Hi, I Have a little question about omron fins. I can connect with the plc omron and I can read the values of the memory areas. But each area gives me a value which is 16bit converted to decimal.  
So, to read a datum that resides in address d33 and d34 how can I do?  
Each address returns a converted decimal.  
So currently I have a node returning me the converted decimal of addres 33 and another converted decimal of address 34.  
d33 = value (16bit)  
d34 = value (16bit)

As it says in the [read me](https://flows.nodered.org/node/node-red-contrib-omron-fins) ..

> In essence, you pull a bunch of data from the plc in one go & convert it all in the buffer-parser node to almost any format you could wish for (bits, floats, 32bit signed / unsigned, byteswapping etc etc). It can do 1 or many conversions all at once. It can send a grouped item (object) or individual items with a topic ready for pushing your data directly from the PLC to MQTT.
