FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What are the selectable DeviceNet transmission rates (baud rates) supported by this daughtercard?

A: The supported selectable transmission rates are 125 Kilobaud, 250 Kilobaud, and 500 Kilobaud.

Wiring & Installation:

Q: What is the valid range for setting the DeviceNet node address using the hardware switches?

A: Valid node addresses are 0 to 63, which must be unique across the DeviceNet network segment.

Troubleshooting & Compatibility:

Q: What action should be taken if the module status (MS) indicator is flashing red-green?

A: Flashing red-green indicates the device is in self-test; if this persists, the card may need replacement.

Replacement & Upgrades:

Q: Which software version is required to configure the 1788-DNBO module in a logix system?

A: RSLogix 5000 V12 or a later version is required for configuration, often paired with firmware 2.002.
