In subsequent chapters these techniques will be consequently used in the described examples 1 1 Suffix Notation of Variable Names A well designed object for monitoring the process variable status may be copied and switched to monitoring other variable by changing just a single property The first of the mechanisms facilitating such a structure is the Main variable property and suffix notation of variable names Case 1 State Properties primary group Text VarStringValue V1 Color Variable V1 gt 50 Red Black Case 2 Basic Properties Main Variable State Properties primary group Oooo T Te er Pp olor Variable gt 50 Red Black These fragments of Text object parameterization function the same way In the first example the variable name is used twice Making a copy and changing variable would require manual edition of the two properties In the second case the variable name is used only once Using the main variable allows using Variable parameterless function and short notation indicating on the reference to the formatted value of the main variable Copying of the object is very simple moreover also the Group replacement of variables editor function may be used Basic Properties Main Variable Control Variable Control State Properties primary group C a m S VarStringValue Value Another example demonstrates the use of suffix notation based on the main variable name The symbol used in the context of t

6. 4 states which controls the exceeding of 4 limits In the state expressions the main variable value is compared with the limit variable value Variable names as _lolo are the suffix notation in which the represents the main variable name Object dependency of variable names is minimal switching the object to monitoring other variable requires only change of the main variable name Each of the states has its own definition of the Color property The value defined for active state will be used to display If there is more than one active state then the value from the state with higher number will be taken Therefore the sequence of defining the states is essential The state _ olo must be defined after the state _ o and the state __ hihi must be defined after the state _ hi 18 2 3 2 Application of Variable Attributes The following example assumes that the limit values are stored in the attributes of variable definition database Variant B asic Properties Main Variable VAO01 tate Properties primary state Color Black tate Properties state no 1 State Condition _____ F Variable lt Attribute LimitLo Aqua Ble o bState Condition Variable gt Attribute LimitHi Color Red o State Condition Variable lt Attribute LimitHiHi Coor S eow S O The state conditions compare the variable value with the value of the specific limit loaded from a database The limit values must be stored
7. In the example if the value of main variable exceeds 50 state definitions of the Color and Font Style properties will have priority over definitions of the primary state As a result there will be obtained the effect as in option B but without unnecessary iteration of condition and conditional expressions 16 2 3 Using Warning Limits for the Variable Value Another common problem is the need to signalling the alarm limit exceeding The alarm limit values of measurement are sometimes stored in the other process variables They can also be stored in the variable definition database 17 Asix Evo 2 3 1 The Use of Suffix Notation In the following example it is assumed that the limits are stored in variables Where the following naming convention is maintained variable names of the limits are created by adding suffixes _ olo _lo _hi _hihi to the name of the measurement variable Variant A Basic Properties Main Variable A001 tate Properties primary state Pret Plo Black S O tate Properties state number 1 si State Condition EVarriable lt Variable _lo Color tate Properties state number 2 tate Condition _ EVarriable lt Variable _lolo Po Color O tate Properties state no 3 State Condition _ EVarriable gt Variable _hi Color Red State Properties state no 4 tate Condition Variable lt Variable hihi Color ellow There were created

State Selectable should be set to True The properties State Value and State BitWask determine how are the controls executed An undefined mask means the direct control of the state value A defined mask means bit controls In the example shown the state no 1 is the change of the fourth bit of the controlled variable to 1 the state no 2 means sending the value of 4 and the state no 3 is a fourth bit change to the value of 0 An appearance of the state list colours and font is parametrised in the Stations Settings panel in the Settings tab of the States Menu Settings frame A similar functionality may be achieved by connecting a context menu to an object See also 7 2 Connecting Context Menu to Object 84 12 Using Sliders in Bar Class Objects The main task of the Bar class objects is displaying the process variables values in the form of bars horizontal or vertical They may also be used as static objects for displaying a numerical scale on a diagram This section deals with the rules of using sliders built in the Bar class object 85 Asix Evo 12 1 Using Slider to Control Set Point Values In this application the bar is used to show the current setting value and simultaneously it allows changing the value using a slider Basic Properties lActive True Main Variable SliderSet Control Variable C Minimum Control Value SteeringRangeFrom __ _ MaximumControl Vale SteeringRangeTO _
10. The delayed control mode is activated by setting the Immediate Control property to the False value This mode is used in order to avoid coincidental initiation of operation or when the entire group of control operations is to be executed simultaneously The parameterization of the delayed control operations consists of two elements indication of control operation execution pending and initiation of data transfer operation The indication of the pending state is based on the HasWaitingControl function The object which waits for a send signal should modify its properties determining its appearance tate Properties primary state po fext CU nrecognised state Color FHasWaitingControl Red Black In this example the Text object change a colour in the waiting mode Here the conditional expression was used This is the simplest form but it can be only used if the object has no other states changing the colour property It is also inconvenient if there is a need to change more than one property State Properties state x btate Condition FHasWaitingControl Oooo Coor vam OE It is easier to use the additional state with the HasWaitngControl condition This state must be set as the last state of the object or at least after all the states modifying the same properties Executing pending control operations is initiated with the SendControls action Depending on the action parameter used the button or other object executi
