Engage IPTube models facilitate SCADA protection

Evolved models of Engage Communication's circuit emulation IPTube product line facilitate critical supervisory control and data acquisition (SCADA) infrastructure protection. IPTube seamlessly connects existing remote terminal units (RTUs) and control centre equipment to an advanced IP infrastructure, provides diverse and redundant transport paths, includes critical equipment redundancy and integrates the instantaneous detection of both the main and back-up SCADA control centres.

Both chassis-based central site and space efficient remote Engage IPTube units transparently convert a variety of existing SCADA communication protocol and link types into IP packets for transport between control centres and RTUs. The conversion of SCADA information into packets emulates the behaviour of telecom circuits to ensure SCADA communication protocols such as Modbus�RTU,�RP-570,�Profibus�and Conitel are delivered without error, and the precise timing between polling requests and responses is maintained.

IPTube is a unique solution that enables existing control centre and RTU equipment to connect to an IP transport network while delivering the necessary redundancy and diversity to implement a back-up control centre infrastructure meeting North American Electric Reliability Corporation (NERC) standards. NERC, with approval from Federal Energy Regulatory Commission, established the need for back-up control centres with redundant and diverse connectivity.

The Engage solution accelerates deployment, reduces complexity, and saves time and money for utilities considering implementing NERC reliability standards.

The advantages of IP transport between control centres and RTUs includes lower transport costs of Ethernet packet networks and highly resilient equipment and packet routing.
