Fieldbus coupler/controller
Fieldbus coupler 750-319
3.1.1 Description
This buscoupler allows connection of the WAGO-I/O-SYSTEM 750 as a
slave via FTT (Free Topology Transceiver) to the LON fieldbus.
All input signals of the sensors are consolidated in the coupler/controller and
transfered via fieldbus to the superior control system (PC with Network Man-
agement Tool Software). In the superior control system the linkage of the
process data can take place. Afterwards the resulted data will be exported via
fieldbus and network node to the actuators.
The data is transmitted with network variables.
In the initialization phase the fieldbus controller determines the physical struc-
ture of the node and creates a process image from this with all inputs and out-
puts. This could involve a mixed arrangement of analog (word by word data
exchange) and digital (byte by byte data exchange) modules.
The local process image is subdivided into an input and output data area.
The data of the analog modules are mapped into the PDOs according to the
order of their position downstream of the bus coupler. The bits of the digital
modules are compiled to form bytes and also mapped into PDOs. Should the
number of digital I/Os exceed 8 bits, the coupler automatically starts another
byte.
3.1.2 Software for the coupler
The LNS-based plug-in TOPLON
ready made, freely combinable applications such as stairwell light, touch dim-
mers and sunblind controls for the fieldbus coupler 750-319. The abbreviation
IF stands for "Installation Functions".
The LNS-based plug-in TOPLON
to connect the fieldbus coupler directly to the LON network.
The fieldbus coupler 750-319 is provided with the RIO-function which is the
remote operating mode of TOPLON
With the RIO-function the I/O data can be directly assigned from the fieldbus
node to the network variables.
The abbreviation RIO stands for "Remote I/O".
