Hardware Overview
The Fieldbus Round Card is a stand-alone card that allows you to
interface to a network that complies with the Fieldbus Foundation H1
specification. The Fieldbus Round Card uses the Intel 80188EB
embedded processor and a programmable 256 KB
×
8 Flash to run the
Stack Interface Library, Function Block Shell, and user applications. A
128 KB
×
8 SRAM device on the card provides volatile memory.
The Intel 80188EB processor supports two serial ports. You can use one
serial port as a debug port and connect it to the COM port of the host
running the debugger software. A typical application for the other serial
port would be to interface to a device running the serial HART protocol
or other proprietary serial protocol. Both serial ports provide
3 V-compatible signals. The Fieldbus Round Card is capable of
providing a 3.9 V at 8 mA power supply to power your electronics. The
serial ports and the 3.9 V output are accessible from a 2
