The configuration - the RTA as open architecture
And ABB chose RTA to develop this control console. Once again
ABB needed something like RTA - a flexible tool, based on well-know
industrial standards, which allows doing projects like this in
a fast and flexible way.
The whole logistic system can be controlled and managed by the
RD-Station. Using screens like this on the left you can check
the status of every axe of the reel star in the autopaster, see
the paper type and how much paper is left for the running printing
order and how much rolls are planned for a certain / next order.
You are also able to send manual requests for additional rolls,
manage the remaining web-paper on the rolls back to the stock
or declare it as waste.
The base system RTA combines real-time aspects with the usage
of a relational database system like Oracle. The real-time communication
needs with three other system units (the control system of the
roller conveyor, the control system of the reel star and the production
planning system - three different suppliers) and on the other
hand the need for an open architecture were the main reasons why
RTA was chosen.
Another major reason was the fact that RTA supports different
programming languages, allowing the programmers to decide which
language they prefer for implementing a project. But RTA also
provides its own programming language, especially designed for
rapid implementation of distributed, redundant, real-time applications.
This language takes into consideration that the real-time database
(RtDB), a major component of RTA, is an active database system
and hence this language supports ECA rules (Event Condition Action
rules). And last but not least the fact that RTA has an open architecture
and allows for easy integration of third party products played
an important role in the decision for RTA.
