After updating node-red-contrib-omron-fins from version 0.3.0 to 0.5.0 I can't connect to the PLC.  
In the debug window I have this message

TypeError: buf.readUint32BE is not a function

When trying to write to the PLC.

Unfortunately the major updates I added to this node mean node V12 or greater is required.

Node V10 is eol and should really be updated. I'd recommend node v14 if you can upgrade.

Thanks.
