Remote control of S7-1200 RTU with PCS 7 TeleControl (IEC protocol)

  • Entry
  • Associated product(s)
Technological plants can stretch over large expanses, especially in the water and waste water sectors. Storm water tanks may be connected to a central sewage plant through a channel system spanning kilometers. Remote control systems such as PCS 7 TeleControl integrate such remote terminal units directly into the high-level control system.

In this application example, a storm water tank is controlled by an S7-1200 controller and integrated into the high-level control system using PCS 7 TeleControl. The communication between PCS 7 TeleControl and the remote terminal unit is based on the IEC 60870-5-104 protocol.
