1.6 How the System Works
Here we will give you an overview of the operation of the DVC5, DVC7 and the DVC10 with the DVC expansion
modules they can control. While not being an exhaustive discussion of the DVC design and operation,
hopefully, this overview will allow you to better understand the Programming Tool and Program Loader Monitor
to see how your system operation is programmed and controlled.
There are 5 fundamental concepts we wish to introduce to you.
1. Each DVC module has a control program or BIOS providing services.
2. All of the expansion modules communicate to the DVC10 master controller and vice versa continuously.
3. Inter module communication and DVC5/7/10 application processing are performed in parallel.
4. The DVC5/7/10 common BIOS executes a defined sequence of operations every 10ms. This cycle time can
be set for anytime between 1 - 20ms and defaults to 10ms.
5. The BIOS provides many services that make application development much easier.
