The Ardax Model SCS2000 Supervisory & Control System Network Manager is a full-featured, yet cost-effective alarm supervisory & remote control system with an intuitive graphical interface. The system generally consists of one Master Computer Terminal Unit (MCTU) at the monitoring headquarters and a Flex Terminal Unit (FTU) or Remote Terminal Unit (RTU) at each of remotely located sites.

By installing one or more additional Slave Computer Terminal Units (SCTU), the MCTU can be viewed and operated from remote locations over the LAN on a permanent basis. Also, with the use of Ardax's remote access software, authorized users can access the MCTU via the Public Switched Telephone Network (PSTN) to view the status of the network, acknowledge alarms or perform remote control operations.

For enhanced security, this system offers three-level password security (alarm acknowledgment, remote control operation and system configuration) and log-on passwords for multiple operators with identifications (i.e. user names).

SNMP Protocol is used to communicate with the SCTU and other computers, such as HP OpenView® and IP format for the optional multi-port Network Interface & Protocol Converter Unit (NIPCU). The NIPCU on its serial port side communications with a protocol similar to SCADA systems with checksum error correction.
The system supports from 1 to 999 Addresses per port, with blank, or A to G letter suffixes per address. Each port can be labeled with a distinct network name or number.



The Station Summary Screen displays summary alarms and station polling status for all stations in the network. The light under ALM displays a summary of all the alarm points within a station. The light under ANA displays a summary of the alarm state of all analog points within a station. The light under RLY displays a summary of the relay state within a station. Using filter buttons in the tool bar, the summary screen can be made to display all stations, only polling stations, or only stations in alarm.


The Mapping Screens are user defined and created or factory created from user information. The screens as shown here represent a high level view (left) with lights summarizing system details. Clicking on a light will cause the next level to be displayed ( middle) with a greater level of detail. Again the lights may represent specific equipment directly, or by clicking on a light further details may be displayed (right) taking the user directly to the equipment in alarm. If a light were linked to specific station then clicking on that light would display the Station Summary Screen with that station highlighted.


The Alarm Screen lists the alarm detail for a specific station or piece of equipment, such as a Digital Radio. The alarm state of each point is displayed, along with the names, comments, and ACO state. Each alarm point is either a Status, Minor, or Major Level. Colors are used to represent the state and level of each alarm point. Green is either a Minor or Major Normal State. Yellow is a Minor Alarm State. Red is a Major Alarm State. Blue is a On Status State. In addition to steady lights the alarm lights will initially flash when they first occur and continue to flash until the operator acknowledges them.
