the float value is moved forward by one register

[vlastikcocek]

Hello,
I send a float value to regitstr 12 PLC Delta and the float is in register 11
can you advise me where to solve the issue?

logger.info(master.execute(1, cst.WRITE_MULTIPLE_REGISTERS, starting_address=12, output_value=[3.99], data_format='>f'))

Thank you
Vlastik
