11-30Communicating with Devices on an Ethernet Network

Keep in mind these considerations:

•RSLogix programming software on ControlNet and DH+ links cannot see the controllers on an Ethernet link.

•The RSLinx DDE server on a ControlNet link cannot poll data from the controllers on an Ethernet link.

•The RSLinx DDE server on a ControlNet link cannot accept unsolicited data from controllers on an Ethernet link.

•Applications that register themselves as nodes on the RSLinx “Virtual Link” in workstations on ControlNet cannot accept unsolicited packets from controllers on Ethernet.

•Applications that register themselves as nodes on the RSLinx “Virtual Link” in workstations on an Ethernet link cannot accept unsolicited packets from the controllers on an Ethernet link.
