Get Poll Connection Input & Output Size and Set the Connection Attributes

Primary Software: Driver Software>>NI-DNET
Primary Software Version: 1.5
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: Industrial Communications>>DeviceNet>>PCI-CAN (DNET), Industrial Communications>>DeviceNet>>PCMCIA-CAN (DNET), Industrial Communications>>DeviceNet>>PXI-8461 (DNET), Industrial Communications>>DeviceNet>>NI DeviceNet Interfaces

Problem:
My DeviceNet slave device supports Poll connection. I want to get the slave device input/output size by programming as Configurator (SimpleWho in the older NI-DNET version) does. What's more, I want to set the related producer/consumer path.

Solution:
You can get the slave device's I/O connection information in NI-DNET Configurator (SimpleWho in the older NI-DNET version). If you want to do the same job by programming, the procedure is:

1. Open the I/O connection by explicit messaging
2. Get the connection attributes, like input/output size
3. Set the connection attributes, like producer/consumer path
4. Release the connection

The attachment shows how to get and set the connection related attributes in LabVIEW.
