Mode for components with digital increment and decrement orders.
 The CompModeD2 object handles two digital order outputs and and object
 graph with Auto/Man and Incr/Decr/Stop buttons. It also handles optional
 limit switches.

 The mode object handles several modes and configurations. The controlled
 unit can be handled locally or remotely.

 - Local mode    The unit is controlled from a local panel close to the drive.

 - Remote mode   The unit is controlled from the control system, either by
                 the operator from the object graph, or by PLC program.

 The local mode has higher priority than the remote.

 The mode handling also contains an extern and intern mode.

 - Intern mode   The unit is handled by the built-in Auto/Man function,
                 basically from the Auto/Man buttons in the object graph.

 - Extern mode   The built-in Auto/Man function is not used. Auto/Man is
                 handled from the plc program and other graphs.

 Which of these modes that are present depends on the configuration.

 Modes that can be configured

 - Intern          Auto/Manual mode is controlled from buttons in the
                   object graph. This is the default configuration.
 - Extern          Auto/Manual mode is controlled from the PLC program.
                   The Auto/Man buttons are removed from the object graph
                   but the Incr/Decr/Stop buttons are still present.
                   Set attribute OpIntOnly to 1.
 - Extern only     Auto/Manual mode is controlled from the PLC program.
                   No Auto/Man or IncrDecr/Stop  buttons are present in the
                   object graph. Set attribute OpExtOnly to 1.
 - Intern only     Only manual mode is present, and the Auto/Man buttons
                   are removed. Set OpIntOnly to 1.
 - Local           When the local panel is activated, and the Incr/Decr
                   buttons of the local panel is used. To disable this
                   mode, set OpNoLocal to 1.

 The Incr/Decr buttons can also be configured to show Up/Down, Forw/Back or
 Open/Close instead.

 The Auto/Man buttons changes mode in remote control, and the Incr/Decr/Stop
 buttons are used to manually control the drive at remote control.

 - The Incr/Decr buttons have toggle function, i.e. if the button is already
   activated it will stop the unit.

 - The Auto/Man buttons are used to mode in remote control.

 - In local mode, the local indicator is yellow, and the Incr/Decr/Stop buttons
   are dimmed. Control via Auto/Man is disabled.

 - The Extern indicator (not present in the graph above) displays when
   Auto/Man is controlled externally and the Auto/Man buttons are hidden.

 - When the mode is Auto, the Incr/Decr/Stop buttons are dimmed.

 - If mode extern only is configured, both the Auto/Man and the Start/Stop
   buttons are hidden, and the Extern indicator is always green. Auto/Man
   should be displayed in some other way.

 - The Incr/Decr indicators display status of the feedback, usually the contactor
   feedback.

 - The Limit Switches indicators display status of extern feedback, normally
   limit switches.

Configuration

 The Mode object CompModeD2 handles two digital order output that can be
 configured in many different ways. It contains the functions

 - Increase and decrease order.
 - Error handling for position feedback and maneuvering, 5 alarm.
 - Buttons are dimmed and made insensitive to avoid incorrect handling.

 The order outputs are controlled in three different ways

 - by the ExtStart input pin of the function object, when the object
   is in Auto mode.
 - from the Incr/Decr/Stop buttons in the object graph, when the object
   is in Manual mode.
 - by the LocalStart input pin of the function object, when the object
   is in local mode.

 Note that only one of the configuration attributes, OpExtAndIntMan, OpIntOnly
 and OpExtOnly should be set.

 -IncrDecr      Text of Incr/Decr buttons in object graph is Incr/Decr.
 -UpDown        Text of Incr/Decr buttons is On/Off.
 -ForwBack      Text of Incr/Decr buttons is Forw/Back.
 -OpenClose     Text of Incr/Decr buttons is Open/Close.

 Possible end limit switches are connected to inputs in the function object.
 If no limit switches are present, OpNoLimitSwitch set set to 1, and the limit
 switch indicators are removed from the object graph.

 The stop button can be removed. The output order is then set, as long as the
 Incr/Decr buttons are pressed. To get this function, set OpNoStopButton to 1.

 The figure displays a configuration (the default), where all the functions
 are activated. The operator selects auto or manual mode with the buttons
 Auto/Man. In auto the order outputs are controlled by the ExtIncr and
 ExtDecr inputs of the function object. The ExtControl input is not used
 in this configuration.

 The left figure shows when Auto/Man mode is controlled by the ExtControl input
 of the function object. Auto is activated by setting ExtControl to 1. The order
 outputs are now controlled by the ExtIncr and ExtDecr inputs, and the
 Incr/Decr/Stop buttons are dimmed. To get this configuration, set OpExtAndIntMan
 to 1. This is the only configuration alternative where the ExtControl input is
 used.

 The right figure shows when Auto/Man mode and maneuvering Incr/Decr/Stop in manual
 mode is controlled outside the object. By setting OpExtOnly to 1 also the
 Incr/Decr/Stop buttons are removed in the graph and the control of the order outputs
 are handled by the ExtIncr and ExtDecr inputs only, i.e. the mode is not handled
 in the object and no buttons are visible.

 The figure shows when manual mode only is configured. The ExtIncr, ExtDecr and Local
 inputs of the function object is not used. The Auto/Man and Local indicator
 are invisible. To get this configuration, set OpIntOnly and OpNoLocal to 1.

 The figure shows when local mode is activated, i.e the LocalMod input is 1.
 The control of the order output is now handled by pushbuttons on a local panel
 via inputs in the function object. Local mode disables auto and manual control,
 i.e. local control has highest priority.

 Normally the Incr/Decr buttons have a toggle function, but if OpNoStopButton
 is set to 1, the order output is set as long the buttons are pressed instead.
 The Stop button in removed in this configuration.

 The Incr/Decr indications are green when the feedback for the orders, FeedbackIncr
 or FeedbackDecr, is high. These inputs of the function object are normally connected
 to contactor feedback.

 If limit switches are present the manual increment and decrement output is set
 until the corresponding limit switch is affected, or until the OrderTimeLimit
 (default 10 s) is reached. If OrderTimeLimit is reached, the Error output it
 set and an alarm is sent. Normally the mode is switched to manual, if not
 OpNoAutoToMan is configured.

 If the Ready input is reset, the normal behavior is to force the object to
 manual mode. This force can be disabled by setting OpNoAutoToMan to 1.
 The ForceMan input of the function object can also force the object into
 manual mode. This function is not affected of the OpNoAutoToMan setting.

 If ready is 0 the order output is interlocked in all different modes.

 If the object is interlocked when the operator tries to change mode, an
 alarm is sent. Normally buttons are dimmed to avoid incorrect actions.

 NoteWhen Auto/Man is controlled externally, it is important to look
 at the Error output and reset any control order to inhibit unwanted
 restarts.

 For plc coding the function object CompModeD2Fo is used.

 Create a function object in the plc editor and connect it to the current
 object with the connect function.
