B Clifford (Customer) asked a question.
I need to read data in & out of a Rockwell PLC. I cannot get the 'node-red-contrib-cip-ethernet-ip', or any other new node in the Palette to install. Can you help?
I can read info from my Rockwell PLC on my PC's (v4.0.9) Node-Red using the 'node-red-contrib-cip-ethernet-ip' node. This install fails with my C2-NRED running at v3.0.2). Is it possibly a version issue?
If anyone would have an answer, it would be @Garry (Customer)
I haven't seen or heard from @Garry in ages. I miss the content.
Me too. Maybe there's a tariff to post... 😝
I think a couple of questions can help clear this up.
Please check https://cdn.automationdirect.com/static/manuals/c2userm/ch5.pdf for help setting up the C2-NRED with CLICK. Pg 5-20 has some errors you can match up with what you are seeing.
I have just checked again that I can download the node-red-contrib-cip-ethernet-ip package using the Palette Manager with out issues. Thank you
I went through the manual and confirmed that my versions are as stated.
I have not been able to get any package to install.
It does have access to the internet, the time is synced, but I am not sure about the DNS setup.
Easiest is just to have 8.8.8.8 as your DNS with possibly a Alternate of 8.8.4.4. Please also make sure the Enable user to add nodes from Network is checked. This is checked by default usually
I changed the DNS as suggested and wrote it to the PLC.with no success in inserting the package.
I don't think I have internet access still.
My laptop is on a WiFi internet connection. My PLC is connected to my laptop's rear ethernet port.
I don't know of a bridge between them. I feel that I'm much closer than I was.
My laptop and PLCs are use fixed IP addresses.
Here is the install log info:
