1. I-8000 Family (C Language)

The 8000 controller comprises a central processor (CPU), power supply, I/O bus,
communication interfaces, front panel control facilities and connectors to plug in various I/O
modules. The 8000 can operate either as an intelligent front end, connected to a host
machine under control of a SCADA package, or as an autonomous controller running an
embedded application. In this mode it is possible to customize the unit to specific
applications.
The main central processing module (CPM) is based on the powerful AMD 80188/80186
series of microprocessors. The CPM can be considered to be an integrated PC comprising up
to 32Mbytes of Flash storage and up to 512K bytes of battery supported SRAM. The
processor runs it's own version of DOS optimised for real time applications. The extension of
the processor bus into the I/O bus permits high-speed data access from the high
performance parallel I/O modules.
In addition to the standard network interface each CPM is supplied with two serial ports
which can be configured to be either RS232 or 485. These ports can be used to extend the
I/O capability of the unit using or alternatively programmed to drive external serial devices.
