Read data memory node-omron-read

is there more documentation on how to put address on node-omron-read like CIO Memory,...
How should I set an internal boolean variable (I/O Channel) address on FINS read node?

Hi i have just poublised a new node node-red-contrib-omron-fins

It is not on NPM for now but you can install manually from a command line.

If you would like to test it, then you can install as follows...

CD to your actual .node-red directory then

npm install Steve-Mcl/node-red-contrib-omron-fins

The built in help in the info panel on the side-bar should be enough for you to get by.

Thanks alot. I will test it as soon as possible.

I say its new - its newly published (been using privately for around 1 year) so its fairly stable.

Probably could do with some user interface improvements but should work as is.

Can someone share an example how to use this node?
When I read from the PLC it gives an error "Write not possible, cannot change"

Share your flow and a screenshot please. The node definitely works (I wrote it and use it in a production environment).

Please also state the following...

  • mode of plc (run / monitor)
  • plc model
  • PLC settings including fins node number, fins network number, fins port, the dial settings on the from of plc Ethernet card

Edit. To be 100% sure - you are using this node-red-contrib-omron-fins right?

My PLC is an CJ1M-CPU12
Ip address is - local network = 1
port 9600, node number 16

question: Have you setup the routing table (i.e. network 1 is definitely the ETN/EIP card?)

question: what are the 2 node number dials set to on ETN/EIP card?


DNA: 1
DA1: 0
DA2: 0
SNA: 1
SA1: last_octet_of_PC_IP
SA2: 0

and try...

DNA: 0
DA1: decimal-value-of-node-dials-on-ETN/EIP
DA2: 0
SNA: 0
SA1: last_octet_of_PC_IP
SA2: 0

@jaccoit would be nice if you could feedback if this worked (or not) and described what you did for future users.

Will do....

Still not working, I tried both


This is correct?



What is the subnet mask on PLC and PC?

Can you screenshot CX Programmer -> IO Table -> ETN properties (IP TAB and FINS UDP tab)

Ok this was stupid.....

SA1: last_octet_of_PC_IP

I didn't give the right octed of my PC address.

I is working now, thanks a lot.

Would you be kind enough to post a screen shot of your settings and your PLC setup to assist future readers?
