Cooling
Figure 5 - sample graphic components from the Cooling folder
The Cooling folder contains dynamic images representing air coolers. Due to the features
described in section 2, the graphic components in the folder must be arranged in the correct
order in the PX file. This principle is the same as for the static images described in the
chapter 2.1.
2.3.1
Alarm components
Components with the suffix "alarm" in the name are dedicated to bind Boolean variables
signalling an alarm or failure. Graphics representing the alarm status of the device have been
added to these objects. The component has one control value (Value Binding), which affects
the Visibility property. The value of the true component of the Boolean type causes the
graphics to be shown, while false causes the graphics to be hidden.
2.3.2
On/Off components
Components with the suffix "off-on" in the name are dedicated to binding Boolean variables
signalling operation or switching on. Graphics representing the status of switch-off and
switch-on of a given device have been added to these objects. The component has two
control values (Value Binding). The first one affects the switching between switching off
graphics (false value) and operation (true value) of the device. The second value affects the
Visibility property, where false causes the graphics to be shown, while true causes the
graphics to be hidden (same variable as for the alarm component above).
