Mode for analog components with an analog reference output and a digital order
 output.

 The object handles an object graph with Auto/Man buttons to switch mode
 and Start/Stop buttons to control the unit in manual mode.

 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 prioriy 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 Start/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 Start/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 Start/Stop
                   buttons of the local panel is used. To disable this
                   mode, set OpNoLocal to 1.

 The Start/Stop buttons can also be configured to show On/Off instead.

 The object is for example used in BaseFcPPO3MotorAggr, a motor aggregate with
 frequency converter.

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

 - The Start button has toggle function, i.e. if the unit is already
   started it will be stopped.

 - The Auto/Man buttons changes mode in remote control.

 - In local mode, the local indicator is yellow, and the Start/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 Start/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 Start indicator displays status of the feedback from the controlled
   unit.

Configuration

 The Mode object CompModeA handles an analog and a digitl order output that
 can be configured in many different ways. It contains the functions

 - Start/Stop order, or alternatively On/Off.
 - Error handling for maneuvering, 5 alarm.
 - Buttons are dimmed and made insensitive to avoid incorrect handling.

 The order output is controlled in three different ways

 - by the ExtStart input pin of the function object, when the object
   is in Auto mode.
 - from the Start/Stop buttons in the object graph, whan 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.

 -StartStop     Text of Start/Stop buttons in object graph is Start/Stop.
 -OnOff         Text of Start/Stop buttons is On/Off.

 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 is controlled by the digital input
 ExtStart and the analog input RefAuto in the function object. The ExtControl
 input is not used in this configuration.

 By setting OpIntOnly to 1, the extern Auto/Man control from the plc program
 is disabled, i.e. the input ExtStart and AutoRef are not used.

 The 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
 output is now controlled by the ExtStart input, and the Start/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 Start/Stop in manual
 mode is controlled outside the object. By setting OpExtOnly to 1 also the
 Start/Stop buttons are removed in the graph and the control of the order output
 is handled by the ExtStart input only, i.e. the mode is not handled in the object
 and no buttons are visible.

 The figure shows when Auto/Man mode is controlled by the ExtControl input
 of the function object, the manual control is handled outside the object.
 To get this configuration, set OpExtOnly to 1. The outputs are now controlled
 only by the ExtStart and AutoRef inputs. This configuration is rarely used.

 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.

 The Start indication is green when the Feedback input is 1. Normally the
 feedback of the unit is connected to the Feedback input.

 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.

 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.

 If the error output is set in Local or Auto mode, actions should be taken
 to avoid unwanted restarts, by resetting the control order to the inputs
 ExtStart and LocalStart.

 For plc coding the function object CompModeAFo is used.

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

 be controlled from the Start/Stop buttons in the object graph. the Auto/Man
 buttons are removed, and the extern control inputs of the function object are
 disabled.

 Configuration attribute to not handle Local mode.
