Integration of Remote Terminal Units via SINAUT ST7 protocol in PCS 7 TeleControl

  • Entry
  • Associated product(s)
Following you will find a compact configuration guidelines for integrating Remote Terminal Units via SINAUT ST7 protocol in PCS 7 TeleControl. This guidelines provides you a quick, easy introduction to the topic and helps you to implement a simple project independently.

Automation task
Various branches of industry require monitoring and controlling of plants separated by open ground and their processes from a central point. Remote controlled systems are widely used for this purpose. Fast and secure data transfer constitutes the basis for a successful operation of these systems.
Remote Control Systems realize the data transfer between the remote control center and the process-oriented remote terminal units (RTUs) for local automation using special telecontrol protocols.
They manage secure and faultless data transfer via WAN, even for small band widths and poor transmission quality.

This task does not only require short data transmission times, but also efficient protection of the telegrams against:

  • Undetected bit errors
  • Unknown telegram error, resulting from
  • Synchronization errors
  • Undetected data losses
  • Telegram falsification
  • Separation or distortion of connected data

Solution
Via different telecontrol protocols the remote control center in SIMATIC PCS 7 allows controlling and monitoring of widely distributed remote terminal units (RTUs) via serial or Ethernet TCP/IP communication connections.
The most important three telecontrol protocols are DNP3, SINAUT ST7 and IEC 60870-5. Depending on in which region the plant located, a certain standard could be demanded.

Your benefit at a glance
SIMATIC PCS 7 TeleControl combines the automation of central plants and monitoring of decentrally distributed processes in one control center.

  • Plant automation and remote control in a single integrated system
  • Uniform visualization reduces the risk of operating errors
  • Integrated engineering and simple data management
  • Reduced cost of installation, commissioning and maintenance

Validity
This entry was created with SIMATIC PCS 7 V7.1, the procedure is transferable to higher PCS 7 versionen.
