Hello,

in this case Holding Register can be created (check MB_Slave/Server in TIA). Try create DB with no optimized access and structure with 5 REALs and 5 WORDs. Set some values to them (via Watch table f.ex.) and start configure on Scada Modbus general FC3 code (hope this is system on your Scada). Then try poll this PLC (DB) Holding register from first register (here REAL will be need read as 2 registers generally and WORD as one register). Via this system you can have correct data from PLC to Scada. In some cases (check for sure after receive in Scada) swap of bytes / words is needed, for this check some cfg of Scada.
