So, each integer, float or Boolean variable will have a Modbus address associated. For example, suppose LOCAL_MOD_MAP = 1 and a float value will be monitored. Picking the F_ID1 and setting its parameters, we have: F_ID1.Tag = Tag of the float parameter necessary to monitor F_ID1.Index= Index of the first column of the parameter necessary to monitor. F_ID1.subindex = The sub index is used for parameters that have a structure. In this case it is necessary to indicate which element of the structure is being referred. See the table above The Modbus addresses given to this parameter (remember, float values use two Modbus registers) are 42641 and 42642. BAD_STATUS Parameter This parameter indicates if the Fieldbus communication is OK or no. If the correspondent bit is in logic level 1 this means there was an error during writing/reading of the respective parameter. The table below presents the values for these status values. Relation between the bits in BAD_STATUS and Modbus addresses BIT PARAMETER 0 FVALUE1 1 FVALUE2 2.221
