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 Management 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 structure of the node and creates a process image from this with all inputs and outputs. 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® IF (Item-No.: 759-340/000-002) includes ready made, freely combinable applications such as stairwell light, touch dimmers and sunblind controls for the fieldbus coupler 750-319. The abbreviation IF stands for "Installation Functions".
The LNS-based plug-in TOPLON® PRIO (Item-No.: 759-340/000-002) is used 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® PRIO.
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".
