An introduction to Proview
ProView is an Open Source Process Control System which is commonly programmed graphically. This graphical interface provides a very intuitive, easy and fast-programming. It can also be programmed with high level languages such as C, C++, Java or FORTRAN. It is the first Open Source Process Control System that can work with oriented objects. So it is directly programmed with simple function blocks and simple signals. A typical Proview system consists of one process control system and one or more operator stations. It is easy to configure one operating station to become the HMI-system of several control systems.
Possible communication protocols are Ethernet(UDP and TCP) and Serial(RS232, RS485 and I2C). There are many ways to communicate a PLC with this software and get the results in a really intuitive way.
This photo shows a real implementation of the potential of this Process Control System:
In this example it is shown a complete visualization of an hydraulics installation. It shows the level of the tanks, temperatures, graphs…
It is more intuitive to see an interface like the one in the photo than see lot of parameters just represented as numbers.
An example on the programming tool for ProView would be the following one:
This example shows a Processing of sensors+motors. As it is shown it can be configured with “Wait”, Timers… It also makes arithmetical functions to combine signals… There are many tools to program all kind of processes in a really precise way.
