The new generation of control boards manufactured by Glass Service can solve all of the problems of furnace parameter management.
The control boards are divided in 4 basic model with different electronic architecture but all based on the best modern control technology.
The reliability of the control boards is assured, based upon many years of experience, using only first class materials.
The versions are described below using only Honeywell, Allen Bradley/Siemens and other first class component suppliers.

All the models of Glass Service control board use the “Open System Information” technology (O.S.I.).
This technology allows, the use of the information not only in the furnace control room but also in the local LAN using a Ethernet link.
The information available on the LAN are reported in the single model description.
The control board CF2 are able to send the information stored in memory to a Ethernet link, the information can be send from recorder Sx series and also from the HC 900.

The main feature of this technology are:

• Web Server - With the recorder connected to a LAN, all process variables, alarm and message can be viewed from an internet browser with automatic refresh.

• Remote Viewer - Extends the user interface of the recorder onto the desktop PC.
  Providing full remote control of the unit launched from a web browser. Compatible with Micsoft™ Internet explorer 6 and higher.

• TrendServer Pro - TrendServer Pro is a fully network aware software package for real-time viewing and archiving of data with communications to the recorder. It supports all the capabilities of Trend managementr Pro plus real-time data acquisition and web browser access.
  TrendServer Pro provides secure multi-level, multi-user access to the recorder data by various departments with security.
  Standard features of TrendServer Pro include data archive tools, graphing, print import and export data facilities.

• TrendServer Pro with OPC Server - Provides the same functions as the TrendServer Pro but includes the added function of an integrated OPC Server to allow easy interfacing to third party HMI software packages that support an OPC Client. This provides a real-time interface between servers and clients.

• E-mail server - Some events (alarms, totalizer, etc.) can be send by email to specific address from the recorder and also from the HC900.

• HC900 remote control - All the variable in the DCS HC900 memory can be send by LAN to 3rd party device (PC or other) using Ethernet MODBUS standard or OPC standard. Also by a specific program “Hybrid controller” all the system status (LOOPS, Variable, alarms, etc.) can be read and check by LAN.

The furnace ,distributor and foreheaths are displayed on a graphic display. Some typical samples of the screen are shown in the following description. The PC SCADA CITEC in redundancy version is a full redundant program, all the information is mirrored on the N.2 PC server and can be switched automatically in the case of any failure of the other PC.

LOOPS

The loops controlled by the board are:

• Temperature (input from thermocouple or pyrometer)

• Gas/air ratio

• Oil/air ratio

• Furnace pressure

• Combustion air temperature

The loops installed depends on the specific application. A typical graphic display is shown below.

All the logic parameter and variable are available on the LAN in several format (Ethernet modbus, OPC, etc) and can be send to several device (PC scada or 3rd party device).

ALARMS

The alarms reported are displayed on a double PC+SCADA CITEC operator interface and recorded in HC 900 memory, the mainl alarm groups are:

• High/low temperature

• Device fault (fans - motor)

• Incorrect ratio gas/air or oil/air

• Communication LAN fault

REDUNDANCY

In case of N.1 CPU fault as N.1 power supply fault the CPU N.2 or power supply N.2 will take over the process control automatically without any change to the process conditions in the field.

The redundancy device of the CF2 - RD - SCADA are:

• HC900 CPU70

• HC900 CPU70 power supply

• HC900 I/O power supply

The trend are recorded in internal memory of 500 Mbyte and can be exported using a flash card or a USB memory key. The trends are also reported in the redundant SCADA software. The information is recorded and mirrored in both PCs and in case of a fault with one PC the second will continue recording. In the event that N.1 PC is off line intermittantly, at the first link access all of the logging information lost will be send from the active PC automatically. Using this technology both PCs are recording the logging data without any time hole. A display sample is shown below.
