Ignition connected to NET-ENI to SLC5/03

[gbeaker]

Hi,

I am setting up a new Ignition scada project and the only PLC is a SLC 5/03. I have the SLC connected to a NET-ENI via DF1.

I have the NET-ENI IP address set and I can ping it and also view the integrated webpage, but how do I test if it is actually connected to the SLC?

I have Ignition configured to connect to a Micrologix via Ethernet using the IP address of the NET-ENI but it doesn't appear to connect. Ignition just says "Connecting...Protocol EIP" but doesn't ever say connected.

Do anyone have any ideas?

I changed the PLC type from Micrologix to SLC5/05 and it worked fine, even though it is a 5/03. I thought the NET-ENI emulated a Micrologix, but I guess not.

Thanks for posting that followup !

The two MicroLogix with built-in Ethernet (the 1100 and 1400) have some very subtle differences in how they do PCCC over EtherNet/IP compared to the SLC-5/05 controller.

Many HMI driver makers (including Rockwell !) had to patch/upgrade their drivers to support the MicroLogix 1100 when it came out, despite its strong similarities to the SLC-5/05.

The Net-ENI falls closer to the SLC-5/05 side of the fence than the MicroLogix 1100/1400. In general, HMI data server software doesn't know what type of controller is connected on the serial side of the Net-ENI, unless they explicitly ask for the identity information (like the RSLinx/RSWho browse does).

off topic, but I recommend having your plc toggle power to the net-eni every few hours or so if this is going to be some type of remote system where someone is not available to reboot the net-eni if it locks up.

The best Net-Enis are the ones inside the garbage can.

Wow, lots of hate for the net-enis!

The system ran all weekend without issue so maybe it won't be so bad.

Now that the net-eni is in place, is it possible to go online via it and make programming changes?

I tried browsing my ethernet connection in RSlinx but nothing showed up.

When you need them the most the will fail with no reason, You have to reset power supply and they're back on duty.

Are there other 3rd party options??

Update

If I use the Ethernet driver and add the IP address to the scan list, I can go online and its actually pretty fast, faster than DH-485 anyways. However, if I try to use the Ethernet/IP driver, it does not find the net-eni. I have checked to make sure the sub-net is correct.

ive used digi one iap.

I think it will be fine just run power thru a digital out on your plc. you could setup a heartbeat or just reboot it every 4 hours or something. there is a reason why so many hate net eni, so do yourself a favor and get out ahead of it.
