what is control system of MNC?

Question

control system of Multinational company. purchase procedure. transnational rules.

Answer 1

The control of the MNC is the one what we are all seeing how the India was controlled by the America thats enough example for U. Yeah if U R going to purchase then its just the thing of putting the Purchase Order

Answer 2

SatService´s Monitoring & Control System is a comprehensive software-based system providing monitoring and control of any type of satellite ground station and associated baseband equipment.

The system consists of two parts:

* 2HE 19" Industrial PC with Ethernet interface and und seriall interfaces connected to the ground station equipment
* sat-nms IO-Panel 19" 2HE for interfacing to opto coppler input and relay outputs.

The sat-nms M&C Software is seperated into two in Java implemented modules: M&C Server and Client. Both modules are installed on the industrial PC and running under the Linux operating system. The plattform indepented client software can also run on every via TCP/IP connected workstation.


Key Features

* Client Server Software Architecture
* TCP/IP based design
* Server operating under LINUX with full remote administration and support capability
* Clients are pperating system independent
* Unlimited number of clients possible,
* Event/Alarm Log with a lot of filter utilities
* Task- und device oriented user interfaces
* Macro Recording functionality
* Software configurable Interface Device Configuration
* Integrated graphical tool for user interface configuration
* Comparable equipment of different manufacturers has the same "look and feel"

* 2HE 19 Zoll rack-mount Industrial PC
* LAN (TCP/IP) Interface
* Powersupply wide range input voltage 90V to 240V 50/60Hz AC
* CD and ZIP Drive for Backup Capability
* Rack mountable 15" TFT Monitor, Keyboard and Trackball for local control

Interfaces to Satcom equipment

The MNC is able to monitor and control the attached equipment through the following types of interfaces:

* Serial RS232 interface
* Serial RS422/RS485 interface
* Network interface (Ethernet,TCP/IP)
* SNMP interface over network
* Parallel interface for low level devices like alarm contacts or waveguide/coaxial switches via the sat-nms IO-Panel

M&C Server

The M&C server monitors and controls the equipment of a satellite ground station. The monitoring is performed locally without any influence and connection by any Operator Client. The connected equipment is polled and monitored continuously. Typical Alarm flags of the equipment, like summary alarm, lock alarm, etc., thresholds or limits of data quality are detected. The alarm message is stored in the internal M&C database at the M&C server and the client operator is alerted via both a graphical and a audible alarm.

Virtual Device Drivers defines families of Satellite Ground Station Equipment with common user interfaces for operator with multi vendor equipment in the field, e.g. all satellite modems are presented to the operator in the same look and feel. This simplifies the handling because device specific details are hidden from the operator.

Logical Devices are also available like EIRP Adjustment, Data Logging (any parameter which is displayed can be logged to file), Redundancy Switching and Site Diversity Switching. up
sat-nms Drivers

The Universal Device Driver concept reduces the cost for the configuration of new drivers. The user can configure its own drivers without writing software. Parallel to that SatService will always provide the service to adapt new equipment with drivers to the system. Drivers are always the same for M&C and VLC systems.

The Driver Development Kit (DDK) which is an Eclipse-Platform based Integrated Development Environment support the user to configure and test new drivers and protocols. For details please read the data sheet(pdf) . A Reference document about the sat-nms Driver- und Protocol syntax is available here. up
Device Licenses, Configuration changes and Upgrades

The basic sat-nms MNC-0/0 system contains already 5 device licenses which can be used e.g. for devices connected via TCP/IP. Additionally, each MNC system package contains device licenses for every serial interface which is included e.g. the MNC-4/8 system contains 5+4+8=17 licenses to monitor and control 17 units.

With the included configuration tools for the interface setup and the graphical user interface the customer is able to add, remove or change the connected equipment. The customer is also able to add new types of devices from the sat-nms driver library or even configure new drivers by himself.

This flexible approach gives you all possibilities to use the sat-nms M&C system even with changed conditions in the future. Upgrade kits to extend the number of available interfaces are also available. up
M&C Client

The Client Software is the User Interface for the operator of the ground station. The operator accesses the M&C system directly on the M&C Industrial PC or via a arbitrary workstation in the network connected via TCP/IP . The number of clients is not limited.

The platform independend Java Software requires only a Java Virtual Machine on the Client-PC. We have tested the software successfully on Windows 9x/NT4/W2K/XP and of course on Linux PCs.

With the purchase of the sat-nms M&C system you obtain the licences for a unlimited number of clients so that you do not have additional cost.

There are two kinds of user interface available:
mnc task gui

* device oriented user interface
* Task oriented user interface

The Device oriented User Interface provides all parameters of the satellite ground station equipment and a deep insight in the equipment for system engineers. It is part of the delivery and shows every attached device in a block diagram view. The device oriented srceen will mostly be used in stations with a static configuration for monitoring & control and redundancy switching.

The Task Oriented User interface is a customized User Interface, fully configurable and reduces the user interface to the special requirements of the operators. Several task oriented and or device oriented User Interfaces can be used in parallel. SatService will be glad to offers you the configuration regarding you needs, but you are also able to do this on your own with the integrated graphical screen editor. up
Remote Access

The M&C server is completely remote configurable and maintainable. This requires only a TCP/IP connection. Also the Clients requires only a TCP/IP connection to the M&C Server. This could be a already existing network (LAN) or a dialup connection (e.g. PPP).

SatService offers also ISDN and VPN solutions to connect different locations on request. Via these routers SatService can give you remote support if you need it. up
