m251 data log do not record continuously for multiple data log in same scan

[charankumar20]

Hi All,

I was trying to do the data log in M251 controller using the standard instructions "Log Record". If there are multiple data in the single scan then the system does not log the records. 

For Example, I am trying to capture the cold cycle as below. but it only logs first message but rese of the message is omitted.  can you please advise or guide to log the record multiple records continuously in the single scan.

IF IsFirstMastColdCycle()  THEN 

iMessage := ': Initialization : Cold Initialization';

Data_logger_Eventlog(iMessage := message, priority := 1);

message := ': Initialization : Model - TM251MESE';

Data_logger_Eventlog(iMessage := message, priority := 1);

message := ': Initialization : Program Version: 3.2.0704';

Data_logger_Eventlog(iMessage := message, priority := 1);

END_IF

Hello,

You can CONCATENATE three messages , 

Or create a case statement for a sequential log

CASE byDataPoints OF 

0: //

LogFile1.wsRecord := WCONCAT(STR1 := "Data1:  ", STR2 := REAL_TO_WSTRING(g_r1));

LogFile1.xExecute := TRUE;

IF LogFile1.xDone THEN

byDataPoints := 5;

END_IF

5: //

LogFile1.xExecute := FALSE;

byDataPoints := 10;

10:

LogFile1.wsRecord := WCONCAT(STR1 := "Data2:  ", STR2 := REAL_TO_WSTRING(g_i2));

LogFile1.xExecute := TRUE;

IF LogFile1.xDone THEN

byDataPoints := 15;

END_IF

15:

LogFile1.xExecute := FALSE;

byDataPoints := 0;

30:

// Error state

END_CASE

Hi  Engineer_MG,

thanks for the reply. But it was just an example. 

My concern is in the same Scan of the controller there are multiple logs to be done. this is not happening. 

now after several approach, I am using an work around method to log into an file system which has an array of 400 String and then using the log function to log the data. 

this was helpful from "LeTomas"

But was looking for an better solution if avaliable.
