Components for secure process interface and smart grids:

Reliable connection of substations to a superior control system

Telecontrol systems for the secure process interfacing

In the area of energy management high available, scalable and secure telecontrol systems are important for the process interfacing. Multiple locations with different interfaces and telecontrol protocols need to be connected to the control centers.

PSI GridConnect network components meet these demands.

  • redundant installations and modular interface extension
  • extensive security features complying to the high security standards for data networks (NERC CIP)
  • preprocessing of telecontrol protocols to unburden the system

Scalable Concept for Network Components

Fitting to your specific scenario

Telecontrol Gateway 3G-88
Telecontrol Gateway 3G-8 + 2 Slaves24
Telecontrol Gateway XS-Master + 8 Slaves64
Telecontrol Gateway VM1024

Select from a wide range of possibilities:

  • Connect single substations to a control system.
  • Choose a master and slave solution which can be extended on demand.
  • Use virtual devices to have the highest flexibility fo the extension of existing installations.

Example 1: Up to 24 telecontrol interfaces

1 Telecontrol Gateway 3G-8 + 2 Telecontrol Gateway 3G-SU as slave devices

Example 2: Up to 64 telecontrol interfaces

1 Telecontrol Gateway XS-Master + 8 Telecontrol Gateway 3G-SU as slave devices


How to guarantee Continuous Monitoring of Energy Supply

Reliability through high available systems

For high available connections connect remote terminal units redundantly to the control center. If one connection fails, the backup connection takes over the communication.

How to profit from the redundancy functions of our network components:

  • redundant interfaces for the connection of RTUs
  • bonding interfaces for the connection to the control center
  • a redundant power supply


Telecontrol Protocols

For the transmission of process data between substations and the control center, special telecontrol protocols are used.

As protcol converter our products support numerous producer dependent and standardized telecontrol protocols including IEC 60870-5-104 and IEC 60870-5-101. This allows the connection of existing substations to modern control systems.

Additional telecontrol protocols with PDM or PCM-UART encoding can be easily integrated.
