Representation

Guidelines - Software creation

The following function codes (FC) are supported: 3, 4 and 6 The following modes are supported: Modbus RTU and Modbus TCP The following transmission rates are supported (RTU): ????? The Modbus address specifications must be used for addressing.

&#xNAN;************** &#xNAN;* Functions * &#xNAN;**************

In this function block, the relevant actual values (registers 0 - 37) of an indoor unit are captured and evaluated (FC03: addresses XXX0 - XX37). The indoor unit is selected via the input byIUAddress in the range 1 - 64. The actual values of an indoor unit are available in the structure element stIndoorUnits_ActualValues_1 available. Registers 0 - 14, 16 - 17 and 20 - 38 are read. Registers 15 and 18 - 19 may only be written. The registers in the range 39 - 61 are not read, as they are not needed for the specific application.

Measured values - matching: unclear class

InOut:

Scope	Name	Type	Initial	Comment
Input	xEn	BOOL	TRUE	Enable / disable communication (TRUE = enable)
