F148_ERR

The error no. specified by n* is copied into the system variable sys_iSelfDiagnosticErrorCode that reads the corresponding special data register. Setting n*=0, all error numbers greater than 43 are cleared and the error LED turns off.

Parameters

Input

n* (WORD, INT, UINT)

• must be a constant

• self-diagnostic error code number, range: 0 and 100 to 299

Remarks

• Instead of using this F instruction, we recommend using the corresponding FP7 instruction: FP_SET_ERROR

• At the same time, the self-diagnostic error-flag sys_bIsSelfDiagnosticError is set and ERROR LED on the CPU is turned ON.

• The contents of the error flag sys_bIsSelfDiagnosticError and the error no. can be read and checked using Control FPWIN Pro Monitor > Special flags and registers > Basic error messages or the corresponding system variables.

• Error number areas:

  • When n* = 100 to 199, the operation is halted.

  • When n* = 200 to 299, the operation is continued.

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.
