The educational systemInteractive Highway Network is based on a real-world system for monitoring and managing highways.
The real Agora system is used to manage and organizeroad traffic safety. It informs and guides motorists by broadcasting information and traffic conditions.
The teaching system uses the architecture of the 3-layer hierarchical network, field bus (Modbus) and computer bus (Ethernet, Internet). It integrates the "business" server (Modbus master) communicating with two virtual operating parts (weather station and display panel) and the "TCP/IP" server connected to the client workstations (TCP/IP).
Technical solutions addressed:
RS232 / RS485 field bus with converters
Ethernet / Internet computer bus
Master / Slave communication
Client/server communication
Virtual operating parts: weather station and display panel
The educational sequences provided implement the skills in the certification reference framework, taking into account the tasks in the professional activities reference framework.
All practical work is entered into C Pro STI
Bac Pro CIEL practical work - RS232 - Level 1 Acquisition:
Context description / Professional scenario: The technician must analyze the operation of an RS232 connection in order to understand the principle of data exchange on an industrial bus.
Professional issue: You will be asked to configure two PCs to analyze data exchange using the simulator and identify a probable malfunction in the link.
Context description / Professional scenario: The technician must analyze the operation of an RS232 connection in order to understand the principle of data exchange on an industrial bus.
Professional issue: You will be asked to configure two PCs to analyze data exchange using the simulator, intercept frames using an oscilloscope, ensure the conformity of the results obtained, and identify a probable malfunction in the link.
Context description / Professional scenario: The technician must analyze the operation of an RS485 bus, understand the benefits of differential transmission, and grasp the principle of data exchange on an industrial bus.
Professional issue: You will be asked to configure three PCs to analyze data exchange using the simulator, intercept frames using an oscilloscope, ensure the conformity of the results obtained, and analyze the frame coding.
Context description / Professional scenario: The technician must analyze the operation of an RS485 bus, analyze and develop MODBUS frames to understand the principle of data exchange on an industrial bus.
Professional issue: You will be asked to configure three PCs to analyze data exchange on an industrial bus using the simulator, analyze the MODBUS protocol, develop frames to simulate exchanges on the RS485 bus, and view the results obtained.
Context description / Professional scenario: The technician must install the highway system and ensure that the supervision system is working.
Professional issue: You will be asked to configure four PCs to analyze data exchanges on an industrial bus using the simulator, configure and exchange data between a client and a TCP-IP server, test and validate the operation of the supervision system, and view the results obtained.
Context description / Professional scenario: The technician must install the highway system and ensure that the supervision system is working properly. They must familiarize themselves with network test commands and the "Wireshark" frame analysis software in order to maintain a TCP-IP network.
Professional issue: You will be asked to configure four PCs to set up and exchange data between a client and a TCP-IP server, view TCP-IP frames using Wireshark software, use basic network maintenance commands with the Windows CMD command editor, test and validate the operation of the monitoring system, and view the results obtained.
