applicom^® product line -
communication solutions for industrial networks

Designed especially for the HMI/SCADA applications, the applicom^® product line provides a wide range of solutions to connect your host applications to your industrial control equipment through industrial networks.
 

Client/Server architecture
The applicom^® architecture supports client/server modes simultaneously.

Configured in client mode, the applicom^® board initiates data exchanges, manages the polling of server/slave devices and enables data collection by your SCADA application.

Configured in server/slave mode, the applicom^® on-board memory maybe written to directly by the industrial control equipment acting as a client. This powerful feature optimises alarm status update to the host application without any polling from the board.

applicom on-board Data-Base
Each applicom board running applicom^® product line has an on-board read/write buffer area of 32 k Bit and 32 k Word . This area called applicom^® Data-Base is ready to use without any additional configuration.

The applicom on-board Data-Base is managed with the use of applicom^® Cyclic Functions. Cyclic Functions are either defined or started by the applicom^® API (Data Server) or defined by the user. The Functions move data to and from the industrial control equipment and maintain a FIFO sequence of events in the on-board Data-Base.

The vast majority of this activity occurs on and is entirely managed by the applicom^® board when running applicom^® product line. Thus, the host computer CPU is not burdened and can very effectively run the very light applicom^® API (Data Server) and host application.

Thus, the applicom^® on-board Data-Base is use to efficiently perform the following data transfers:

• Between Host Applications and Control Devices: The control equipment writes to the on-board Data-Base and the application(s) read, and vice versa.
   
• Between Host Applications: An application writes to the on-board Data-Base and another reads from the same Data-Base. This is useful where the applications are unable to otherwise communicate.
   
• Between Like or Dislike Control Equipment: The applicom^® board performs as a gateway bridge by using the on-board Data-Base for inter-PLC exchanges.
   
• For architectures of the concentrators type, bridges and routers; some of those functions are besides directly integrated in the applicom^® concept.
   
• Between the user tasks embedded on the board and the external environment (equipment, applications) ; for optimal performances, you can develop and integrate your own tasks on the board but also you can use the applicom^® on-board Data-Base for the data exchange with the external environment.
