Note: You can listen to our companion podcast about the 1769-AENTR HERE.
On the front of the unit you can see the reason for the trailing “R” in the part number: dual Ethernet/IP ports. These ports make up a two port Device Level Ring (DLR) switch sharing a single IP address. Also on the front of the unit you'll notice three rotary switches for setting the IP address manually, similar to other A-B Ethernet devices.
According to Dexter, the unit supports all A-B 1769 I/O modules. He also mentioned that Rockwell has also successfully tested several encompass partner 1769 products as well.
Unlike the unfortunate launch of the 1747-AENTR, this unit is being launched with support for the largest 1769 I/O systems: thirty I/O modules across three I/O banks. The unit also comes with an Add-On profile with support for version 20 and 21 of RSLogix 5000.
One important note that came out of our meeting is that the 1769-AENTR does not support rack optimized I/O. This seems to imply that each module will require it's own connection. This is not an issue for the connection rich 5370 multi-core CompactLogix processors (L1xER, L2xER, L3xER.) But, owners of the older connection limited processors (L23E, L32E, L35E) need to take note: with their limited connection count you could easily run out of connections with even a medium sized 1769-AENTR system.
The 1769-AENTR is expected to ship this January (2014) and come at a list price of $980. While more expensive that a similar Point I/O adaptor (the 1734-AENTR) it is less than the aforementioned 1747-AENTR, and substantially less than purchasing a 1769 Ethernet/IP Processor.
Well that's it for my impressions of the 1769-AENTR. at Automation Fair 2013. Check back in he coming days for more impressions of products from this years show.
