sending active alarms to PLC through profibus

Error Code Output J527 is a paid option.

It is possible to send the alarm to the PLC with 2 GroupOutputs.
However, you will only recieve the code, not a string. So you will still have to look it up.

Make a program with (in my example called: COND_ERROR):

Quote

1: WHEN UO[6:Fault]=ON+,CALL ERROR_OUTPUT ;
2: WHEN UO[6:Fault]=OFF-,CALL ERROR_OUTPUT ;

Another program with (in my example called ERROR_OUTPUT):

Quote

CALL ERROR_TO_REG(10) ;
MONITOR COND_ERROR ;

The (10) is the register where the code is written to, when you see the karel-code below, the register after the input is also used. So you will recieve the error in register 10 and 11 with my example, choose freely your own registers.

Karel-program with:

Quote

PROGRAM error_to_reg
%NOLOCKGROUP
%NOPAUSE= COMMAND + TPENABLE + ERROR
%NOBUSYLAMP
%NOABORT = ERROR + COMMAND
%COMMENT= 'ERROR SEND'

VAR
par_no,par_typ,par_int,int_reg:INTEGER
par_real:REAL
par_str:STRING[10]

seq_num,error_code,cause_code,time_int,severity,STATUS :INTEGER
error_string,cause_string,prog_nam:STRING[40]
prog_stop:BOOLEAN

BEGIN
par_no=1
GET_TPE_PRM(par_no,par_typ,par_int,par_real,par_str,STATUS)
IF (par_typ=1) AND (STATUS=0)THEN
int_reg=par_int
ENDIF

ERR_DATA(MAXINT, error_code, error_string, cause_code, cause_string, time_int,severity, prog_nam)
SET_INT_REG( int_reg,error_code DIV 1000,STATUS)
SET_INT_REG( int_reg+1,error_code MOD 1000,STATUS)

END error_to_reg

Perform a controlled start
Change next variable: $TPP_MON.$GLOBAL_MT
To $TPP_MON.$GLOBAL_MT=2

Restart controller with cold start [FCTN -> Cold Start]

Make a condition monitor with ERROR_OUTPUT
Menu > 0 > Status > Type: Condition
System: COND_ERROR

Register 10 = Facility Code
Register 11 = Error Code

Example: Facility Code: 11 stands for SRVO

Good luck!

Hi,

Never worked with slave devices before. What kind of slave devices do you mean?

Sorry, really don't know how to do that.
