Earlier this week in this article we discussed the new products detailed in Rockwell's updated visualization guide.
In addition to new products, we also noticed the part numbers for PanelView Plus models supporting Remote I/O and DeviceNet were missing.
Not sure if this was an indication of obsolescence, we pointed our web browser to www.ab.com/silver and searched on 2711P.
The results were clear – all DeviceNet and Remote I/O models of the PanelView Plus had indeed been re-classified as “End of Life,” with a discontinued date of January 31st, 2016.
Is this a bad thing?
While it's true using HMI's on I/O networks never provided the flexibility or ease of use that peer to peer networks afforded, losing these options do make migrating HMI's from these legacy networks a little more challenging.
That's not to say I would recommend replacing a legacy DeviceNet connected HMI with another DeviceNet HMI.
But I do know first hand the challenges of replacing Remote I/O HMI's with something different.
In many cases there's just no other network drop near where the old RIO HMI is located.
And most PanelView's on RIO utilize both Digital I/O as well as Block Transferred Data, which means migrating those applications to a peer to peer network (DH+, Ethernet, etc) typically requires editing the PLC's program.
What do you think? Is the timing of this obsolesce on-track or pre-mature?

- Shawn do you have any training for DeviceNet?Good morning ,
I don't have any DeviceNet training currently - it's something I want to do but don't have scheduled.
I hope to do a video on DeviceNet for The Automation Show later this year, and have been wiring up the demo wall in Studio B in preparation.
Instructor at www.TheAutomationSchool.comThanks Shawn! I'm currently trying to convert a Micro-Logic 1500 PLC to a Compact-Logic PLC; due to budget issues and downtime I have to keep the Device-Net in place...
So I'm trying to get up to speed on the Device-Net part of the project...
Yeah, with those jobs the biggest thing to look for is the existing DNET mapping in the 1500.
Also, making sure the data ends up in the same place in the new program since the 1500 didn't use DINTs like the CPX.
Here's to a smooth conversion!
