V-MAC Reliant: Always-On-Duty

System Overview:

DataStar's V-MAC Reliant is a networked (V-MAC DataBus) Monitoring, Alarm and Control system with up to 36 - 24 input Multiplexed Data Gathering panels and 16 - 4 input RPM/Frequency nodes reporting to 4 networked (V-MAC DataBus) Control Group panels. Each Control Group panel reports to the Master DMU and is capable of standalone operation. Each of the channels on the system is fully configurable, and will be customized to the vessel's specific requirements and delivered turnkey.

Typically input is acquired from a hardwired sensor. V-MAC can also receive input from ModBus devices, CanBus devices, Cobra devices, electronic engines and NMEA 0183.

 

Each input optionally creates reports for (a) Hour Logging and (b) Trend Plot analysis. The entire system can be saved to file as a (c) SnapShot overview. Settings for a, b and c are from 10 seconds to 24-hour periods depending on vessel requirements. Settings are pass code protected.

Output is achieved with 4 form C relays and 3 fixed DC voltage on each MUX panel plus 1 fixed DC voltage and 1 synthesized audio on each Keypad Node. Also ModBus and CanBus variable outputs for automation.

 

V-MAC may be configured to serve a wide range of applications. In its simplest form, V-MAC is ideal as an affordable integrated alarm system for home, office, yachts and work boats. Yet the V-MAC Reliant is fully expandable to supervise a wide range of operating systems on the largest commercial, industrial, military and marine applications.

Functional Overview:

Input:

Sensors: Sensors throughout the system are connected to DataStar Compatible Data Acquisition Panels. These "MUX panels" electrically condition the incoming feeds from each sensor and convert the information, whether analog or digital, to a digital code. Digital signals are then combined (multiplexed) into encoded message packets, and sent via the V-MAC DataBus to the V-MAC Main Control panel for processing.

A variety of Input types are handled by Line Conditioning Modules. These plug-in LC Modules provide the first stage of signal processing and allow the V-MAC Reliant to accept data from virtually any sensor or data source. 

Seven standard LCM designs will accommodate data from many different sensor types:

1. Digital Switches (door contacts and switches etc.)
2. 4-20mA
3. 0-16,  0-32 and 0-60 DC Voltage
4. AC Voltage Transformers and Current Transformers
5. Variable Resistance
6. RTD (Resistance Temperature Device)
7. Thermistor
8. Custom...

RPM & Frequency: The DataStar RPM/ Frequency Node can measure frequency input such as engine speed and AC generator frequency with a high degree of accuracy.

Interface: 

DataTerm G55: Warnings, alarms, and other messages are displayed on a back-lit LCD screen. Multicolored LEDs provide system information and indicate the status of certain onboard sensors. The keypad is also used to acknowledge alarms, program the V-MAC system, and view the log.

Data Management Unit (DMU - Marine), Machine Management Unit (HMU - Industrial, Commercial and Military) and Home Management Unit (HMU - Residential version): The fully-equipped V-MAC Reliant includes multiple networked Management Units running Visual V-MAC software. In addition to alerting the operator to alarms and warning messages Visual V-MAC displays information on all monitored systems.

Visual V-MAC is completely User modifiable so gauges and controls can be added at any time. Once your design changes have been made the design can be locked with a pass code.
