Digital Supervisory.

 Supervises a binary quantity in an arbitrary object in
 regard to alarm position. CtrlPosition specifies if
 true or false constitutes the alarm position. The alarm
 message can be delayed by a time specified by TimerTime.

 The DSup object reacts in two ways when the quantity is
 in the alarm position:

 1  the act-output is unconditionally set to indicate
    alarm state.

 2  after the time defined by TimerTime a message is
    sent to the out units, for instance operator
    stations. This reaction can be suppressed by means
    of DetectOn.

 A message contains the text string DetectText as well
 as flags ( see EventFlags) to handle supplementary
 activities.
 Different types of activities exist; (see EventType )

 - ALARM   The message remains as long as the alarm
         position exists and no acknowledgement is

 - INFO    If the message demands an acknowledgement
         this is sent to the info part of the alarm
         window from, where it can be acknowledged,
         otherwise only to the event list.

         An acknowledgeable info-message disappears
         from the info part of the alarm window as
         soon as it has been acknowledged without
         waiting for return to normal state. As soon
         as the supervised signal that gave an info
         message, reaches the same position again and
         this has been detected a new message is generated.


 The ALARM messages are given different priorities, (
 see EventPriority ). The texts of A- respectively
 B-alarms are displayed both in the alarm window and the
 alarm list. Acknowledgement can be done from both
 places. In the alarm window the number of
 unacknowledged C- resp. D-alarms is shown, while the
 text is put into the alarm list, where the
 acknowledgement can be done too.

 Different types of out units exist:

 - OPERATOR: The select list is defined by an attribute
   in a User object.
 - PRINTER:    The select list is defined by an
   attribute in an EventPrinter
   object.

 Note! A message created by an DSup object gets the same
 identity as the supervised object. The attribute
 SelectList in out unit objects, e.g. User objects,
 specifies the hierarchies from which messages are to be
 received.

 Supervision of a trailing edge can be done when the In-signal
 has been inverted.

 The supervised quantity may belongs to an arbitrary
 object. This means not only signal objects but also
 other objects may supervised; e.g. attributes in a
 user-defined object.
 It is possible to configure both ASup and DSup objects
 in different ways. At configuring in a PLC program the
 PLC job will do the supervision. When the objects are
 configured outside PLC program, then it is done by the Configuration
 Editor and the eventmonitor takes care of the
 supervision.

• ASup

 Supervised signal. Can be inverted to supervise a false
 signal.

 Specifies whether to enable or disable the supervision.
 Note that blocking is done when Control is FALSE. The
 input signal can be inverted.

 FALSE disables the supervision and TRUE or open input
 enables the supervision.

 Specifies the status of supervised quantity. FALSE
 means normal state and TRUE means alarm state.
 The output signal can for instance be used to activate
 an action sequence at alarm state.

 Specifies if the alarm state has been acknowledged or
 not. FALSE means that unacknowledged alarm exists. The
 output is set TRUE after booting and when the alarm
 state has been acknowledged.

 Specifies whether to enable or disable the blocking. No
 messages from the supervision object will be sent away
 as long as the object is blocked. The blocking does not
 influence on the 'act' output of the object.

 FALSE disables the the blocking and TRUE enables the
 blocking. When a supervisory object in alarm position
 is blocked current messages will be cancelled.
 Blocking /deblocking is done by means of the 'Alarm
 Blocking Window' in the operator environment.

 Optional text to describe the object. It is used in the
 picture Alarm Limits which is activated from the
 operator window.

 Specifies whether to enable or disable the action,
 which at alarm state implies DetectText to be sent or
 not. FALSE means that no message will be sent at alarm
 state; TRUE means that DetectText is sent at alarm
 state.

 Alarm message. Optional text which will be written out
 at alarm state if DetectOn is TRUE.

 Return message. Text which will be written in the event
 list at return to normal state.

 Specifies the type of the message (=DetectText ) which
 will be sent at alarm state.
 ALARM -- 64 The message always requires an
             acknowledgement and sent to the alarm

 INFO  -- 32 If the message requires acknowledgement is
             it sent to the info part of the alarm
             window and the event list, otherwise only

 Priorities concerning alarm messages.

  -- 67   A-alarm; highest priority. (=43Hex)
  -- 66   B-alarm  (= 42Hex)
  -- 65   C-alarm  (= 41Hex)
  -- 64   D-alarm ; lowest priority. (=40Hex)

 Bit map. A combination of flags can be attached to the
 message. The possible values are as follows:

 -- Return (1)  If this flag exists the return message ReturnText
                will be sent to the event lists at the out units,
 -- Ack (2)     If this flag exists the acknowledgement message
                will be sent to the event lists at the out-units,
 -- Bell(4)     If the single out unit has a beep-function this
                will be activated when the message is received.
 -- Force (8)   The message is sent to every out unit regardless
 -- InfoWindow (16)  If the message is of the type INFO it will be
                placed in the event list. If this flag exists the
                message is also placed in the INFO square of the
                alarm window where acknowledgement is to be done.
 -- Returned (32) The alarm status is set to returned already
                when the alarm is emitted.
 -- NoObject (64) Not used
 -- Email (128) The message will be handled by the email server
                and forwarded to the specified receiver.
 -- SMS (256)   The message will be handled by the SMS server
                and forwarded to the specified receiver.
 -- UserDetectTime (512) DetectTime is set by the user when the
                alarm condition is set.

 Reference to a sound object, that defines the sound at the operator
 place when the alarm is active. If no sound object is supplied, an
 ordinary beep is used. The sound object should be of class Sound
 or SoundSequence

 Optional text supplying more information about the event.
 The more text can for example contain actions to be made when an alarm is detected.

 Recipient for epost and mms alarms.
 The recipient is a user defined in the user database in the
 current system group.
 Recipient can also be a list of users separated by comma, eg
 'dennis, jimmy'. Also symbols defined in the Symbol table in
 the PostConfig object can be used. Symbols should be referenced
 with a $ sign before the symbol name, eg '$on_duty'.

 The users should be defined in the current system group or in a
 subgroup to this, If a subgroup is used, the subgroup should
 be specified in the recipient name, eg 'sms.dennis'.

 Attribute is filled in by the user if the input named
 IN is left open. If the input is connected the names
 are filled in by the PROVIEW/R system at compilation.

 Status value. Bit map containing 16 bits where the 8
 least significant bits denote the state and the 8 most
 significant bits the priority.
 The state is a combination of:

    -- 0    Normal state
    -- 1    Alarm state
    -- 2    Unacknowledged alarm
 The priority is one of the priorities EventPriority.

 The following status can exist:
    EventPriority + 1 => Priority + alarm state
    EventPriority + 3 => Priority + unacknowledged alarm
 and alarm state

 Used internal at the event detection.

 Specifies if an alarm state will be detected or not.
 FALSE means that an alarm state will not be detected;
 TRUE means that an alarm state will be detected.

 Specifies if the message has already been sent to the
 out units (or more precisely the message handler) or
 not. TRUE means that the message has been sent.

 Date and time when alarm state was detected.

 Specifies if the object has returned to normal state or
 not. TRUE means that the object has returned to normal
 state.

 Specifies if the return message, ReturnText, has been
 sent to the out units or not. TRUE means that the
 return message has been sent.

 Date and time when the last return to normal was
 detected.

 Date and time when the last acknowledgement of normal
 state was detected.

 Identity of the out unit (operator) which made an
 acknowledgement.

 Value of supervised parameter at TimeOfDetect.

 Specifies if alarm position is TRUE or FALSE.
 FALSE = When the In-signal makes the transition
 1 --> 0 => alarm state
 We prefer to avoid this case by inversion of the input signal
 TRUE  = When the In-signal makes the transition
 0 --> 1 => alarm state. This is the normal case.

 Used by the SuppressSup object to suppress the alarm.

 Indicates an active timer.

 Points to the next element in the timer queue.

 Number of remaining ticks.

 Points to a Do or Dv object or, if these are not used,
 to TimerDoDum. After a time of TimerTime the signal
 specified by TimerDo is cleared.

 Delay in seconds. Specifies when, since an alarm state
 has occurred, the message will be sent. If the alarm
 state disappears before the time has elapsed no message
 is generated.
 TimerTime >= the executing period of the PLC program.

 Dummy. If TimerDoDum does not point to a Do or Dv
 object it points to this attribute.

 Identity of this object is set at load file creation.
 Used by the run time system.

 The operator's authorities to change TimerTime. Not
 implemented.

  0   -- Changes not allowed.
  !=0 -- Changes allowed.

 Specifies a valid interval at changes made by the
 operator on TimerTime.

 TimerMin <= TimerTime <= TimerMax

 Specifies if DetectText is to be displayed in the
 symbol of the DSup object or not. FALSE means no
 displaying and TRUE displaying.

 'Attribute' is assigned a value that should not be changed.
 Normally the 'Attribute' value is fetched from the object connected
 to the In input pin. If LockAttribute is set, and Attribute is
 assigned a value, this value will not be changed by the compiler.
