2. Create a New Network
1.
After the EDS file has been loaded in RSNetWorx, you can start estab-
lishing your network.
For this purpose, click in the tree structure located in the left-hand screen
window on the "Communication Adapter" folder.
A list of various sub-folders appears.
2.
From the list of sub-folders, select the corresponding scanner available in
your network (for the present example, select "1747 SDN Scanner Mod-
ule").
3.
Take over the selected scanner into the right-hand graphics window with a
double-click or drag&drop.
The selected scanner is displayed in the right-hand screen window as a
symbol.
4.
Now select the DeviceNet Controller 806 in the tree structure in the
"Communication Adapter" folder.
5.
Also take this over into the right-hand graphic window with a double-click
or drag&drop.
The Controller is added to the right-hand screen window as a second sym-
bol.
3. RX/TX Calculation for the Mapping
The correct setting of the TX/RX configuration is a prerequisite for the perfect
running of the DeviceNet network. For this purpose, the TX/RX configuration
must coincide with the node configuration.
For the entry into the RX and TX fields in RSNetworx, all input bit/bytes
count as a whole, as well as all output bits/bytes.
Here, individual bits are always grouped to form full bytes.
From the fieldbus master standpoint, the example node has the following data
configuration:
