Ethernet and Profibus networks of PLCs

Maqueta 4 Tanques

The LRA-Ule (Remote Laboratory of Automatic Control at the University of León) provides a tool for configuration and programming of PLCs through the Internet. The use of this tool will allow authorized users to check the correct operation of their programs in a real PLC, not a simulated one. The control system is linked to the industrial process models if the user has the appropriate privileges.

SUPPRESS research group © from University of León designed and developed this system.


Available control systems are: PLCs Premium TSX P57 from Schneider, PLC’S Simatic S7 314 2DP from Siemens, PLC’S XC-CPU 201 from Moeller and DCS SNAP LCM4 from Opto22.

These control systems are linked via OPC (Ole for Process Control) with the data acquisition system of the 4 tanks and 4 variables models.
