ActiveX component designed to be the core part of HMI/SCADA systems based on Visual Basic or any other development tool which supports activex and where it is required to interface with your field equipment through RS-232 and RS-485. Includes more than 100 communication drivers to talk with PLCs, RTUs, power meters, scales, etc. Also offers a powerful communication engine that automatically manages the polling cycle of all the devices connected. Up to 1000 objects can be instantiated. Each object can handle up to 1000 I/O points. Up to 255 COM ports can be used. COM port number, protocol driver and other settings can be changed on-the-fly for each activex object. Provides alarm-detection, PID algorithms and PWM. Bonus LineChart object to graphically display charts based on data-buffers that are automatically stored and updated for each point. Communication messages can be logged to disk for driver debugging. Has a 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. 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. Single and unlimited runtime licenses are available.
