SCADA for primary substations and small networks



Netcon 3000 Compact is an advanced single-user, one-computer SCADA that can be combined with the ­Netcon 500 systems of primary substations or used as the main SCADA system for small distribution networks.

Netcon 3000 Compact has all you need for the network management or local supervision of a substation: alarm and event history, current ­switching state of the network/sub­station as well as measurements and trends, combined with an advanced report functionality. The user interface is highly configurable, as in modern large SCADA systems.

It can be delivered, for example, on a fanless, 24 VDC fed industrial PC for installation in a cabinet at a primary substation, or on a desktop PC with two 43″ monitors for a small control room installation.



he Netcon GW502-iM is a compactly packaged gateway and protocol converter built specifically for harsh substation environments. A standalone device without a rack, it can easily be duplicated to form a redundant, fault-tolerant pair.

Integrated cyber security

The Netcon GW502-iM avoids so-called man in the middle attacks because it does not rely on external security devices; it has integrated cyber security:

  • Support for multiple VPN connections
  • Firewalls
  • 256-bit AES encryption
  • No OPC – no Windows vulnerabilities
  • Hardened against remote access toolkit (RAT) attacks.


Modular substation gateway and RTU


The Netcon 500 is a versatile, standards-based remote terminal unit and substation gateway. Hardware modularity and a rich set of software features make the Netcon 500 a very flexible solution, protecting your investments long into the future and lowering the total cost of ownership.

Built into a rack containing slots for 3–14 removable card modules, the Netcon 500 system has two functional main parts:

  • The GW502 is the master card and the main processing unit of the Netcon 500. It handles the communications, including protocol conversion, and implements the cyber security. It also has provisions for redundancy (see below).
  • The RTU part consists of the required number of digital input (DI64), digital output (DO32), analog input (AI16) or combined input/output (IO64) cards providing the conventional process interfaces for individually wired IO.
