1.1
What is JavaHMI
JavaHMI is an Open
Source Java™ API for developing human machine
interfaces. It is based
on a observable/event driven control pattern.
JavaHMI's graphical components can be programmatically
attached to remote controller resources.
The
control objects are event driven, in that they fire
change events when the resource changes state. An
operating range can be defined for the control
objects. If the operating value goes outside this
range the object fires an alarm object. This makes
data/alarm logging extremely simple.
JavaHMI is not a manufacturer specific API. This
package is extremely extendable. In addition to
machine control components, this API could be
integrated with system resources like memory or hard
disk space very easily.
