Contrôleurs, Régulateurs de température et des fours

A control loop measures process states and compares them to given setpoints. Based on this data a program calculates control values and transmits them to the system. This program can be operated in a storage-programmable logic controller, PLC. The process is controlled by control the actuators like drives or valves with the control values in a small number of cycles. The main benefit of PLC is that instead of assembly or modification relays they are replaced with software.

Often there are control variables like temperature, pressure, revolution speed or flow rate. The control value is measured with a sensor. In case of temperature control it is often realized by thermocouples (T/C). Gasflows are measured and controlled by mass flow controllers (MFC).

The compact Stange Elektronik controller consists of the following components: PID-controller, program controller, I/O-modules for analog and digital in- and output, connected by CAN-bus, user terminal with display and keyboard as well as RS-422 with ModBus-Protocol. The in- and outputs of the controller, the program controller and the I/O-modules can be programmed with an S5 compatible PLC and its instruction set. It is also possible to program without a PC-connection using an user terminal, display and keyboard.

The RS-422 with ModBus protocol offers the possibility to establish a connection to a process control system. There is also an OPC-server available.

Other advantages of Stange program controller are:

Surrogate actual value. In case of a defect sensor the controller switches automatically to a surrogate actual value. If the controller detects a defect thermocouple which should give the actual process value it will automatically switch to a redun-dant thermocouple or a fixed control value (e.g. 20% heating power).

Calculated setpoints. Some furnaces do not have as many set point sensors as actuators. The Stange controller is one of the controller which are able to calculate one or more control values for other actuators based on given setpoints.

Abort recipe. If it is necessary to perform a defined sequence of single steps after process abort this is not easy to realize with a regular sequential program. The Stange controller offers the possibility to load a new recipe (abort recipe) into the program controller and to restart it with this new recipe on a defined condition. This functionality e.g. allows to cool down a furnace in case of emergency in a pre-defined way.

Access protection. All Stange program controller dispose of a multilevel access protection. It can be switched with the PLC an therefore with specific conditions. If e.g. a process recipe is under execution it is possible to abort with a keypress but it is not possible to use this functionality during execution an abort recipe.

Language selection. The user defined language can be set in the menu of the Stange system controller.

Modem connection. It is possible to connect a modem directly to all Stange system controller.

ECS-2000 Process Control System

A common PC can be connected with Stange process control system software ECS-3200 to Stange controller SE-502, SE-504 and SE-510 used in separate furnaces. It is possible to handle up to 16 systems under Windows NT/2000/XP in a system network with integrated modules for configuration, programming and management, online-service with visualisation and logger functionalities, batch data evaluation, and management as well as operating figures and process visualisation.

ECS Recipe Management

An unlimited number of programs, named recipes, can be managed for every system. Like the Windows-Explorer all programs can be sorted in order of the first three program header fields. The program header contents program number, program name, creation date and date of the last modification. For every program 20 information fields can be free configured. There is also a text field available. The recipe input takes place in a clearly arranged table where every raw represents a segment displayed in order of process step, segment time, setpoints and control tracks. There is a user defined number of channels to display setpoint - and control track graphics in real-time. The segments will be shown graphically. The ECS-2000 is a net-work-compatible device.

ECS System Operating

User defined dynamic visualisation can be generated in form of data or animations using the included graph-designer. The user interfaces, e.g. hand level, can be free designed. Program control data is displayed with control functions in a table and setpoint curves synchronous to actual values. This brings an advantage in case of failure analysis because it is easy to compare data curves. Every controller has its own window that displays all parameters in a table, like control zones with description, setpoint, actual value, control value and deviation. All parameters of the data logger (e.g. channels, colours, markers, etc.) with a free selectable number of channels can be configured and saved as a configuration. It is possible to select detailed data information and to position the zoom with a mouse. Available alarms are dis-played with time and status information. Another 256 characters are reserved for additional text. There is also an alarm history, which includes alarm messages, time and status. It is no problem to include the InTouch process visualisation system into an ActiveX-module. A screenshot of the connected Stange device (SE-4xx, SE-5xx) can be displayed at a screen in 1:1 scale. From this side, the device can be remote controlled at all. On a free configurable event a popup window considering the event will be automatically generated.

ECS Analsysis

It possible to manage an unlimited number of batches for every system. A batch sorting is possible by using the first three fields of the batch header (structure like Windows-Explorer). If data logging interrupts, ECS will compile two batches. The first one contents the data be-fore the interrupt and the second one after data log restart. ECS provides a function to merge both batches. The batch header consists of number, operator, label, creation date and data of last modification. Every batch has 20 free configurable fields for additional information (e.g. job number) and a free text field. Logged analog and digital data (max. 200) are displayed graphically. The log data will be saved in a table with a time stamp. There are two recording rates (fast/slow) available. This batch includes a list of system alerts with timestamp, text and status. It is also possible to analyse all recorded channels with graphics and configurable parameters (channels, colours, labels, etc.). An unlimited number of configurations can be saved. For comparison another batch can be loaded at the same time. For analysing 10 batches per channel can be loaded at same time and compared to each other (zoom, reticule).

ECS Designer

Background images can be created with every bitmap tool (e.g. Paintbrush) and will be saved in BMP-format. It is possible to change the background image with the editor but without interacting the animations. Program control data (setpoints, actual values, formula values, etc.) can be displayed with drag-and-drop. It is no problem to input data values in the picture. Three bitmaps (e.g. ON, OFF, ALARM) can be free connected to every digital value by drag-and-drop from a folder. Digital states can be displayed into the picture. This is also possible with free text. With a 3D key another system picture can be displayed; the number of pictures in not limited. The partial graphics functionality offers the possibility to position zoomable bitmaps.

ECS System Configuration

The configuration management is obtained to the single system (tree structure like Windows-Explorer). Up to 16 systems can be managed. The configuration groups are displayed in a clearly arranged table. It is possible to do changes in the table directly. The complete configuration of a system can be saved and reloaded on a single keypress. External data import into the batch protocol is supported. The batch protocol can be initialized on batch start with external data sources per adapter DDE, OPC or file.

Stange controller in new systems and retrofitting of in-stalled systems

Equip new systems with Stange-control systems

On demand for some furnaces from Koyo Thermo Systems it is possible to inte-grate a Stange controller instead of a standard controller to use the benefits of Stange controller. The program controller model varies with the system complexity. Using local peripherals the system can be enlarged on demand with additional modules per digital and analog outputs and also belatedly connected to an ECS-2000.

Reequipment of furnaces

If your actual furnace control does not match your requirements Crystec offers you to retrofit your furnace with a Stange controller to use all its benefits. Because their compact dimensions Stange controller can be integrated space saving and very easy into your existing system while they support process visualisation and storing values and data with a PC adapter.

Stange Elektronik and Crystec are looking forward to install your new furnace system or to retrofit your existing furnace system that matches your strong requirements.
