Telecontrol and monitoring of remote sites or mobile devices is what TO-PASS from Wago does. Using the Web connector, the telecontrol modules can now be integrated to a greater extent into the control center. The heart of this Web connector is a special function block for the CoDeSys development topology. This function block registers the HTTP queries from the telecontrol modules, saves the process image in a global variable list and transmits a corresponding acknowledgement. The received data can then be processed by the supplier's I/O system as needed. Economical, bidirectional transmission using the Web connector is also used by network service providers to comply with the renewable energy act: The power reduction required by this act based on IEC 60870-5-104 is achieved by technical means by private power producers using the telecontrol modules. From a fault message via process and position data acquisition up to a fully functional PLC: The product family is made up of modular telecontrol components, which enable independent monitoring of remote objects, at any time and anywhere in the world.
