How do I set up a PCI-DNET card as master with A-B DNI as slave?

[Zeddicus]

I'm trying to communicate with an Allen Bradley PLC through DeviceNet.  I have a NI PCI-DNet card in my computer, and an Allen-Bradley 1761-NET-DNI interface between my PLC and the DeviceNet network.  Does anyone know how to set up my National Instruments card as the Master of my PLC/DNI combination?  Thanks in advance for the help.

Hi Mark:

The PCI-DNET card should set itself up as the master by default.  As a matter of fact it should take more work to get it be the slave than to get it to be the master.  Is this not what you are experiencing?  Is there some sort of Allen-Bradley software that you have installed that is not allowing the NI board to be the master?

The DNET Manual states on page 4-8 that NI-DNET assumes that it is the only master in your DeviceNet system.
