FP_SET_ERROR

Set/reset self-diagnostic error

The error no. specified by n is copied into the system variable sys_iSelfDiagnosticErrorCode that reads the corresponding special data register.

Parameters

Input

n (INT)

must be a constant

Self-diagnostic error code number, range: 0 and 100 to 299
For FP7: range 0! and 1000–2999

Remarks

The contents of the system variable sys_iSelfDiagnosticErrorCode and the error no. can be read and checked using Control FPWIN Pro “Monitor” > “Special flags and registers” > “Basic error messages”.

Error number areas:

When n=0, all error numbers greater than 43 are cleared and the error LED turns off.
When n=100–199, the operation is halted.
When n=200–299, the operation is continued.

For FP7:

When n = 0!, no error
When n < 1000, operation error occurs
When 1000 < n < 1999, PLC stops
When 2000 < n < 2999, error occurs but PLC continues

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE): if n exceeds the limit.
sys_bIsOperationErrorNonHold (turns to TRUE for one scan): if n exceeds the limit.

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		bStart: BOOL:=FALSE;
			(*activates the function*)
	END_VAR

POU body

When the variable bStart is set to TRUE, the function is carried out.
