Receive DataBlock from Siemens S7-1200

Hello everyone !

I use OPC UA for send data to S7-1200 from Node-Red

I want to send a block of data from my Siemens S7-1200 but i don't know the datatype of my block.

For know the datatype and name of my variable i use UA Expert, but here, on my datablock i don't have datatype.

For simple variable i have the name and datatype like Int16 or Float but here nothing.

Do you have any ideas ? I'll make some pictures with.

Have a good day !
