Hello, Good day!  
I want to ask if possible to use peripheral port(USB type B) as communication to read and write data in PLC? I have this CJ2M CPU11 PLC, the ports available are 1 RS232C (connected to HMI) and 1 peripheral port.  
I have raspi3 connected to peripheral port and un-till now I cant get any data(serial port node).

please help me!

If you have an ETN21 or EIP21 card you can easily access data over Ethernet/FINS with [node-red-contrib-omron-fins](https://flows.nodered.org/node/node-red-contrib-omron-fins)

If not, hold tight a few days as I am updating `node-red-contrib-omron-fins` to aid communication with hostlink/serial protocols

Hi steve-Mcl, thank you for your response,  
No RS232, no Rs485 , no Ethernet port. Only peripheral port is available.  
I just want to ask if I can use hostlink/serial protocols with peripheral port using USB B type cable.  
currently I am trying to get data using serial port node and omronplc node. but still no luck..

Hi @Vanj I have added a beta version of `node-red-contrib-omron-fins` which includes `c-mode` nodes.

> OMRON FINS Ethernet protocol functions 'Read' and 'write' for communicating with OMRON PLCs from node-red. Latest version: 0.5.0, last published: 2 years ago. Start using node-red-contrib-omron-fins in your project by running \`npm i...

To install...

```bash
cd ~/.node-red
npm i node-red-contrib-omron-fins@1.0.0-beta-0

```

I dont have access to a peripheral / hostlink cable or PLC to test so would be grateful if you could test it and feedback. Ask here if you have questions on usage.
