Omron fins connection to NSJ

[zdinkle]

Hello,

I am just getting into a project connecting our industrial plcs to a node red server to display machine metrics. I have connected to other Omron plcs using fins but am struggling with a few Omron NSJ style hmi/plc combination units. As there is no direct selection for the NSJ units in the fins setup does anyone have a work around for these units?

any help or direction would be appreciated.

thanks

Hi. Welcome to the forum.

As there is no direct selection for the NSJ units in the fins setup does anyone have a work around for these units?

Under the hood, the main difference is the memory area ranges. Choosing CJ will be fine / compatible.

As for addressing, make sure you add a direct address in the AT property to your tag tags as per the info in the readme

For efficiency and consistency, avoid the desire to do single addresses and do larger arrays and then use the buffer-parser nodes to make sense of the data. If you are unsure why I am saying that, read this: Modernize your legacy industrial data. Part 2. • FlowFuse

Thanks for the quick response on this.
I am glad to know there is a way but I have not found my solution yet.
Attached are pictures from the NSJ ethernet settings and node red fins connection.
IT has assured me there is full communication between the unit and server and I can ping the plc.

Are there any issues with how i have this set up?

I'm pretty sure that photo of the HMI is the settings for connecting to a FINS device not for setting up FINS on the internal PLC. I think you need to use the programmer tool to set up FINS. Can you show me those settings?

Steve your reply got me down the right path on the Omron side.
I have found that the communication settings are in the cx-designer for the hmi.
I had set the ethernet ip correctly but did not have a connection listed for either my laptop or the server for the fins to recognize.
With this change I was able to read the plc from the ethernet port to my laptop.
below is the ethernet settings where I found my error.
Unfortunately, I still cannot connect from the server side of things as shown below.
Do you see any other settings I may have missed in setting up this connection

cx-programmer settings i was able to connect with from my laptop

You have the protocol set for TCP. Try UDP.
