Unitgroup

This section makes it possible to define a unit and limit values for numerical variables that have been defined in section "Argument types".

The name of the defined argument is entered under "Identifier".

"Engineering unit" describes the unit that is used for calculations on the controller.

"Display unit" is only seen by the user. Conversion between units takes place based on the selected unit system.

Example

A condition is created that should be used for position monitoring. As soon as the position is exceeded, an alarm should be triggered. The position is specified in millimeters or inches depending on which system of units is used. This can be solved as follows:

Creating a numeric argument:

Numeric argument "Position" is created so that the position can be specified with a unit:

configuration_display_arg

Specifying the units:

A unit can be assigned to numerical arguments in section "Display". Argument "Position" is specified under "Identifier". The unit is defined by "unit codes". For more information, see herehere.

Millimeter ("MMT") is used as an engineering unit and metric unit. Inch ("INH") is used for the "Imperial" and "Imperial-US" systems of units:

configuration_display

Creating a condition:

Condition "Level" is created in the next step. Numeric argument "Position" is used. The condition becomes TRUE as soon as variable "Level" is greater than or equal to the specified position.

configuration_display_condition

Creating an action:

As soon as the position has been exceeded, i.e. the condition has been fulfilled, an alarm should be triggered. The following action is created:

configuration_display_action

Testing the function:

Widget "LadderEditor" is used to create the program. For more information about how to configure the widget, see here. The "Level" condition is selected for a contact. Numeric argument "Position" is automatically displayed; this can be specified in millimeters or inches depending on the system of units used.

configuration_display_browser

Coil "Alarm" is then specified in the program. After the program has been saved and started, an alarm is triggered as soon as variable "Level" exceeds the specified "Position".
