vista-automation-logo is a powerful and clearly-structured
alarm, control and monitoring system!

Processing Level

The system is organized in a cellular structure.
Each cell consists of a local display panel (DAD/RCP/PCP), a field computer (SMU) suitable for sea going vessels, and I/O nodes. The SMU forms the core of the cell that contains all logical links and parameters.

All SMU’s in the system are linked with each other. The tasks of the automation system can be optimally adapted to the various requirements of the operator. Depending on the measuring points to be processed, the system can consist of one or more autonomous cells. Each cell takes on its own tasks, or a task is distributed to several cells.

Process Level

The inputs and outputs are processed by I/O nodes. These components process and make all on-board electrical measuring signals available. They have an RS-485 bus connection to the SMU. They can be connected at nearly any distance from their SMU directly to the aggregate to be monitored or controlled (decentralized system), or they can be installed in the control room (central system).

Features Of The I/O Nodes

  • earth leakage and external voltage detection
  • galvanic isolation from power supply

Comfort Level

The visualization system provides a graphic representation of measured values, alarms, lists and acknowledgment of alarms and the operation of aggregates such as pumps and valves. A user-friendly interface reliably guides the user through the system.

Duty Alarm System

The extension alarm system (XAS) enables unmanned engine room operation. It works independently of the visualization system and notifies the engineer on duty in case of alarms. The XAS obtains its information from the SMU’s and represents them on display panels, printers, luminous call systems and other alarm devices. It consists of several panels for wheelhouse, engine control room, mess room, accommodations and the alarm and journal printer. Each XAS panel displays the alarm group and a list of the alarms. An alarm, coming up, is signaled on the panel of the engineer on duty and in the engine control room only and can solely be acknowledged at these two panels. Additionally, there is the possibility to indicate the fire alarm, the common engineer call and the selective call. The Extension Alarm System is connected via the redundant RS-485-Bus system.

Interfaces To All Kind Of External Systems

The reliability of operation in critical situations is an important feature of VISTA® AUTOMATION. Cable redundancy up to the workstation ensures the reliability of the alarms and control of the aggregates.
The redundancy of the SMU ensures failure-free operation. The SMU can be exchanged during operation (cold redundancy). The server redundancy prevents data loss in the visualization system if a workstation should fail.
