What is the 1734-ADN(X) Adapter? 2-7
• Collects I/O data from the Subnet and sends it to devices on the
DeviceNet network (e.g., scanners or controllers)
• Supplies power to the backplane I/O modules (See Appendix A
for power supply rules regarding I/O modules power
requirements.)
Data Collection
The adapter collects I/O data from up to 63 modules via the Subnet.
The I/O modules appear on the primary DeviceNet network as a
single node, though, and require only one DeviceNet node address.
Module Power
The adapter supplies 5V logic power to POINT I/O modules by
converting 24V dc field power to PointBus 5V power.
You can connect up to 63 I/O modules to each adapter, and you can
power to the backplane I/O modules from the adapter (with a
maximum of 10A of field power). You may use the integrated, isolated
24V dc expansion power unit (1734-EP24DC) to power additional I/O
modules, as shown below.
IMPORTANT
If Automatic Device Replacement (ADR) is enabled
on the adapter, you can only connect up to 62
modules via the Subnet.
For more information on ADR, see page 2-15.
