you have a permission problem with fire base. Check the username and password are correct, and see if you can do what you want outside of Node-RED to check if it is a problem with firebase or Node-RED

thank you  
it was issue from firebase.  
now it is working.

i am sending plc data to fire base and its done successfully through MODBUS TCPIP.

i have some questions regarding NODE-RED.

> how many modbus register can read through NODE-RED.(is there limitation?)  
> to run the NODE-RED internet connectivity is require compulsory?( any solution to run NODE-RED without internet.)

please guide me for the same.

Your first question is about a contrib-node. Your best bet is probably to ask on the github page of the node you are using.

You do not need an internet connection to use Node-RED

If you mean the core Node-RED the license is available here [https://github.com/node-red/node-red/blob/master/LICENSE](https://github.com/node-red/node-red/blob/master/LICENSE) for you to read.

Third party contrib nodes that you install in Node-RED may have different license terms and you should check these before you install any node
