The core of a Hyper SCADA Server is the Hyper Server Module (HSM), which includes a CPU, two voice-grade modems, and the necessary network interface hardware. In addition to the HSM, each Hyper Server Unit includes a Network Switch Module, Power Supply Module (PSM), backup battery, and surge suppressors. This combination of components provides a complete SCADA server with integral UPS function. Various Network Interface Modules are available to meet job-specific network requirements.

The Hyper Server Module (HSM) is a Pentium-class computer housed on a DFS module card. The HSM uses the Linux operating system and runs HyperTAC II, the software used to configure, control, and monitor all aspects of a water/wastewater system. User interfaces to the HSM are through a network via a standard Web browser.

The HSM communicates with the system’s RTUs via a network interface. The HSM can communicate with up to 250 Network RTUs per NIM driver, and it is capable of communicating with 100 fully populated Network (FIM-based) RTUs with a total system poll rate of less than five seconds. The HSM can also simultaneously poll multiple DFS (radio) and/or Modbus RTUs through the network using Fiber Interface Modules (FIMs).

Two voice-grade modems, which double as data terminal modems, enable voice alarm call-out, telemetry control and general status inquiries by phone, and remote computer access via dial-up connection.

Local voice alarm annunciation is available for use in a sound system (PA system, amplified speakers, or an amplifier plus speaker system). In addition, alarm horn and alarm light outputs are provided to accommodate large facilities where alarm announcements aren’t always within earshot of personnel.

Data backup for a non-redundant Hyper SCADA Server is accomplished through the network by defining a client-computer backup location. In redundant mode, data redundancy is managed by the system as it continually copies data from the primary HSM to the backup HSM (mirror imaging the primary). A redundant Hyper SCADA Server can be configured to backup to a designated client PC as well.

Other features of the HSM are a manual CPU shutdown button, status LEDs that indicate CPU activity and system status, and several configuration straps at the card edge that provide system-level configuration options.

Power and Voltage Monitoring is accomplished through the HSM’s onboard 8051 processor. The 8051 processor constantly monitors the Hyper SCADA Server’s AC Power and DC Voltage. Parallel port bits on the HSM provide this data to the HyperTAC II SCADA Software external point database. This information is stored in an accessible database and can be monitored via custom screens and alarms. If AC power is removed from the Hyper SCADA Server (black/brown out), the backup battery begins providing power to the server and an alarm will be generated. If AC power is not restored and battery voltage drops below 11.8 volts, the 8051 processor will provide a shut down signal that prompts HyperTAC II to begin a safe shutdown of the HSM’s operating system. When shutdown of the OS is finished, the 8051 processor will shutdown the HSM’s microprocessor and hard drive. An alarm can be configured for notification prior to shutdown due to low battery voltage. The 8051 processor will continue to monitor voltage after shutdown is complete. When the battery voltage reaches 12.3 volts (as a result of AC power being restored and the battery being recharged), the 8051 processor restarts the HSM’s microprocessor and hard drive.
