2.2 The PROFIBUS-Compatible Network
SINEC L2/L2FO
Within the open, heterogeneous SINEC communications system, SINEC
L2/L2FO is the network for the cell and field area, intended particularly for
industrial environments.
The SINEC L2 network complies with the German process and field bus
standard PROFIBUS DIN 19245.
SINEC L2
is the
electrical
network based on a shielded, twisted pair.
The optical network
SINEC L2FO
(FO = fiber-optic) is the
optical version
of SINEC L2, i.e. the data transmission between two components (DTE =
data terminal equipment) is on fiber-optic cables.
SINEC L2/L2FO has the following characteristics:
➣ Low installation costs
➣ High flexibility in its communications options, i.e. open communication
by using standards
➣ A variety of possible network topologies using repeaters
The SINEC L2/L2FO bus system can be used in a variety of areas of
application, e.g.
➣ Process engineering
➣ Production engineering
➣ Mechanical engineering
➣ Power engineering
➣ Building automation
