[MohammedAvensis]

I am Communicating with a slave device and I able to read the variables value from 2 WORD Locations and after Combining the WORDs into a single DWORD and unlike Eco Structure Machine Expert I am not able to convert the DWORD into a Real Value using Unions or pointers in Eco Structure Machine Expert HVAC ..

Dear Mohammed,

there is a trick for TM172P to read 32 bits in  modbus.

Please see the DEMO in attachment for TM172P and for TM173O.

Best regards

Additional to Marcos tips, since ESME HVAC 1.7 the function to creat a REAL from two WORD is included in the standard librarys 

The syntax is a little bit different in ESME HVAC comparing to Codesys based ESME 

@ is used instead of ^
