6.2 Analog outputs AO1, AO2
The PR200-230(24).2 has two analog outputs 4-20 mA, the PR200-230(24).4 has two
analog outputs 0-10 V.
Assign to the output the value of type REAL32 within the range 0…1 to control it.
When the value of 0.5 is applied to the output 4-20 mA, the output current will be 12 mA.
When the value of 0.5 is applied to the output 0-10 V, the output voltage will be 5 V.
6.3 Display elements
Different display elements can be created in the application. To switch between two display
elements a jump condition has to be created. Jump condition can be an event of a function
button or of a variable. For further details about display elements and jump conditions see
‘akYtec ALP Help’.
See section 5.1 ‘Menu navigation’ for display navigation.
When assigning а jump condition to the function button, don't forget that the user function will
have a higher priority than the system function.
Example:
If the and buttons are used as a jump condition for a certain display, it will be
impossible to use them to scroll the lines inside this display.
6.4 Auto Precision
Auto Precision function enables to display a REAL variable most precisely for the set number
of reserved characters. To use the option select a display element with an associated
variable of REAL type. Select ‘AUTO’ for the parameter ‘Decimal digits’ in the Property Box.
Example:
To display the variable VAR1 are 4 digits with Auto Precision reserved. The value of
1.546745 will be displayed as 1.547 (rounded). When the value got changed to 110.478696,
it will be displayed as 110.5.
