User-defined error output (#ERROR)

The NC command #ERROR allows the output of user-defined error messages which are further processed by the higher-level GUI (GUI = Graphical User Interface). Additional parameters offer the option of specifying the error more precisely.

The error number (ID) and error message are assigned in a user-defined file (FCT-M7// Outputting user error messages). The memory location (path) and filename are entered in the parameter P-STUP-00169.

Syntax:

#ERROR [ [ID=..] [RC=..] [MID=..] {PV<i>=..} {PM<i>=..} {PIV<i>=..} ]

ID=..

Error number:

1...1000: The numerical value determines the user-specific error number to be output.

RC=..

Error remedy class:

0: Warning, no transition to error state. Program execution is continued.

2: Error, transition to error state. Can be cleared with NC–RESET.

7: Fatal error, transition to ‘system error’ state. Requires controller restart.

MID=..

Multiple ID. Counter acts as a distinguishing feature if the #ERROR command with the same error number (ID) is used several times in an NC program. MID must be a positive integer.

PV<i>=..

Max. 5 (1 <= i <= 5) user-specific numerical values (PV1...PV5) in real format can also be output in the error message.

As of V3.1.3080.14 and V3.1.3107.48, strings can also be output, e.g.. PV1=“Test“.
Maximum length is limited to 23 characters.

PM<i>=..

The maximum of 5 (1 <= i <= 5) PM parameters (PM1...PM5) specify the meaning of the PV parameters more precisely.

0: IGNORE, value has no meaning

1: Limit value

2: Current value

3: Error value

4: Expected value

5: Corrected value

6: Logical axis number

7: Drive type

8: Logical control element number

9: State

10: Transition

11: Sender

12: Class

13: Instance

14: Identification number

15: State

16: Ring number

17: Block number

18: Lower limit value

19: Upper limit value

20: Initial value

21: Final value

PIV<i>=..

The maximum of 4 (1 <= i <= 4) PIV parameters (PIV1...PIV4) transfer additional information in real format.

For non-programmed parameters, the following default values are valid:

ID

1

RC

0

MID

0

PV1...PV5

0.0

PM1…PM5

1

PIV1...PIV4

0.0

Programing Example

prg_example

User-defined error output

; -------

; Output of warning with ID 100, multiple identifier 10

#ERROR [ID100 RC0 MID10]

; ..

; -------

; Output of warning with ID 455 with parameter

; Error 455 with parameters

; Parameter 1 – current value is 1

; Parameter 2 – incorrect value is 4.999

#ERROR [ID455 RC2 PV1=5 PV2=4.999 PM1=2 PM2=3]

; ..

; Error output with string as of V3.1.3080.14

; Expected value Text A

; Incorrect value Text B

#ERROR [ID123 RC2 PV1="Text-A" PM1=4 PV2="Text-B" PM2=3]

;…

; -------

; Fatal error 999
