Base component for a supervised analog sensor.

 The object has four supervised limits LowLow, Low, High and HighHigh.
 The limits can be enabled/disabled and limits are adjustable from the
 object graph.

 The object also contains a Trend.

 Default dynamics:
 - colored yellow when the High or Low limit is activated.
 - colored red when the HighHigh or LowLow limit is activated.

 The type of sensor can be viewed with a letter in the symbol.

 The popup menu is not configured as default, but it is advisable to
 configure the menu.

Configuration

 The object contains the Ai signal 'Value' that should be connected to an
 Ai-channel.

 BaseSensor has four limit, each represented by a CompLimit object. For
 each CompLimit object, specify in the Used-attribute if the limit is
 active of not. If the limit is active, specify also the limit value, and
 possible hysteresis and delay.

 The alarms and alarm outputs can be disabled with the input DisableSup
 in the function object.

 The color of the graphic symbol can be affected externally with the Error
 and Warning inputs of the function object.

 For plc coding the function object BaseSensorFo is used.

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

 For simulation of the sensor value, use the plc object BaseSensorSim.

 Error indication.
 Activated for HighHigh or LowLow alarms, or if the Error
 input of the function object is set.

 Warning indication.
 Activated for High or Low alarms, or if the Warning
 input of the function object is set.

 Shows the input DisableSup in the plc Fo object.

 Trend object for the sensor value.

 Trend object displayed by the trend method. Normally a reference to
 the previous attribute object 'Trend'.

 The plc function object connected to this object.
 This attribute is set when the function object is connected from
 the plc editor by the connect function.

 The simulate plc function object connected to this object.
 This attribute is set when the simulate function object is connected from
 the plc editor by the connect function.
