by default the string value of struct member is put in the table field
via Text variable :: DataLogger.LogArr[INDEX].FlagAllame

just put this in the property Toggle color:

DataLogger.LogArr[INDEX].FlagAllame

Hi guys,

I am still studing codesys system, I solved many trouble I had but I find always new trouble...
Melius est abundare quam deficere 😊

Well, I explane the situation:
I created an array of type StrArr, a STRUCT with several date of different nature to create a custom datalogger with WSTRING,BOOL, DATE and TIME variables.
I am showing it, in the visu section, throughout a table, https://help.codesys.com/webapp/_visu_elem_table;product=core_visualization;version=3.5.17.0#element-property-columns
In the column 0, that points to the FlagAllarme variable of the STRUCT, I am tring to use the template option.
I would like to show a rectangle, in that column, that changes its color (red/green) on the base of a boolean variable conteined in the StrArr STRUCT.

I paste a bit of code to help the understaing ( I apoligeze for the italian comment).
This is the struct:

TYPE StrArr :
STRUCT
    FlagAllarme : BOOL;
    DataDiAccesso : DATE ;
    OraDiAccesso : TIME;
    OperatoreLoggato : WSTRING;
    Evento : WSTRING;
END_STRUCT
END_TYPE

The following is the PRG I call to write into the array:

PROGRAM DataLogger

VAR_INPUT
    vEvento : WSTRING;  // Evento da registrare nel data loggher
    AlarmFlag : BOOL;   // Flag di distinzione tra allarmi e semplici eventi
END_VAR


    LogArr[indice].FlagAllarme := AlarmFlag;    // Flag di allarme 1 se allarme 0 se manovra
    LogArr[indice].DataDiAccesso := DT_TO_DATE(PLC_PRG.dtSystemTime);   // acquisizione data
    LogArr[indice].OraDiAccesso := DT_TO_TIME(PLC_PRG.dtSystemTime);    // acquisizione ora
    LogArr[indice].Evento := vEvento;   // Acquisizione evento
    LogArr[indice].OperatoreLoggato := VisuElems.CurrentFullUserName;   // acquisizione operatore loggato
    indice := indice + 1;   // incremento dell'indice dell'array

Now the trouble is when I put the "COLOR VARIABLE" in the visu secion I write the several line but no one of them works.

DataLogger.LogArra[].FlagAllame
DataLogger.LogArra[DataLogger.indice].FlagAllame
DataLogger.LogArra[DataLogger.indice].FlagAllame = 0/1

the compiler gives me always the same error:
C0007: Expression expected instead of ']'

If I put this:
(DataLogger.LogArra[DataLogger.indice].FlagAllame = 0/1)
The application runs but the colors doesn't switch.

Does someone know where the error is?

Many thanks,

Riccardo
