ALARM : ACTIVE SCREENS


ALARM : ACTIVE SCREENS

1. Overview

An error code consists of:

  • The facility name and error code number

  • The severity of the error

  • The message text of the error

The error code will be displayed as follows:

FACILITY_NAME - ERROR_CODE_NUMBER Error message text

The Alarm Log screen displays a list of errors that have occurred. There are two ways to display alarms:

  • Automatically using the Active Alarm screen. This screen displays only active errors (with a severity other than WARN) that have occurred since the last time RESET was pressed.

  • Manually using the History Alarm screen. This screen displays up to the last 100 alarms, regardless of their severity. You can also display detailed information about a specific alarm. Optionally, you can set up your system to store additional alarms in an alarm log called MD:errext.ls. If you have the Extended Alarm Log option installed and set up, then this file, stored on the MD: device, will display up to the last 1000 alarms. In this case, the alarms are numbered and contain the date, time, error message, cause code, and severity. Programming events will be displayed the same as error messages but will not have cause codes or severities.

    For information on setting up the Extended Alarm Log, refer to the Software Installation Manual.

2. Displaying the Alarm Log

Procedure 1.  Displaying the Alarm Log Automatically

Conditions

  • To display the Active Alarm screen automatically,

    • Set the system variable $ER_AUTO_ENB to TRUE either on the SYSTEM Variables menu or by setting Auto display of alarm menu to TRUE on the SYSTEM Configuration menu. Then perform a Cold start.

    • An error, whose severity is either PAUSE or ABORT must have occurred.

Steps

  1. The following screen will automatically be displayed. It lists all errors with a severity other than WARN, that have occurred since the last controller RESET. The most recent error is number 1.

    SRVO-007 External emergency stop
    TEST1           LINE 15           ABORTED
    Alarm: ACTIVE
    1 SRVO-007 External emergency stop
    

  2. To toggle between the Active Alarm screen and Hist Alarm screen, press F3 (ACTIVE or HIST).

  3. If you are using an iPendant and are in Single Display Mode, you can toggle between wide screen and normal screen. Press F2, [ VIEW ] and select Wide or Normal.

  4. To disable the automatic display of all errors with a certain severity type, modify the value of the system variable $ER_SEV_NOAUTO[1-5]. These errors will still be logged in the Active Alarm screen, but they will no longer force the screen to immediately become visible. Refer to the Software Reference Manual for more detailed information about how to set these variables.

  5. To disable the automatic display of a specific error code, modify the $ER_NOAUTO.$noalm_num and $ER_NOAUTO.$er_code system variables. These errors will still be logged in the Active Alarm screen, but they will no longer force the screen to immediately become visible. Refer to the Software Reference Manual for more detailed information about how to set these variables.

  6. To display the screen that occurred immediately before the alarm, press RESET. If you have toggled between HIST and ACTIVE, the previous screen might not be available.

    When there are no active alarms (the system is not in error status), the following message will be displayed on the Active Alarm screen.

    There are no active alarms.
    Press F3(HIST) to enter alarm history screen.
     
    

    Note

    When you reset the system by pressing the RESET key, the alarms displayed on this screen are cleared.
