1761-NET-DNI Replacement?

Hello Friends

I need to communicate a 5/03 PLC with a Micrologix 1400, to send and receive some bits and integers between both PLCs.

Int the 5/03 the channel 0 is used by a Panelview.

The 5/03 PLC has a 1747-SDN Devicenet scanner, so I have thought in a 1761-NET-DNI connected to the micrologix 1400.

But, 1761-NET-DNI have been discontinued from 2013. I have asked to AB for a replacement but i have not received response.

Do you know a replacement for this interface?

o maybe another way to communicate 5/03 with ML1400?


Thanks in advance.

Do you have to use DeviceNet? You can still get the 1761-NET-ENI until Jan 2017 so you could use ethernet between the SLC and the 1400.
Or if you can get them to pony up the money update the SLC to a CompactLogix processor.

Use the DH485 for the messaging

To use Devicenet is not mandatory, just is an option that I think.

I have to do that in 2 similar machines, the other machine has a 5/04 PLC and Micrologix 1400.

The problem is that the channel 0 is used by the Panelview, when i have to connect the PC to the 5/04, I have to disconnect the panelview and when i have to connect to the panelview, i have to disconnect the PLC.

Is it posible to connect the 1761-NET-ENI through the same port than the panelview in the 5/04? (The panelview just have 1 port).

Another issue that i see, is that the 1761-NET-ENI will be discontinued in few months.

On the other hand, Could I use DH485 to connect 5/04 and ML1400 and the panelview directly? Should I use some adapter/isolator?
I have never used DH485 networks, just point to point.

Thanks again
