Problems Reading MD memory Variables

[motosierra1141]

Describe the bug

I have been trying to connect my PLC to node red, i can read variables like boolean and int, but when i want to read a MD variable a memory that is a Real variable it show a number like 1077095984 a huge number, when i connect to the PLC to see the real value of variables i can see that the value it is very different to the number i see in node red

To Reproduce

1.- try to read a Variable type Real that it is a MD a memory i use a MDIXXX in node red

Expected behavior

I try to see with debug the value that i see in the PLC monitoring the variables in Tia Portal

Screenshots

in tia portal this variable it is between 2.5 and 4

if you click on the variable in node red it change into a date format, very weird

Logs

If applicable, attach the Node-RED logs with the "Verbose" option on the configuration node set to "On"
