基于 S7-1500 的模块化 RTU

Telecontrol substation using the example of an RTU based on the SIMATIC S7-1500 Advanced Controller

High-performance RTUs for extensive control tasks

RTUs based on the SIMATIC S7-1500 Advanced Controller impress with highest performance and flexibility. Telecontrol stations (RTUs) are connected to a Telecontrol control center via the TIM 1531 IRC Telecontrol interface module using Telecontrol protocol (SINAUT ST7, DNP3 or IEC 60870-5). This allows the complete product range of the S7-1500 to also be used for setting up substations in the Telecontrol environment.

RTUs based on SIMATIC S7-1500 are suitable, in particular, for complex and extensive Telecontrol applications – such as in widely dispersed sewage systems or drinking water supplies, district heating systems, as well as in oil extraction and gas supply, power distribution and traffic engineering.

The TIM 1531 IRC can also be used both as node and as master station in Telecontrol systems.

• Modular and flexible
  The SIMATIC S7-1500 offers the most comprehensive range of varying CPU types – from standard and fail-safe CPUs, compact CPUs to redundant and high-availability CPUs. In addition, a wide range of I/O modules and technology modules are available.
• Various Telecontrol protocols
  Connection to all types of Telecontrol control centers with IEC 60870-5-104/101, DNP3 or SINAUT ST7.
• Secure communication
  Secured data traffic between the Telecontrol control center and the process stations in the field (RTUs) using encryption algorithms.
• High availability
  Path redundancy offers high availability even when the primary connection fails. Through support of the S7-1500 R/H CPUs, redundant substations can also be realized and connected to the Telecontrol control center.
• Simple configuration
  Standard engineering with TIA Portal STEP 7 enables easy and fast programming, networking and commissioning.
