mixed topology of star and linear networking. In order to design distributed stations even more compact, FASTBUS slaves with integrated power supplies are available. These stations are capable of supplying the I/O modules on the SubDevices.
Between the individual stations distances of up to 2000 m can be bridged with no problems, in this regard the galvanic isolation is ensured by the fiber optic connection. Use of the FASTBUS does not require a configuration or other special handling in the software, but rather functions in accordance with the »plug and play« principle.
