Rio
I agree that it may be better to go with ethernet. Given my issues with RIO, I may not have a choice.
Perhaps someone could help me understand how RIO is configured for a PanelView+.
In RSView Studio, under the RSLinx Enterprise Communications Setup dialog, I add the remote I/O driver. I set this driver for DHRIO since I using a Controllogix PLC. I then configure under the RIOdata, the racks. I set up a rack as Rack 2. I will not set up any block transfers or alias. Do I need to only for dicrete data? I save the config, make a runtime file, and download to the panel.
In the panel under the configuration mode, I load the application. Under applications settings, I go to device shorcuts, select my shortcut, and observe that under RIO is RIOdata, 1. Should this not be RIOdata 2 since I set the rack to 2? It is also the same in the RSLinx Enterprise configuration under terminal settings?
It seems that whatever I set the rack number to in RSView Studio, the RIOdata is always 1. Am I missing something fundamental to configuring this device?
