M-JVIS, M-JSYS Java Libraries

M-JVIS and M-JSYS are libraries for creation of visualizations

under Java that can be used platform-independently on

Java-capable devices. The components are based on Java

version 1.1.8.

M-JVIS consists of the following packets:

● M-JVIS/DACC

● M-JVIS/UTIL

● M-JVIS/GUI

The packets are divided into two types of classes:

● Configuration classes that are implemented in the form

of beans

● Runtime classes that permit a dynamic configuration

and during runtime handle the management or presen

tation of the data

The configurations of all objects are stored in XML files.

their values (DACC = Data Access).

M-JVIS/DACC consists of the following components:

● Process variable management

● Recipe management

● Unit switchover

● Communication interface

M-JVIS/UTIL

The M-JVIS/UTIL packet consists of the following compo

nents:

● Language management / language switchover

● Protocols
