Technical specifications
a) EDIBON Scada Net System technical specifications
EDIBON SCADA – NET (ESN) System reproduces an integrated model plant (CIM model) which defines
the various levels of communication:
• Management – design level: orientated towards production management, this level requires the
installation of networks, which can handle a large amount of traffic with no restrictions on response
time. Local area networks adapted for this level are based on an Ethernet architecture.
• Factory floor level: factory floors, which are made up of cells, exchange data and can therefore
monitor production. At this level the data rate of the network must be high enough to allow to exchange
large quantities of data. In this case the factory network is based on a Fipway architecture.
• Cell level: each device or group of devices are controlled by an overall control system (PLC).
• Machine or field level: each device includes a group of intelligent sensors, actuators and simple control
systems that communicate at this level. Fieldbuses (FIPIO) are used.

- The Central PLC-Master PLC is part of an integrated model plant that uses X-WAY networks and it can be
perfectly integrated into the CIM model.
- Several networks operating on different levels and on sites which may reach a considerable size, can only
work together and provide total communications if the networks are connected together in hierarchical
(multi-network) architecture.
- The Central PLC-Master PLC provides the connection between two network types, Ethernet and Fipway, by
a common PLC (network node) in a bridge type architecture where the PLC routes messages from one
network to another.
- The elements are:
∗ Ethernet connection. Provides the connection to the Ethernet network that is the communication to the
PCs.
∗ Fipway connection. Provides the connection to the fipway network, that is the communication to the
PLCs. An end of line is connected to one of them, because the PLC are in cascada architecture.
∗ Unitelway connection. This type of connection is necessary to charge the programme and PLC,
including the Central PLC-Master PLC, have a unitelway connection.
∗ Power supply.

5) EDIBON SCADA-NET Software Package (ESN-System) for classroom control and management.
- The ESN-Software (EDIBON SCADA-NET System) is an acquisition and control software developed
entirely by technicians of EDIBON. In its development, we have been taken into account the experience
accumulated in more than 20 years developing teaching equipment.
- The system is prepared to communicate with Electric PLC's, through OFS Software. OFS (OPC Factory
Server) is a multi-PLC data Server that uses the OPC (OLE for Process Control) standard which allows
ESN-Software (data processing application) to access the control system variables in Electric PLCs (Micro
and Premium PLC models).
- In this system, there are different configuration levels that allow the professor to design in the fair measure
the execution of the different practical exercises. The basic level is prepared for the capture and storage of
data that the student will process and will work with later. The medium level allows the student the use of
the graphic tools that allows, in real time, the visualisation of the data experiment. Finally, it has an
advanced level specially designed for the capture configuration, the sensors device calibration and to change
the PLCs parameters. This system is subject to a key provided by EDIBON.
- Compatible with any Windows operating system. Graphic and intuitive simulation of the process in
screen. Equivalent distribution of the elements to the real process. Registration and visualisation of
all the process variables in an automatic way.
- Flexible Control Software, developed with actual windows graphic systems, acting on all process
parameters. Data acquisition and also with PID analogical and digital control and other control
types. Menu for PID and the set point selection required in the whole work range. It provides the
management, processing, comparison and storage of all the data, with a sampling velocity up to
130.000 data per second. Nested loops control system.
- Calibration system, for the student's use of all the sensors that work in the process.
- It allows the registration of the state of the alarms and the graphic representation in real time.
Comparative analysis of the obtained data, after to the process and modification of the conditions,
during the process.
- Open software, allowing to the teacher to modify texts, instructions, etc. Teacher's and student´s
passwords to facilitate the teacher's control on the student, and that it allows the access at different
work levels.
- This software is prepared to be adapted to this particular process, with capacity for doing all the
exercises indicated in the Fluid Friction in Pipes Unit.
