xArrow Software

Feature

1. SYSTEM ARCHITECTURE

2. DEVELOPMENT

All the modules designed in accordance with Windows operating habits, easy to use
The design mode and the run mode can be opened simultaneously
Integrated development workspace to manage the entire project, providing top-down design approach
Entire project data contained in one folder and its sub-folders
Project manager can easily switch and import different project
Simply configure the project by modify the default parameters, all changes are saved instantly
Provide data import/export functions, users can use Microsoft Excel to build tags and structs of the project
Provide emulate PLC to simulating values of PLC variables
Powerful gallery is user-friendly, and easy to create use's own widgets
Drawings can be imported/exported as the template
Without compiling, all changes are WYSIWYG
Script is easy to use, and easy to debug the error

3. DATA ACQUISITION AND SHARING

Built-in support for all the popular PLC (Siemens, GE, Schneider, Mitsubishi, Omron, Delta..., etc.), some of the inverter and some other communication protocols
Communicate via the serial port, TCP/UDP networks and other media
Can be worked as the Modbus/Modbus TCP slave, and support write operation from Modbus/Modbus TCP master
Build-in GraceMaster/GraceSlave protocol, support upload data from xArrow sub-station to xArrow central station
Kernel use Hash algorithms to access real-time database
Data acquisition and process using the event-driven mode
Polling interval is configurable
The write operation has higher priority level than the read operation
Can specify a data to read
Time-stamping of data with millisecond accuracy

4. REAL-TIME DATA

Object-oriented data structures, including the station, string, analog and switch
All the data forming a tree structure depend on the device it belongs
Analog and switch can be configured as read-only or writeable
Analog can be converted to physical values
Analog support simple filtering function
Analog has 5 alarm type, and have deadband
Switch has 3 alarm type
Alarm of the tag can be delayed to prevent false alarm, support used-defined alarm description and can trigger script execution
Use script to access all the information about the tag
System analog show the time, alarm count and communication status of the system

5. HISTORICAL DATA AND ARCHIVE

Can be configured use xArrow’s own database to store all the historical data and alarm, efficiently and quickly
Data can be saved periodically, or when alarm triggered, or according to user's needs
SCADA can be configured waiting some time after startup before begin to save data to avoid incomplete data
Support automatic database cleanup
Use script and SQL statement to access the database
Support export historical data to CSV file

6. ACTION EXECUTION

7. GRAPHICAL INTERFACE

Full vector drawing tools, support for 24-bit true color
Support 24 kinds of fill mode, including 16 kinds of color gradient
Provide Undo/Redo function
Support bitmap transparent, filling, scaling
Support directly copy bitmap from other environment (such as a browser) and paste it into the project
More than 70 kinds of widgets, including text, 3D polyline, real-time data, gauge, waterflow, data grid, historical trends, alarms, buttons, etc.
Support directly copy symbols in Symbol Factory and paste it into the drawing in vector format
Support string search and replace function
The running state of the real-time widget is decide by the given condition
Directly edit the property of the sub-widget of a group widget without ungroup it
Each widget can be configured with tooltip
Unlimited number of drawings, and the single screen sizes up to 10240*7680 pixels
Each writeable widget and each drawing can be set the access permissions

8. ALARM AND EVENT

9. DATA GRID AND HISTORICAL TREND

Data grid and historical trend used to query and display data from xArrow historical database, include daily/monthly/annual data
Data grid and historical trend both support query data by the time and (or) the batch ID
Data grid support 18 kinds of statistics functions, and historical trend support 9 kinds
Data grid and historical trend support load data from CSV file
Data grid support directly load data from the other database via SQL statement
Support save the content of the data grid to CSV file
Add or remove curve item to historical trend at run time
Each curve can have its own mark and axis
The curve can be zoom in and zoom out

10. SCRIPT SYSTEM

Use TCL (Tool Command Language) script, easy to use and efficient
TCL supports math, logic operations, string operation, file operations, and other various commands associated with the operating system
xArrow extend up to 160 command, including real-time database access command, history database access commands, widget operation command, etc.
All the extended commands have detailed document and example
