HMITalk - Develop HMI/SCADA systems using Visual Basic, Delphi or other visual developing tools.

HMITalk

Features

HMITalk comes with a powerful communication engine that automatically manages the polling cycle of all the devices connected.

It allows you to establish a particular scanning time and particular priority for each data packet requested or sent
It dispatches many different "events" to your application when changes in the data received or some other known situations are detected.

With HMITalk, you can simply drag and drop supervision and control capabilities into any container or visual-developing environment that is totally compatible with Visual Basic, to build highly event-driven HMI/SCADA applications. Also, it can be used as the core engine to build DDE/OPC-servers designed to run in the background.HMITalk operates in a system-configuration environment familiar to anyone who has worked with objects: using properties, methods and events. Manipulating the properties, users can select which protocol to use, the alarm levels to assign to each I/O value read, etc. Using the methods, diverse actions can be executed from the user's application, such as triggering the delivery of an output packet, etc. Through the events, the application is informed of everything occurring within the HMITalk objects: if data values change, if an alarm is activated or cleared, etc.

HMITalk also comes with a bonus line-chart control called LineChart that allows you to show the most recent history of the acquired information in a graphical way. Each HMITalk object that you include in you application can manage the reading or writing of a data packet coming from or going to the external field equipment. Data packets can contain anywhere from a single I/O point to 1,000 points each. A "point" represents a signal, variable, memory position, register, timer, counter, status bit, etc., which resides somewhere in the external device and can be manipulated by your application. Up to 1,000 HMITalk objects can work cooperatively in the same computer. They can share the same COM port and use it in turns, they can use different available COM ports and run concurrently, or a combination of both. Even when sharing the same COM port, each HMITalk is capable of managing its own different protocol driver and COM port settings. This means, for example, that you can design your application to communicate with different devices at different speeds using the same RS-485 serial link. On the other hand, various HMITalk objects could be using the same protocol over different ports at the same time. Up to 255 different COM ports can be utilized.The visual appearance of the application, known as the user-interface, is controlled entirely by the user, with application-design tools that are the standard-bearers in today's environment, such as Microsoft Visual Basic or Microsoft Excel. To use an automotive analogy, HMITalk constitutes the engine and chassis, to which the steering wheel, tires, doors, etc., are added using whichever container the user prefers. These environments are so easy to use, even an inexperienced programmer can develop interesting and highly functional applications with HMITalk and a visual language in a question of minutes.

A communication engine to automate data-acquisition from field equipment. Includes various priority levels allowing different levels of vigilance over any or every I/O point and it also includes manual and automatic triggering mechanisms to send outputs to the field
Provides many ready-to-use protocol drivers, plus the ability to easily add new drivers to the package. Includes connectivity with industry-leading PLCs, RTUs, relays, power meters, compressors from industry-leading manufacturers such as Allen Bradley, AEG, Fischer & Porter, Honeywell, Fisher-Rosemount, Honeywell, Foxboro, GEC Alsthom, IDEC Izumi, Mitsubishi, Omron, Siemens, Square D, Texas Instruments and Yokogawa, among many others
The ability to modify its properties in run time, and to make calls to any of its powerful methods.ˇ An alarm-detection mechanism.ˇ Point-value caches with recent history to be plotted with LineChart
A fully-configurable graphical interface through which the communication flow can be monitored, featuring indicator leds, boxes with the messages exchanged and a status box, all of which are continuously updated as long as the communication is active. Communication flow can also be logged to ASCII files for debugging purposes.
