TECNICAL CATALOGUE (V1.1)

OVERVIEW

Producers of hardware use different - internal communication protocols for communication between Hardware. MEDICOP use CAN-BUS protocol called MEDICAN. Users want to connect all hardware to one Software – Building management system. That is the reason that producers of hardware use different options to transfer internal protocol to standard protocol. One of them is OPC – server.

Also Medicop choose this option. Reasons for that are:

REASONS

Easy to use.

Flexible and compatible according to the manufacturer.

Offers high level of functionality.

The development of drivers is no longer a problem for software programmers; this is now a care just for hardware manufacturers.

There is no need for software developers to develop new drivers right away when there is a new version of hardware equipment on the market.

Customers have more available hardware and software manufacturers which is compatible, so they can form their own automated system.

OVERVIEW

OPC or OLE for process control (OLE- Object linking and embedding) is a international industrial standard, developed by the leading Hardware and Software manufactures in cooperation with Microsoft. OPC is based on Microsoft`s OLE/COM/DCOM technology and represents an mutual communication interface between different devices for controlling and custody of tehnological processes. It is a registered mark from a voluntarily international organisation – OPC Foundation, which combines more than 250 leading companies. Some of the biggest: Honeywell, Fischer- Rosemount, Siemens, Wonderware, Intellution, also Microsoft... OPC drow the line between Hardware and Software equipment and developed a standard, equal for all devices. Costumers can now form systems with equipment from different manufacturers and automate them to the highest integration level. The only requirement is that they are OPC compatible. The main objective is to prevent software being depended on the hardware from different manufacturers.

Because of fast industrial development it was necessary to standardize OPC, which is a a time consuming and continuante work, especially Continuous improvement procedure. Till now, the organisation has released more specifications about OPC like OPC standard 1.0, 1.0 with time stamp, 2.0 and OPC XML.

OPC server

An OPC Server is a software application that acts as an API (Application Programming Interface) or protocol converter. An OPC Server will connect to a device such as a PLC, DCS, RTU, or a data source such as a database or User interface, and translate the data into a standard-based OPC format. OPC compliant applications such as an HMI (Human Machine Interface), historian, spreadsheet, trending application, etc can connect to the OPC Server and use it to read and write device data. An OPC Server is analogous to the role a printer driver plays to enable a computer to communicate with an ink jet printer.

OPC client

OPC client is provided by the software manufacturer of SCADA control system. The OPC client must be configured to access to data on OPC platform that is provided by the OPC server and send it back.

GSS SOFTWARE Gss (Gas suppervision system) is a software, developed to display data from Medicop Hardware, which are connected with CAN/BUS protokol called Medican. Software GSS is designed as OPC client and is comunicate directly with OPC server. GSS provide realtime data access and alarm/events from all Harware (Manifolds, Plants, Control closing boxes,…)

The application is designed as a standard browser – see picture below:

POS.

DESCRIPTION

1

First window show us the list of installed gas manifolds with eventual alarm copies and plants for air and vacuum.

2

Second window show us list of buildings with floors in which control closing boxes with eventual alarm copies and stabilizers are installed.

3

The middle window shows detailed view for plant, stabilizer or control closing box that we choose in left window (pressure statistics, valve statistics, log statistics…).

4

In the fourth window we can see logbook for all installed gas manifolds, plants and control closing boxes. This give us quick review over all activities, changes or errors for each individual installed unit of supply system. Window also contain tab for gas flow review, if we have flow sensor on individual unit of supply system installed.
