What is Telecontrol Technology?
”Telecontrol“ describes the remote control and monitoring of off-site objects. By means of signal-converting procedures, process data can be transmitted and received from one or more locations.
In the 1950s, telecontrol technology was still a “human.” Switching commands, e.g., in energy technology, were transmitted by analog telephone and personnel at a substation then performed by hand. The “feedback” was then returned by a call. Nowadays, the data is traditionally obtained from a substation (e.g., PLC) that transforms it and transmits it via various transmission media (GSM, radio or wired) to the central station or control system.
Various data protocols transmit this sometimes very sensitive process data. For example, the IEC 60870-5-101, IEC 60870-5-103, IEC 60870-5-104, IEC 61850 and DNP 3.0 protocols have established themselves as standards for supply technology in particular.
System requirements are high. In addition to a rugged design, the probability of failure and special measures for security and data protection are the main focuses.
