Frequently asked questions

You can set the node address using the DeviceNet Manager Software (or similar configuration software tool) and a 1770-KFD RS-232 module (or similar interface). The steps for setting the node address are explained in detail on page 3 of the document.

Yes, you can mount the module in any orientation. However, the preferred mounting position is with the microconnectors pointing down. This helps prevent water or other liquids from building up under the module during washdowns.

The module uses quick disconnect, screw-on style connectors for I/O input wiring, I/O output wiring, power wiring for I/O outputs, and the DeviceNet connector. The pinout diagrams for these connectors are shown on page 9 of the document.

The default settings are: autobaud enabled, off to on delay and on to off delay set to no delay, fault state set to reset outputs, and idle state set to reset outputs. You can change these settings using the DeviceNet Manager Software.

You can reset faults by cycling power to the module, using the Reset Faulted I/O feature on the parameter screen, using the explicit message program control feature, or by removing and reconnecting the output power connector.
