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 data 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.LogArr[].FlagAllame
DataLogger.LogArr[DataLogger.indice].FlagAllame
DataLogger.LogArr[DataLogger.indice].FlagAllame = 0/1

the compiler gives me always the same error:

C0007: Expression expected instead of ']'

If I put this:

(DataLogger.LogArr[DataLogger.indice].FlagAllame = 0/1)

The application runs but the colors doesn't switch.

Does someone know where the error is?

Many thanks,

Riccardo

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 Fless thanks for the reaply,

You are great!!!
I didn't find nothing about INDEX variable, but it works properly.

Many Thanks.

I wish you very good Celebrations.

Riccardo
