  - Funtions A
    - abortFileTransfer()
      The function abortFileTransfer() aborts all file transfers of the stated manager.
    - abs()
      Returns the absolute value of a value.
    - access()
      Queries the access mode of the file or directory with the specified path name.
    - acGetRefACType()
      Returns a AC type name, if the leaf dpeName is referenced to an AC type, otherwise an empty string.
    - acos()
      Returns the arc cosine in the radian measure.
    - activateMode()
      Switches the module to normal operating mode.
    - addGlobal()
      Creates a variable and makes it into a control-wide variable.
    - addGroup()
      Adds a group of shapes or a layout to a panel.
    - addGroupPVSS()
      Adds a user group of an external authentication system to the WinCC OA user administration.
    - addShape()
      Adds a new shape into a panel.
    - addSymbol()
      Adds a panel reference in a panel or layout at a later time during run time. To suppress the Initialize scripts of the reference the function createSymbol() can be used instead.

      Adds a user of an external authentication system to the WinCC OA user administration.
    - addUserToGroupPVSS()
      Adds a WinCC OA user to a user group in the WinCC OA user administration.
    - aes256Decrypt()
      The function allows to decrypt an encrypted information with the AES-256 algorithm.

      The function allows to encrypt the passed information with the AES-256 algorithm.
    - afterLogin()
      After successful login displays the required panel.
    - alertConnect()
      Registers the function work() for call with resulting alerts.
    - alertDisconnect()

    - alertGet()
      Queries only the last alert attributes of a data point.
    - alertGetPeriod()
      Reads the values of the specified alert attributes of the data point elements for which alerts were triggered.
    - alertSet()

      Allows data point attributes to be set in a similar way to dpSet(). Additionally the timestamp can be set manually.
    - alertSetWait()
      Allows data point attributes to be set in a similar way to alertSet()/dpSetWait().
    - animate()
      With the function animate() you can create animations.
    - animateWait()
      With the function animateWait() you can create animations and wait for them to finish.
    - asin()
      Returns the arc sine in the radian measure.

alertDisconnect()

Unregisters the function work() from call when changes are made to the values.

Synopsis

int alertDisconnect([class object,] string|function_ptr work, string alert1 [, string alert2 ...]|dyn_string alert_list);

Parameters


Parameter	Meaning
object	An object of a Control++ class.
work	Name of the work function that is called when alerts occur Or a function pointer to the work function (callback function).
alert1, alert2, ... \| alert_list	Alert handling attributes or a list of alert handling attributes (dyn_string).

Return Value

If successful 0, in the event of an error -1.

Errors

Errors can be retrieved with getLastError() . The return value is then the appropriate error code. An alert is issued in the event of non-existent data points, incorrect parameter transfers or spelling errors.

Description

The function alertDisconnect() unregisters the function work() from the call when changes are made to the values of the alert handling attributes alert1, alert2, ... The work function is no longer executed spontaneously.

Example

main()
{
  alertDisconnect("work",":_alert_hdl.._text",":_alert_hdl.._visible");
}

You can find an example of how to use a Control++ class instance in an alertDisconnect function in the chapter alertConnect().

Assignment

Alert handling, waiting control function
