The power of the module is cycled by removing bus
connector from channel A.
CONNECTION SCHEMES
Figure 2 - Node B
Left connector represents
the end of network B that is
terminated at right connector.
Figure 3 - Node A
Spanner is located at the end of
the network A. Left connector is
the end of the main network trunk.
Right connector holds terminating
resistor that terminates network A.
Figure 4 - Node A
Spanner is located in the middle
of the network A. Trunk is
passed through the spanner. If
any connector is disconnected,
the rest of the network stays
without power. Connection
represents zero drop length.
Figure 5 – Node A
Repeater is located in the middle
of the network A. Network tee is
used for connecting spanner to
the trunk. If tee is disconnected
from the spanner, the rest of
the network does not loose
power. Connection represents
zero drop length.
Option: Use
the same Tee and drop cable to
connect Spanner that is located
up to 20 ft away from trunk.
CONNECTING SPANNER TO DEVICENET
1. Set Node A address using address A rotary switches,
2. Set Node B address using address B rotary switches,
3. Set I/O data size using Transfer Size switch,
4. Connect module to networks A and B.
5. Start RSNetWorX. Initial, blank program window
pops-up. Press to go on-line.
6. Use RSLinx –Lite (Professional) to configure an
interface to DeviceNet. Interface 1770_KFD will be
used as an example in this document. Press OK.
Go online and browse the network. Node 4
and 11 represent node A and B respectively.
